Key Summary: The intensity of pain experienced with Rejuran is not directly proportional to its effectiveness.
Even with the same amount injected, the perceived pain can vary significantly depending on the anesthesia method, injection speed, and the practitioner's technique.
Therefore, when reading reviews, what you really need to check is not "how much it hurt."
It's about how the pain was managed and how the treatment was designed to suit your skin.
Take just one minute to read this.
"Inject it painfully," is that really okay?
When consulting about Rejuran, we often hear remarks like, "If possible, make it painful and fill it up completely."
This is because the belief that more pain means greater effectiveness is quite firmly established in review culture.
It's an understandable sentiment. Since it's a procedure you're paying for, you want to feel confident that you've "received it properly," even if it's just through sensation.
However, from a medical professional's perspective, the relationship between pain and effectiveness is not that simple.
Pain is not a sign that the procedure is going well; it's closer to a result created by that day's anesthesia and injection method.
If your areas of concern are not yet clear, it's a good idea to discuss the treatment options together from the start.
Referring to the Treatment Guide for Skin Concerns by Age Group in Your 30s which summarizes concerns by age group, can help you set a direction before your consultation.
Is the intensity of pain really proportional to the effect?
To put it simply, there is no direct proportional relationship between the intensity of pain and the effectiveness of the treatment.
Rejuran is a procedure that repeatedly injects ingredients into various points within the skin.
It's a natural reaction for some dullness to accompany the process of the needle being inserted multiple times, given the nature of the procedure.
The problem lies in interpreting the magnitude of this sensation as the magnitude of the effect.
What actually determines the results of Rejuran are two things, not pain.
One is whether the ingredients were injected evenly at the appropriate depth, and the other is whether the skin's subsequent regenerative process, leading to collagen production, proceeds well.
The fact that it hurt moves independently of these two conditions.
Therefore, the expectation that 'it hurt a lot, so the effect must be great' may be an unsubstantiated judgment.
Why does the pain differ for the same Rejuran?
Even when the same amount of Rejuran is injected, the pain experienced varies from person to person and from clinic to clinic.
The factors that determine perceived pain are roughly divided as follows:
- Anesthesia method: Whether anesthetic cream was sufficiently applied, and whether sleep anesthesia is an option when needed.
- Injection speed: Whether it's pushed in quickly, or slowly and gently divided.
- Sensitivity of the area: Whether it's a sensitive area like around the eyes or mouth, or a relatively less sensitive area.
- Practitioner's technique: How consistently the insertion angle and depth are maintained.
If injected slowly with sufficient anesthesia, the pain may be felt much less, even with the same dosage.
In other words, a less painful procedure does not necessarily mean a less effective procedure.
In fact, procedures with well-managed pain often lead to a higher degree of completeness in results.
The pattern of pain may also be reported differently depending on the type of Rejuran.

Reviews: Look at these two things instead of pain
Referring to reviews is not bad in itself.
However, where you focus your attention changes the quality of the information.
From a clinical perspective, useful criteria are not the intensity of pain, but the two points below:
| Commonly noticed aspects | Actually useful aspects to refer to |
|---|---|
| How much it hurt | Was pain management sufficient? |
| How many cc were injected | Was it designed to suit my skin condition? |
| How severe was the swelling | Was a meticulous approach taken for each area? |
First, pain management.
If a review reveals whether anesthetic cream was sufficiently applied, whether sleep anesthesia is an option when needed, or whether sensitive areas were approached separately, it holds high reference value.
Second, injection design.
Rejuran comes in various types, and the appropriate dosage and injection depth vary depending on the skin condition and area of concern.
A review that describes 'how it was designed based on my skin texture, elasticity, and areas of concern' is much more valuable than a mere number like 'I received X cc'.
The article Things to Check When You Feel Rejuran Has No Effect, which addresses the reasons why effects might not meet expectations, can also help you read reviews in a balanced way.
Before the procedure, check in this order
The impression gained from reviews is just a starting point; the final decision is made during a consultation with a medical professional who has directly examined your skin.
We recommend following the steps below before and after your consultation:
- First, clarify your main concerns: whether it's skin texture, elasticity, or specific wrinkles.
- During the consultation, specifically confirm the pain management methods (anesthetic cream, availability of sleep anesthesia).
- Instead of requesting the exact dosage and method seen online, ask for a design tailored to your skin condition.
- Before the procedure, confirm potential reactions such as swelling, redness, bruising, temporary pain, and how to manage them.
(※ The effects and reactions of Rejuran may vary depending on individual skin conditions.)
After the procedure, swelling, redness, bruising, and temporary pain may appear at the injection site. Most of these are temporary, but if symptoms persist or worsen, it is necessary to consult with a medical professional.
Please remember that the dosage and injection method should be determined through examination and consultation.
Chat for a consultationFrequently Asked Questions
Is Rejuran more effective the more it hurts?
The intensity of pain and the effectiveness of the procedure are not directly proportional.
Pain varies depending on the injection speed, anesthesia method, sensitivity of the treated area, and the practitioner's technique. The effectiveness of Rejuran depends on whether it was injected evenly at the appropriate depth and the subsequent collagen regeneration process of the skin.
Are there ways to reduce pain during Rejuran treatment?
Applying anesthetic cream sufficiently or opting for sleep anesthesia when necessary can significantly reduce pain.
Perceived pain can also vary depending on the injection speed and method, so consulting with a medical professional about pain management methods before the procedure can be helpful.
What information should I refer to when reading Rejuran reviews?
Reviews that focus on whether pain was adequately managed and whether the treatment was designed to suit the individual's skin condition are more useful than those that focus on 'how much it hurt'.
We recommend referring to reviews that mention the design process tailored to the skin condition, rather than just the number of 'cc injected'.
Can swelling or bruising occur after Rejuran treatment?
Yes, swelling, redness, bruising, and temporary pain may appear at the injection site.
Most of these are temporary reactions, but if symptoms persist or worsen, it is advisable to consult with a medical professional.
Are the effects of Rejuran treatment the same for everyone?
No. The effects and reactions of Rejuran treatment may vary depending on individual skin conditions.
Even the same procedure can yield different results depending on skin type, condition, and areas of concern. Therefore, it is important to have a thorough consultation before the procedure to determine the method best suited for you.

Recovery and Downtime
Rejuran is a procedure that injects ingredients into various points within the skin, so immediately after the procedure, swelling, redness, numbness, and small bruises may appear at the injection site.
These reactions generally subside within a few days, and there may be individual differences depending on skin condition, injection area, and anesthesia/injection method.
For sensitive areas like around the eyes or mouth, swelling or bruising might be a bit more noticeable, so it's more comfortable to schedule the procedure with ample time if you have important events.
On the day of the procedure, avoiding excessive heat stimulation (sauna, strenuous exercise, alcohol) and not rubbing the injection site vigorously can aid recovery.
If symptoms persist for a long time or worsen, we recommend consulting with a medical professional rather than attempting to self-treat.
How the Cost is Structured
The cost of Rejuran is not a fixed amount but is determined by several factors.
It varies depending on the type of Rejuran used, the amount (cc) and injection area used at one time, whether the treatment area is the entire face or a specific part, the anesthesia method (anesthetic cream, availability of sleep anesthesia), and whether post-care or return visit packages are included.
Therefore, it is difficult to assume that the amount seen in reviews or advertisements will be your exact cost.
The accurate cost will be provided during a consultation after directly examining your skin condition and areas of concern.
