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.
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.
