Downturned Mouth: Muscle or Sagging | Gangnam Seoul, Korea Dermatology Clinic Guide Some people visit us because they are told they look angry even when they are not making any particular expression. This is a condition where the area below the corners of the mouth appears prominent, and the lines around the mouth point downwards. Even if the impression is the same, the cause can be divided into two, and the approach varies accordingly. Take just one minute to read this. ## Where the Impression is Formed There is a muscle that pulls down the corners of the mouth. If this muscle is overused, the corners of the mouth may appear fixed in a downward position even in normal expressions. In addition, if the tissue in the cheek area sags downwards, weight accumulates around the mouth. This can create a prominent, lumpy appearance.  ## How to Check if the Cause is Muscular Compare your expression when you relax and make a neutral face in front of a mirror, with when you intentionally pull down the corners of your mouth. If it is less noticeable with a neutral face but becomes clear when you exert force, the muscle plays a significant role. Conversely, if it remains the same even with a neutral face, sagging is a greater factor. This is merely a way to estimate, and in reality, most cases involve a combination of both.  ## Approach When the Cause is Muscular The approach is to reduce muscle movement. However, if the dosage and location are not set correctly, the movement of the mouth may become unnatural or pronunciation may become uncomfortable in this area. It is connected to surrounding muscles, requiring delicate adjustment, and there are individual differences in how long the effects last.  ## Approach When the Cause is Sagging An approach that reaches the weighted layer is necessary. Procedures that address the surface skin texture may not be able to change the position of already sagged tissue. Since the layer to be treated varies depending on the depth at which weight has accumulated, there is a process of confirming the layer before proceeding.  ## Summarizing the Two Branches | Observation | Main Cause | Approach Direction | | --- | --- | --- | | Less noticeable with neutral face, clear when exerting force | Muscle tension | Muscle movement control | | Remains the same even with neutral face | Tissue sagging | Lifting that reaches the corresponding depth | | Both apply | Mixed | Divide the proportion and proceed in order | Mixed cases are common, and in such instances, it is best to determine which factor has a greater proportion first and then set the order.  ## Why There's an Order When Proceeding Together Sometimes both approaches are performed on the same day, but not always. If sagging is the main cause but only the muscle is treated, the change may feel minor, and vice versa. It is easier to see results by determining what plays a larger role and then setting the order. We also consider the schedule together due to overlapping recovery periods.  ## Recovery and Precautions Swelling, bruising, and a feeling of pressure may occur, and the degree and duration vary among individuals. The mouth area is frequently used for expressions, so for a few days after the procedure, changes may feel unnatural. It is too early to judge the results during that period. It is safer to consult with medical staff before proceeding to confirm if the method is suitable for your condition. If you are curious about the perceived timing of Lifting & Tightening, you can also refer to the article [When Titanium Lifting Actually Shows](/en/content/when-titanium-lifting-actually-shows-titanium-lifting-in). ## Frequently Asked Questions ### Will treating only the muscle area resolve it? If the cause is predominantly muscular, you may see a change. However, if the tissue has already sagged, that part will remain. ### Will increasing the dosage make it more certain? The mouth area is involved in expressions and pronunciation, so increasing the dosage does not necessarily lead to better results. It is important to precisely determine the location and amount. ### Can I receive both on the same day? It may be possible depending on your condition, but it is better to determine which factor has a greater proportion and then set the order. We also consider whether recovery periods overlap. ### Can I determine my own case? You can get an estimate by comparing your neutral face with when you exert force. However, since cases are usually mixed, it is more accurate to confirm the proportions during a consultation. ### How long do the effects last? This varies depending on the approach, individual muscle usage habits, and tissue condition. It is difficult to state a uniform duration of effect. ## Visit and Consultation Information O.N Clinic is conveniently located near Gangnam Station, making it easily accessible by subway.

