"It hurt, so the results must be good, right?"
Many people say this as they leave after receiving Rejuran Healer.
However, the intensity of pain and the treatment results are not directly linked.
This is because there are separate factors that determine pain.
Take just one minute to read this.
Two Sources of Pain
Rejuran Healer involves injecting the ingredients into the skin multiple times.
Therefore, pain comes from two sources.
| Cause | Description |
|---|---|
| Number of Injections | Stimulation from the process of injecting into multiple points |
| Ingredient Characteristics | Often accompanied by a unique dull ache when injected |
Both of these are natural reactions to some extent, as they stem from the nature of the procedure.
The problem arises when this pain is misunderstood as an indicator of results.
(※ Effects and reactions may vary depending on individual skin condition, and suitability for the procedure is determined through consultation with medical staff.)
The Sensation Differs Even with the Same Amount
What determines the sensation of pain is not the amount injected, but how it was injected.
- Whether anesthesia was sufficiently applied and given time to absorb
- Whether the injection speed was slow
- Whether the order and depth were adjusted according to the sensitivity of each area
Even with the same Rejuran Healer, it may hurt less if sufficient anesthesia is used and it's injected gently, and it may feel more painful if injected quickly.
In other words, pain is likely related to "how it was administered" rather than "a lot was injected."
Sensitive Areas Like Around the Eyes
Even within the same face, there can be a significant difference in pain depending on the area.
Areas around the eyes, where the skin is thin and nerves are concentrated, tend to feel more sensitive than other areas.
For such areas, the injection depth and speed may be adjusted separately, and the order may be delayed to allow sufficient time for the anesthesia to take effect before proceeding.
If you tell us "which area you are most concerned about" before the procedure, we can design the order accordingly.
So, What Should Be Used to Judge?
If pain is not the indicator, what should we look for?
More than the procedure itself, it's about whether the necessary amount was injected into the correct layer.
This is confirmed not immediately after the procedure, but by changes in skin texture over several weeks.
Rejuran Healer is a procedure that focuses on skin texture and regenerative power rather than immediate volume changes, so comparing the progress in terms of sessions is more accurate.
The goal is to reduce pain while precisely injecting where needed, not to endure pain.
Frequently Asked Questions
Is it true that Rejuran Healer is more effective the more it hurts?
No, that is not true. The intensity of pain and the results are not directly linked, and the sensation can vary greatly depending on the anesthesia method, injection speed, and adjustments for each area.
How can I reduce the pain?
Sufficiently applying anesthesia and allowing time for absorption, injecting slowly, and adjusting the order and depth for sensitive areas may help.
Will there be bruising or swelling after the procedure?
Since it is injected into multiple points, temporary bruising, swelling, or red spots may appear for a day or two. The degree and duration may vary from person to person.
I've heard that the area around the eyes is particularly painful.
This area tends to feel more sensitive than others because the skin is thin and nerves are concentrated. The injection depth and speed may be adjusted separately, or the order may be delayed before proceeding.
What should I confirm before the procedure?
It may be helpful to confirm during the consultation how anesthesia will be administered, which areas will be treated in what order, and how the sessions are planned.
Recovery and Downtime: Progress of Injection-Based Procedures
Red spots or small swellings may remain for a day or two along the injection sites, and if bruising occurs, it may last for a few more days.
It is advisable to avoid saunas or strong massages for the first two days.
Changes in skin texture appear gradually over several sessions, not immediately after the procedure, so it is advisable to schedule important events with a few days of leeway.
How is the Cost Determined?
The cost is not determined by the volume alone.
It varies depending on which areas are treated, whether sensitive areas like around the eyes that require separate adjustment are included, and how many sessions are planned in total.
Whether anesthesia and post-procedure soothing care are included also affects the cost.
For an accurate cost, it is best to provide guidance after a consultation to assess your skin condition.
