You might have been surprised when you looked in a mirror head-on and everything seemed fine, but then saw a side-profile photo someone took of you, and only your lips seemed to protrude forward. This is precisely what those considering lip filler fear most.
"I asked for it to be subtle, but from the side, my lips look like they're floating. When I smile, my upper lip feels stiff." You can easily find such complaints in online communities. Every time I read them, as a doctor, I feel a sense of regret.
Welcome.

I am Dr. Oh Seung-min, the lead director of O.N Clinic in Gangnam. The lips are a small area, and even a slight enhancement can change one's impression. A well-performed lip filler procedure can make the entire face appear more vibrant. Conversely, if you continue to feel awkward after the procedure, it might not simply be a problem caused by increasing the injection volume.
In many cases, the treatment plan was determined by looking only at the lips in isolation. Methods such as injecting a fixed amount based only on lip size, focusing only on the front view without checking the side profile, or trying to solve the problem with only one product...
If the treatment approach is like this, you might experience repeated dissatisfaction even if you dissolve the filler and get it again. Therefore, today, I would like to honestly tell you what needs to be considered first for natural-looking lip filler, and why I chose Teoxane.
It will be enough if you take just 3 minutes to read it. ^^ If you understand what a lip filler procedure that considers the side profile entails, you can significantly reduce the chances of regretting it afterward. Natural-looking Lip Filler, Why Did Gangnam O.N Clinic Choose 'Teoxane'?

Concluding remarks
1. Why might lip filler not look natural?

Before choosing a product, there's a question that needs to be addressed. Why does lip filler look natural on some people, but awkward on others? Often, people think it's "because too much was injected" or "because the lips were originally thin."
Upon closer inspection, the cause is often ultimately one thing: the lips were not viewed within the overall proportion of the face. The lips do not exist in isolation. From the side, how much the lips protrude within the line connecting the tip of the nose and the tip of the chin determines the impression, and from the front, it's important whether the length and thickness of the lips are harmonious with the width of the cheekbones and jaw.

Only when the balance between the upper and lower lips, the shape of the Cupid's bow, and the direction of the corners of the mouth are all aligned, does it finally feel like 'my original lips'. If even one of these is out of alignment, the result changes. If someone with a short chin only increases lip volume, their mouth might appear to protrude from the side profile. If only the thickness is added to a face with wide cheekbones without considering the width of the lips, the lips might appear detached.
Therefore, I do not determine the amount by simply looking at the lip size and saying, "I'll inject a few cc." So, even if the same proportions are considered, where does the difference in results come from? Let's examine this one by one.

2. Why did O.N Clinic choose Teoxane for natural-looking lip filler?

The first aspect to consider is the 'movement' of the lips. The lips are an area that constantly stretches and contracts every time we speak, eat, and smile. It's no exaggeration to say they are one of the busiest moving parts of the face.
When reviewing feedback about awkward lip filler, there's a common expression: "It's fine when I'm still, but it bunches up when I smile," or "My upper lip moves less when I speak." Even if the proportions are well-matched, if a product that cannot follow the movement of the lips is used, the feeling described above might remain.
Teoxane is a hyaluronic acid (HA) filler brand made in Switzerland, known by the name Teosyal. Among them, the RHA line is introduced as a filler designed to stretch and return in sync with facial movements.
It also has a separate KISS line for subtle volume and contouring. This is also why I chose Teoxane. When performing a lip filler procedure, the areas that need volume, the areas that need clear contouring, and delicate areas like the corners of the mouth each require different properties.
Therefore, I saw that being able to choose the appropriate line within the Teoxane brand, tailored to the area and purpose, helps to match both proportion and movement. (Teosyal filler, what kind of product is it?)
Of course, this does not mean that other fillers besides Teoxane are not good. Every filler has its advantages and limitations. As Teosyal is also a hyaluronic acid (HA) filler, swelling or bruising might occur after the procedure, and since the labial artery runs inside the lips, the possibility of rare vascular complications should also be considered.
Ultimately, what's important is not the product name, but which layer and area of your lips, and with which line, that product is used. Before the procedure, I check the front, side profile, smiling expression, cheekbones, chin, and nose tip together, and also examine the proportions with the lips.
Then, considering the course and layers of the labial artery, I divide the areas to be filled for volume and those to be refined for contour, and I personally design the appropriate line and amount for each area. I do not recommend excessively enlarging the lips relative to the proportions, and I also monitor the process of swelling subsiding and the filler settling after the procedure.
During consultation, it's also a good idea to ask, "Considering my side profile and cheekbone proportions, what lip size would suit me?" Natural-looking Lip Filler, Why Did Gangnam O.N Clinic Choose 'Teoxane'?

Frequently Asked Questions
My lips are thin, and I'm worried that if I enlarge them, they'll look like duck lips.
Unnaturally large-looking lips are often caused by not matching the facial proportions rather than the amount injected. You can reduce this concern by first determining a suitable thickness within the proportions of your side profile, cheekbones, and jaw.
From the side, my mouth looks recessed. Is it because of my lips?
The side profile is influenced not only by lip thickness but also by the position of the nose tip and chin tip. It is advisable to first check the overall proportions of your facial profile rather than just filling the lips.
I often hear that I look angry because the corners of my mouth are downturned.
Downturned corners of the mouth can have various causes, such as lack of volume, muscle tension, or skin laxity. The treatment approach varies depending on the cause, so it's best to first identify why the corners of your mouth appear downturned.