Filler or Juvelook for Nasolabial Folds | Juvelook in Gangnam Seoul, Korea Skin Booster Guide The most frequent question in nasolabial fold consultations is, "Is Filler better, or is Juvelook better?" The two are not related in that they produce the same results with different values. Their modes of operation are entirely different. Therefore, instead of asking which is better, you should consider which one is suitable for your condition. Please take just one minute to read this. ## What the Two Methods Do Filler directly fills in sunken areas by injecting a substance. Since the shape changes the moment it is injected, the change is immediately visible. Collagen stimulation methods are different. The substance itself does not create volume; instead, it stimulates the tissue to produce collagen on its own. Therefore, changes appear gradually over time.  ## In Summary | | Immediate Filling Method | Collagen Stimulation Method | | --- | --- | --- | | Time of Change | Immediately after procedure | Gradually over several weeks | | Source of Volume | Injected substance | Collagen produced by tissue | | Reversibility | Relatively possible | Absorbs over time | | Best Suited For | Distinctly sunken specific areas | Overall thinning and loss of elasticity |  ## Why Filler for Nasolabial Folds Requires Careful Consideration The area around the nasolabial folds is close to where blood vessels pass. The results can vary greatly depending on which layer and how much is injected, and injecting too much can lead to an unnatural appearance. Also, the cause of deep nasolabial folds is often not just the hollowness of that area. If the deepness of the fold is due to the weight of the cheek area descending and creating a crease, then an approach that only fills along the line may be misdirected. In such cases, it may be necessary to consider addressing the layer where the weight is concentrated.  ## Collagen Stimulation Methods Also Have Side Effects It cannot be definitively stated that methods that gradually create volume are completely safe. Swelling, bruising, and nodule formation may occur due to the injection itself, and the surface may feel uneven depending on which layer and how much was injected. The degree and duration of these effects can vary from person to person, and it is safest to consult with medical staff before proceeding.  ## Three Factors That Determine the Choice First, timing. If a specific event is approaching, the method that shows immediate changes may be more suitable. Second, the extent of the hollowness. This depends on whether a specific area is distinctly sunken or if there is an overall loss of elasticity. Third, the layer of the cause. If the issue is due to the crease line itself, or if it's a result of the weight from above descending, a filling approach alone may not be sufficient.  ## When Both Are Performed Together The two methods can also be used together, either on the same day or in sequence. However, rather than simply adding them indiscriminately, they are combined after determining what is lacking in which area. Overlapping multiple methods in the same area can lead to excessive volume or an uneven surface. If you are curious about the differences between ingredients, you may also want to read the article that summarizes [What Filler, Rejuran, and Juvelook Each Do](/en/content/filler-rejuran-and-juvelook-do-different-jobs-rejuran).  ## Frequently Asked Questions ### Which one looks more natural? It depends more on the design than the method. The immediate filling method can look natural if the appropriate amount is maintained, and the collagen stimulation method can look unnatural if overdone. ### When do results from the collagen stimulation method become visible? They do not appear immediately. Changes occur gradually over several weeks, so it is too early to judge during that period. ### Isn't it enough to just fill in nasolabial folds? That is true if the cause is hollowness in that area. However, if the deepness of the line is due to the upper tissue descending, simply filling it may be the wrong approach. ### Can side effects be reversed? It depends on the method. In some cases, there is an option to reverse it, while in others, it may be necessary to wait for it to absorb over time. ### What should I confirm during a consultation? Confirming three things—where and how much hollowness there is, whether the weight from above is also a contributing factor, and when your schedule is—can help determine the direction. ## Visit and Consultation Information O.N Clinic is located near Gangnam Station, making it easily accessible by subway. It is more accurate to determine whether the filling method or the collagen stimulation method is suitable by examining both the crease line and the condition of the cheek area.

Filler, Rejuran and Juvelook Do Different Jobs | Rejuran in Gangnam Seoul, Korea K-Beauty Guide "Which of the three is the best?" is a question we often receive. If they could be ranked, all three would not exist side-by-side. Each addresses a different aspect, so the first step is to determine which aspect your concern falls under. Please take just one minute to read this. ## Divided into Three Aspects | | Aspect Addressed | Timing of Change | Best for Concerns | | --- | --- | --- | --- | | Filler | Volume | Immediate | Specific areas are sunken | | Rejuran | Skin texture and condition | Over multiple sessions | Thin, rough, and sensitive skin | | Juvelook | Inducing collagen production | Over several weeks | Overall loss of firmness | It is common for all three aspects to be present on the same face. Therefore, many consultations cannot be resolved with just one approach.  ## What Filler Does Filler directly fills in sunken areas by injecting a substance. Since the shape changes the moment it is injected, the change is immediately visible. However, the layer and amount injected determine the result. Too much can look unnatural, and if the placement is off, the shape may change in an undesired way.  ## What Rejuran Does The purpose of Rejuran is not to create volume. It is closer to addressing the condition of the skin itself. It is a method that involves building up sessions to improve thin, rough skin and skin that easily reddens with irritation. It is not a one-time procedure.  ## What Juvelook Does Juvelook stimulates tissues to produce collagen on their own. The injected substance does not immediately become volume; rather, the collagen produced over time acts as volume. Therefore, the change is not distinct immediately after the procedure and appears gradually over several weeks. If you have an urgent schedule, the timing may not be suitable.  ## How to Choose Formulating your concern into a sentence can reveal the aspect it falls under. "This area is sunken" relates to the volume aspect. "My skin is thin and keeps reddening" relates to the skin texture and condition aspect. "My skin feels generally weak and sagging" is closer to the collagen aspect. If all three sentences apply, prioritize them. It is often easier to see results by determining which aspect has the greatest impact on your appearance rather than doing everything at once.  ## Precautions When Combining Procedures While combining procedures is not inherently problematic, overlapping multiple methods in the same area may lead to excessive volume or an uneven surface. Additionally, the recovery response may be amplified, causing swelling or bruising to last longer than usual. It is important to consider if this overlaps with your schedule. If you are curious about the interval for repeated treatments, you can refer to the article explaining [what sets the Rejuran interval](/en/content/what-sets-the-rejuran-interval-rejuran-in-gangnam).  ## Recovery and Precautions Swelling, bruising, nodule formation, and erythema may occur, and the degree and duration vary from person to person. Especially when performing procedures near blood vessels, it is important to precisely control the layer and amount injected. It is safer to consult with medical staff before the procedure to confirm if the combination is suitable for your condition.  ## Frequently Asked Questions ### How can I summarize it in one sentence? Filler fills, Rejuran addresses skin condition, and Juvelook stimulates collagen production. ### Why do I need repeated treatments? Rejuran and Juvelook work by building up tissue responses, so a single stimulation often does not achieve the desired goal. ### Can I receive all three at once? It is possible depending on your condition, but overlapping them in the same area can be excessive, so it is better to prioritize and sequence the aspects. ### I am concerned about pain. The degree of pain experienced varies greatly from person to person. If you feel uncomfortable during the procedure, please let us know, and we will adjust the speed and method. ### What are the side effects of Filler? In addition to swelling and bruising, depending on the layer and amount injected, the shape may appear unnatural or a feeling of pressure may remain. Areas around blood vessels require particularly careful approach. ## Visit and Consultation Information O.N Clinic is located near Gangnam Station, making it easily accessible by subway. To accurately determine which of the three aspects has the greatest impact on your appearance, it is best to assess both your skin and volume condition.

Peanut Face and What Shot Count Cannot Fix | Face Contouring in Gangnam Seoul, Korea Clinic Guide We often receive the question, "Will 300 shots be enough?" It might seem like a larger number would lead to a greater result, but the shot count is not that kind of value. Especially in cases where the center of the face appears constricted, there's something to determine before the number of shots. Please take just one minute to read this. ## What the Shot Count Means One shot is a unit that delivers energy to one point. If the area to be treated is wider, the required number of shots increases. In other words, 300 shots refers more to the coverage area than to the intensity. Concentrating 300 shots on a small area is a completely different procedure from distributing them over a wide area.  ## What to Determine First | Order | What to Determine | | --- | --- | | 1 | Which area will be treated? | | 2 | Which depth within that area will be targeted? | | 3 | How many shots are needed to cover that area? | The shot count is the last value to be determined. If you decide the number first and then adjust the area, it may be excessive or insufficient.  ## Why Shot Count Isn't the Answer for a Peanut-Shaped Face The causes of a constricted appearance in the middle of the face can be divided into three: whether the cheekbones are prominent, whether the volume below them has decreased, or whether the tissue has sagged. If a decrease in volume is the main cause, a stronger pulling approach might actually make the face appear gaunt. This means that increasing the shot count can sometimes exacerbate the problem. The criteria for distinguishing the causes are summarized in [What to Divide Before Filling a Peanut-Shaped Face](/en/content/three-ways-to-approach-a-peanut-shaped-face).  ## When Considering Combinations If a pulling approach alone is not sufficient, we consider adding volume or addressing skin conditions. However, if multiple procedures are performed on the same day, the recovery responses may overlap. Swelling can make it difficult to judge the results, so we sometimes divide the procedures into separate sessions.  ## The Depth Must Be Correct The layer to which energy is delivered determines the result. Skin and fat thickness vary from person to person, so the same settings may not reach the same depth. This is why we can proceed while checking the layers with an ultrasound screen. We adjust as we go, observing whether the target layer is actually being reached.  ## When to Observe Progress Changes felt immediately after the procedure are more akin to a temporary reaction. There will be a period where they fade within a few days. Changes in elasticity appear gradually over several weeks, so it is more accurate to observe them after the swelling has subsided.  ## Recovery and Precautions You may experience warmth, numbness, swelling, or a feeling of pressure, and the degree and duration may vary from person to person. If you have an important event approaching, it is advisable to check in advance if it overlaps with the recovery period. It is safer to consult with medical staff before the procedure to confirm that the scope and intensity are appropriate for your condition.  ## Frequently Asked Questions ### Can Ultherapy alone resolve the issue? If the cause is primarily due to sagging tissue, you may see a change. If volume loss is also present, that part will remain. ### Will increasing the number of shots improve the results? The shot count is a value for the coverage area, so the number does not directly correlate with the results. If performed excessively on a face with reduced volume, it may lead to a gaunt appearance. ### Is there pain or swelling? You may experience warmth and numbness, followed by a few days of swelling. The degree varies greatly from person to person, and if it feels too strong during the procedure, adjustments can be made. ### Is there a difference depending on the type of equipment? There are differences in the delivery method and adjustment range. However, which layer is treated and to what extent is more relevant to the outcome than the equipment name. ### What is checked during a consultation? First, we identify which axis is causing the constricted appearance in the middle of the face, and which area and depth will be targeted. The shot count is determined after that. ## Visit and Consultation Information O.N Clinic is conveniently located near Gangnam Station, making it easily accessible by subway. Since the shot count is determined after defining the area and depth, it is more accurate to provide guidance after checking your facial condition.

When Titanium Lifting Actually Shows | Titanium Lifting in Gangnam Seoul, Korea Clinic Guide Some people say "I'm not sure right now" as they leave after a procedure. Others come back a few days later and say, "It looks a bit different now." There's a reason why the perceived timing varies for the same procedure. Take just one minute to read this. ## What is felt immediately and what comes later Changes felt immediately after a procedure are mainly the result of the heated tissue contracting momentarily. Your contours may appear slightly more defined in the mirror. However, this is not a long-lasting change. There will be a period within a few days when it feels like it has returned to its original state. Many people judge that "there was no effect" during this period, but the actual changes begin afterwards.  ## Looking at it by timeframe | Period | What appears | | --- | --- | | Same day | Heat sensation, numbness. Temporary contour definition | | 2 days to 1 week | Period when immediate sensation fades. Swelling or stiffness may remain | | 2 weeks to 2 months | Tissue reaction progresses, and changes in elasticity gradually appear | Therefore, a judgment can only be made by comparing photos taken the day after the procedure with photos taken two months later. One or two days is too early.  ## Why the timing differs for each person Skin thickness, amount of fat, and existing elasticity vary. Even with the same settings, the layer reached by the energy and the extent of the reaction will differ. There are also differences depending on age. If tissue reaction is active, changes may appear quickly, otherwise, it may take more time.  ## The first factor determining results: which layer was treated If the layer of concern and the layer reached by the procedure are misaligned, the change may feel small. This is the case when the concern is the skin texture on the surface, but only deep layers are treated, or when the weight is concentrated downwards, but only the surface is treated. If you confirm which layer is targeted before proceeding, it will be easier to understand the subsequent progress. If your concern is sagging in the deep layers, you may also want to refer to the article that explains [which layer buccal fat sagging comes from](/en/content/which-layer-buccal-fat-sagging-comes-from-gangnam).  ## The second factor determining results: repetition interval This is not a one-time procedure. It is a procedure where tissue reactions accumulate, so the perceived effect often changes when repeated with an interval. However, shortening the interval does not necessarily increase the reaction. A waiting period is needed while the previous reaction progresses.  ## What to confirm during consultation You can ask three questions: which layer will be treated and why with that intensity, how many sessions will be done and at what intervals, and when the progress will be checked. These three factors are more closely related to the results than the number of shots or the name of the equipment.  ## Recovery and precautions Swelling, erythema, and a feeling of pressure may occur, and there are individual differences in the degree and duration. If you have an important schedule approaching, it is better to check in advance if it overlaps with the recovery period. It is safer to consult with medical staff before proceeding to confirm if the intensity is appropriate for your condition.  ## Frequently Asked Questions ### Is it a failure if there is no change immediately after the procedure? No. The immediate sensation is a temporary reaction, and changes in elasticity tend to appear over several weeks afterwards. ### When should I take photos for comparison? You can start looking after the swelling has subsided, and comparing with photos taken around two months later will make it easier to judge. ### Will I improve faster if I shorten the interval? Not necessarily. Time is needed for the previous reaction to progress, so shortening the interval does not directly lead to faster results. ### How much pain is there? The degree of pain varies greatly from person to person. If you feel strong pain during the procedure, please let us know and we will adjust the intensity. ### Can I receive it only once? It depends on your condition and goals. Some people are satisfied with one session, while others receive it repeatedly with intervals. ## Visit and Consultation Information O.N Clinic is located near Gangnam Station, making it easily accessible from Yeoksam and Sinnonhyeon areas.

More Rejuran Is Not Always Better | Rejuran in Gangnam Seoul, Korea K-Beauty Guide Many people ask, "Since I'm getting it anyway, should I go with 4cc?" This is likely because the volume feels like a grade, but in reality, there is no such relationship. Volume is not about how good it is, but about how much area is being treated. Please take just one minute to read this. ## How Volume is Determined Injections are administered at multiple points with set intervals. If the treated area is wider, the required amount increases. The amount varies depending on whether you are treating the entire face or specific areas like around the eyes or mouth. Even for the same person, the volume can change if the scope is narrowed or widened in subsequent sessions.  ## Summarized by Area | Treated Area | Tendency | | --- | --- | | Local areas such as around the eyes or mouth | A small amount is usually sufficient | | Entire face | Relatively larger amount | | Additional areas such as neck or back of hands | Increases with the number of areas | In other words, 2cc and 4cc are closer to a difference in coverage area rather than a difference in performance.  ## Problems That Can Arise from Injecting Too Much If the amount injected at one point increases, that spot may feel plump or the surface may feel uneven. Especially in areas with thin skin, the same amount may appear more distinct. This is why increasing the amount when treating the eye area locally may not be helpful. The duration of swelling and bruising may also be prolonged.  ## There are also cases of injecting too little Conversely, if a wide area is divided into small amounts, the spacing between points widens. This can lead to uneven stimulation, and the sensation may vary by area. Neither injecting too much nor too little is the answer; the standard is to determine the appropriate amount for the area.  ## Must be considered with the number of sessions This is not a method of injecting a large amount at once to finish. Since it is a procedure that builds up tissue response, both the number of sessions and the volume are considered together. Rather than injecting an excessive amount in one session, it may be easier to adjust the response by proceeding with an appropriate amount divided over multiple sessions. The criteria for determining the interval are in the article that explains [What Sets the Rejuran Interval](/en/content/what-sets-the-rejuran-interval-rejuran-in-gangnam).  ## What to Check During Consultation You should confirm three things: which area will be treated, how much volume is needed for that area, and how many sessions it will be divided into. If you decide on the number first and then adjust the area, it may result in too much or too little.  ## Recovery and Precautions Swelling, bruising, and a plump sensation may appear at the injection site, and the degree and duration may vary from person to person. These reactions may be more noticeable in areas with thin skin. If you have an upcoming event, it is better to check in advance if it overlaps with the recovery period. It is safe to consult with medical staff before proceeding to confirm that the scope and amount are appropriate for your condition.  ## Frequently Asked Questions ### Which is better, 2cc or 4cc? It is not a difference in grade. If the treated area is wide, the amount increases, and for local areas, a small amount is sufficient. ### Does injecting more lead to better results? If too much is injected at one point, it may feel plump or the surface may feel uneven, so the amount does not necessarily correlate with the results. ### Do areas around the eyes also require a large amount? No. Since the skin in this area is thin, the same amount may be more noticeable, so an appropriate amount suitable for local treatment is used. ### How long do swelling and bruising last? There are individual differences. It varies depending on the area, amount, and recovery speed, so it is difficult to give a uniform answer. ### What should I confirm during the consultation? You should first determine the area and number of sessions, and then confirm the appropriate amount. We do not recommend deciding on the volume number first. ## Visit and Consultation Information O.N Clinic is conveniently located near Gangnam Station, making it easily accessible by subway. The required amount is determined by the area to be treated, so it is more accurate to decide after checking your skin condition.

What Sets the Rejuran Interval | Rejuran in Gangnam Seoul, Korea K-Beauty Guide Many people ask, as if to confirm, "Rejuran is every two weeks, right?" This is likely because they have been informed that way, but this value varies from person to person. It is not the calendar that determines the interval, but the speed at which the skin reacts. Please take just one minute to read this. ## Why Does the Concept of Intervals Exist? Rejuran is not a method that reaches its goal in one go. It is structured to provide stimulation, wait for the tissue to react, and then stimulate again. Therefore, how far the reaction to the previous stimulation has progressed determines the timing of the next session. If stimulation is applied again while a reaction is still in progress, it may not be additive but merely accumulate burden.  ## What Shortens and What Lengthens the Interval? | Condition | Interval Tendency | | --- | --- | | Skin is thin and recovery is slow | Generous | | Recovery is fast and reaction is good | Relatively short | | Experience with prolonged swelling/bruising | Generous | | Initial intensive phase | Shortened initially, then lengthened | Initially, the interval may be shortened to build up the reaction, and then lengthened for maintenance. Maintaining the same interval from beginning to end is not the principle.  ## Does Shortening the Interval Make it Faster? No, it does not. This is because the total amount of stimulation is not directly equivalent to the result. If the procedure is performed again before the previous reaction has subsided, swelling or nodule formation may overlap, and the skin may be stimulated while it is in a sensitive state. Trying to finish quickly can sometimes lead to a longer recovery period.  ## It Also Varies by Area There are cases where the entire face is not treated with the same interval. Areas with thin skin, such as around the eyes, may react differently, so the intensity and timing may be varied by area even within the same session.  ## What to Check When Planning Sessions You can ask how many sessions are planned, what criteria will be used to determine the next session's timing, and how progress will be monitored in between. If you start by only setting a number, there will be no basis for adjustment if the reaction differs from expectations. If the approach is for recovery, such as when the cheeks have sunken after a Fat Dissolving Injection, the timing judgment will differ. You can refer to the article [When Contour Injections Leave Hollow Cheeks](/en/content/when-contour-injections-leave-hollow-cheeks-gangnam-seoul).  ## Recovery and Precautions Swelling, bruising, and a feeling of thickness may appear at the injection site, and the degree and duration may vary from person to person. While these reactions persist, the timing of the next session will be re-evaluated. Even if a date is scheduled, it is safer to adjust it according to the condition. It is advisable to consult with medical staff before proceeding to confirm if the interval is suitable for your skin.  ## Frequently Asked Questions ### Is it always a 2-week interval? No. While shorter intervals may be used initially, it varies depending on recovery speed and reaction, and it is generally lengthened thereafter. ### Why does it differ from person to person? Because skin thickness, recovery speed, and reactions from previous sessions vary. The same interval does not yield the same results for everyone. ### Why is a diagnosis necessary before the procedure? To determine the interval and intensity, the current skin condition and previous reactions must be checked. Without this check, there is no basis for adjustment if only the number of sessions is set. ### What if swelling remains on the scheduled date? It is better to postpone the timing. If stimulation is applied again before the reaction has subsided, the burden may overlap. ### What should I confirm during the consultation? Confirming the number of sessions, the criteria for determining the next timing, and the timing for checking interim progress will make it easier to follow the plan. ## Visit and Consultation Information O.N Clinic is conveniently located near Gangnam Station, making it easily accessible by subway.

Why Nose Pores Need More Than One Approach | Pore Treatment in Gangnam Seoul, Korea K-Beauty Guide Many people are particularly concerned about their nose pores among all facial areas. They say that even with the same treatment, the nose shows results before the cheeks. This difference arises because the conditions of the area itself are different. Please take just one minute to read this. ## Disadvantageous Conditions for the Nose The nose has a relatively large number and thicker sebaceous gland ducts. When these ducts widen, they appear as dots on the surface. Furthermore, the skin here tends to be thick and firm, so the surrounding tissue's ability to support the ducts differs. Therefore, once they widen, it can be difficult for them to return to their original state. The unevenness of the surface also makes them more prominent in side lighting than in frontal lighting.  ## Divided into Two Axes | Cause | Appearance | Approach Direction | | --- | --- | --- | | Widened ducts | Clear like dots | Stimulation to induce tissue response | | Weakened surrounding support | Elongated oval shape | Approach to reinforce support | | Filled with sebum and dead skin cells | Appears black | Problem with the management stage | The third point is more about management than the realm of procedures. The first two are the axes divided in procedures.  ## Approach with Stimulation This method involves delivering subtle stimulation to the inside of the skin to induce a tissue response. The goal is to tighten the area around the widened ducts. This cannot be completed in a single session. Since it is a procedure where reactions accumulate, it is observed over several sessions.  ## Approach to Reinforce Support If stimulation alone is deemed insufficient, the support aspect is also considered. This involves inducing collagen production to support the area around the ducts. The reason for using both approaches together is that they address different axes. It is not doing the same thing twice.  ## Why Diagnosis Comes First The same term "nose pores" encompasses different conditions. The order of treatment may vary depending on whether the main cause is widened ducts or weakened support. If inflammatory troubles are ongoing, the timing may be adjusted. This is because adding stimulation could delay recovery. If you are curious about the overall causes of pores, you may also want to read the article summarizing [Three Causes of Enlarged Pores](/en/content/enlarged-pores-split-into-three-causes-pore-treatment).  ## Sessions and Expectations It is difficult to expect complete resolution in one or two sessions. It is a process that changes little by little over multiple sessions. Also, the original size of the ducts themselves cannot be eliminated. It is more accurate to understand it as aiming to make them less prominent.  ## Recovery and Precautions After the procedure, reactions such as redness, swelling, and scabs may appear, and the degree and duration may vary from person to person. If your skin is sensitive or inflamed, the intensity and timing may be adjusted. UV protection and moisturizing care affect the recovery period. It is safer to consult with medical staff before the procedure to confirm if the combination is suitable for your current skin condition.  ## Frequently Asked Questions ### Is it very painful to do both together? The degree of sensation varies greatly from person to person. If you feel uncomfortable during the procedure, please let us know, and we will adjust the intensity. ### How many sessions do I need? This depends on your condition and goals. Since the number of sessions is adjusted based on the reaction, it is difficult to determine a fixed number from the beginning. ### Can I receive treatment even if I have skin troubles? If inflammation is ongoing, it is better to adjust the timing. Adding stimulation could delay recovery. ### What should I do if redness persists for a long time after the procedure? Redness for a certain period is a normal reaction during the recovery process. If it lasts longer than expected or causes discomfort, it is safer to have it checked. ### What criteria should I use to choose between different methods? It depends on whether the main cause is widened ducts or weakened support. That judgment comes before the choice. ## Visit and Consultation Information O.N Clinic is located near Gangnam Station, making it easily accessible by subway.

When Contour Injections Leave Hollow Cheeks | Gangnam Seoul, Korea Dermatology Clinic Guide There are cases where people come to us saying their cheeks look hollow after having their jawline refined. They say that shadows appear in the mirror, making them look older. At this point, it is necessary to decide what to wait for and what to address. Please take just 1 minute to read this. ## Why Hollowing Occurs Fat Dissolving Injection works to reduce fat. If the area you intended to reduce and the area that actually reduced are misaligned, or if more than the necessary amount is administered, the area may appear sunken. If you originally had less cheek fat, hollowing may be more pronounced with the same amount. This is even more true if the volume has already decreased with age.  ## What to Distinguish First | Condition | Judgment | | --- | --- | | Temporary change due to swelling subsiding | Observe the progress over time | | Volume loss due to fat reduction | Difficult to expect natural recovery | | Condition where sagging is also present | Filling approach alone is insufficient | Immediately after the procedure, it is difficult to judge due to swelling. If it remains the same after a few weeks, it is considered volume loss.  ## Does it Return on its Own? It is difficult to expect the reduced fat to be refilled. However, there are periods when the impression may look slightly different due to overall facial volume changes. Therefore, we recommend observing the progress over time before making a judgment.  ## When Approaching for Recovery There are approaches that add volume to the hollowed area and approaches that address the skin condition. If volume loss is clear, we consider filling, and if the surface feels thin and the skin texture rough, we consider both skin and volume. Often, both conditions overlap. In either case, it is safer to proceed in stages and observe the reaction rather than trying to reverse it all at once, as the area has already been stimulated.  ## Why it's Better to Consult Sooner As time passes, the surrounding tissues settle into place according to the hollowed area. This makes it difficult to plan based on the original shape. Also, the more records there are about which areas and how much was administered, the more accurate the judgment will be. It helps if you organize and bring information about the time, area, and number of sessions as you remember them.  ## Recovery and Precautions Additional procedures may also cause swelling, bruising, or a feeling of fullness, and the degree and duration may vary from person to person. Since the area has already been stimulated, it may feel more sensitive than usual. It is often started with a lower intensity and amount. It is safer to consult with medical staff before proceeding to confirm if it is suitable for your current condition. The criteria for setting the repeat interval are summarized in the article [What Sets the Rejuran Interval](/en/content/what-sets-the-rejuran-interval-rejuran-in-gangnam).  ## Frequently Asked Questions ### Why are my cheeks hollow? This occurs when the area you intended to reduce and the area that actually reduced are misaligned, or when more than the necessary amount was administered. If you originally had less cheek fat, it may be more pronounced with the same amount. ### Will it return over time? It is difficult to expect the reduced fat to be refilled. However, it is better to postpone judgment in the early stages when swelling is present. ### Is filling alone sufficient? Yes, if there is only volume loss. If sagging is also present, the impression may not be refined with a filling approach alone. ### Are there side effects with additional procedures? Swelling and bruising may occur, and since the area has already been stimulated, it may feel more sensitive. ### When is the best time to consult? If the condition remains the same after the swelling has subsided, it is best to check at that time. Organizing the treated areas and number of sessions will help with the judgment. ## Visit and Consultation Information O.N Clinic is conveniently located near Gangnam Station, making it easy to access by subway.

Three Ways to Approach a Peanut-Shaped Face | Face Contouring in Gangnam Seoul, Korea Clinic Guide Many people are concerned that their cheekbones are prominent and the area below them is sunken, making the center of their face appear constricted. They often say that their face looks particularly shadowed and older in frontal photos. This shape does not have a single cause; it's necessary to first determine what makes it appear that way. Take just one minute to read this. ## Same Shape, Different Causes | Cause | Appearance | | --- | --- | | Cheekbones are naturally prominent forward or sideways | Upper part is emphasized, making the lower part appear more sunken | | Volume below the cheekbones decreases | Shadows appear and lines are etched | | Tissue sags downwards | Upper part becomes hollow, lower part becomes heavy | In most cases, these three factors are mixed, so we first assess which factor has a greater proportion.  ## Why Filling Alone Often Doesn't Work Adding volume to a sunken area will fill it in at that moment. However, if the cause was sagging tissue, it means you are adding more volume to an area where weight has already accumulated. This could make the face appear larger or feel heavy. If prominent cheekbones were the main reason, filling the lower part would still leave the contrast between the upper and lower parts unchanged.  ## First Approach: Adding Volume This approach is suitable when there is an actual lack of volume in the sunken area. There are methods that provide immediate filling and methods that induce collagen production over time, and the choice depends on your schedule and desired speed of change. It is often more natural to distribute the volume by considering the overall flow of the face rather than concentrating it in one spot.  ## Second Approach: Addressing Skin Condition Thin and weakened skin can make the same volume loss appear more deeply etched. In such cases, addressing the skin's condition itself can sometimes have a greater impact on facial impression than simply filling. This approach involves multiple sessions.  ## Third Approach: Addressing Sagging Tissue If the main cause is the downward pull of weight, we consider methods that target that specific layer. In this case, starting with a filling approach would be misdirected. This is a point where simply changing the order can alter the outcome. For deep layer sagging, you can refer to the article that explains [which layer buccal fat sagging comes from](/en/content/which-layer-buccal-fat-sagging-comes-from-gangnam).  ## Criteria for Determining the Order We start by addressing the factor among the three axes that has the greatest impact on the overall impression. If everything is addressed at once, it can be difficult to determine what caused the effect, and there is a risk of over-treatment. It is safer to proceed in stages, observing the reactions, and then deciding on the next step.  ## Recovery and Precautions Swelling, bruising, and a feeling of thickness may occur, and the degree and duration can vary individually. If multiple methods are performed on the same day, the reactions may be compounded, potentially extending the recovery period. We consider this in conjunction with your schedule. It is safe to consult with medical staff before proceeding to confirm that the sequence is appropriate for your condition.  ## Frequently Asked Questions ### Can it be improved with Filler alone? If volume loss is the main cause, it can be helpful. If sagging tissue is the cause, a filling approach alone may not resolve it. ### Should I avoid putting in too much? Concentrating too much in one spot can make the face appear larger or feel heavy. It is better to distribute it by considering the overall flow of the face. ### Which should I do first: address skin condition or add volume? We start with the axis that has a greater impact on the overall impression. If thin skin is the main reason, that may be the priority. ### How long do swelling and bruising last? It varies depending on the area, method, and recovery speed. If multiple procedures are performed together, it may last longer. ### How do I determine which axis my face falls under? We examine the face from the front and side, assessing the degree of cheekbone protrusion, the volume of the lower part, and the extent of tissue sagging. Often, it's a combination, requiring a judgment to determine the predominant factor. ## Visit and Consultation Information O.N Clinic is located near Gangnam Station, making it easily accessible from the Sinnonhyeon area.
