Juvelook Skin is an injection treatment that induces collagen formation; changes appear gradually over several weeks, and the degree and duration vary by individual. Swelling, bruising and bumps may occur, and nodules may rarely form. Suitability and the number of sessions are decided after examination.
01Overview
Juvelook Skin
A PDLLA skin booster that firms skin texture from within
Juvelook Skin is a skin booster treatment in which Juvelook, made of PDLLA (poly-D,L-lactic acid) and hyaluronic acid, is injected in small portions into the shallow dermis to improve skin texture.

How we approach it
The same device can be run very differently.
We inject Juvelook Skin with the X-injector. As an injection treatment it does involve some discomfort, but we prepare so that you can receive it comfortably, with less pain, bruising and bumps.
We do not inject a large amount at once to create a visible change right after treatment. We place it in divided portions, only as much as the skin can handle, and we consider it important for collagen to settle evenly.
Dr. Tae Hoon Kim, Medical Director
02What to expect
Changes over time
As the injected PDLLA particles slowly break down, they stimulate collagen formation in the surrounding tissue. Rather than filling the skin instantly, it works by gradually firming the skin's foundation over several weeks.
01Right after treatment
The injection sites may be slightly raised or red. This usually settles within a few hours to a day.
02Days 1–3
Slight swelling and bruising may remain. In most cases it does not interfere with daily life.
032–4 weeks
This is when collagen formation begins. Changes in skin texture are often felt gradually from this point.
04Over the sessions
Changes build up over 2–3 sessions. The next session is decided based on your response.
05Maintenance
Maintenance timing is decided by your progress rather than a fixed schedule.
03Device & Technology
Juvelook Device
PDLLA particles
A slowly degrading biodegradable polymer that stimulates collagen formation in the surrounding tissue as it breaks down.
Hyaluronic acid
Included with the PDLLA, it hydrates the injection site and helps the particles spread evenly.
X-injector
An injection device that delivers in divided portions at a consistent depth and volume, reducing the burden of pain, bruising and bumps.
04Procedure
How your visit goes
01Specialist diagnosis
Using Mark-Vu skin analysis and examination, we check where and how much fine lines, pores and marks are present, and how thick your skin is.
02Planning
We decide which areas need texture improvement and the injection depth and volume, and identify separately any areas that need volume.
03Numbing
Topical numbing cream is applied, and if you are worried about pain, nitrous oxide (laughing gas) conscious sedation can be used as well.
04Injection
The specialist injects evenly in small portions into the shallow layer using the X-injector.
05Aftercare
We explain same-day precautions and when to schedule your next session.
Every procedure is performed directly by a board-certified dermatologist.
05Aftercare
Recovery & care
- 01
Day of treatment
Do not rub or press hard on the injection sites. Gentle face washing is fine.
- 02
First 3 days
Avoid saunas and jjimjilbang (Korean bathhouses), heavy drinking and strenuous exercise. They can make swelling and bruising last longer.
- 03
1–4 weeks
Keep up with sun protection and moisturising. If you feel a lump at the injection site or it becomes red, please contact us right away.
- 04
Follow-up
The timing of your next session is decided together based on your response.
06FAQ
Frequently asked questions
What kind of treatment is Juvelook Skin?
It is a skin booster in which Juvelook, made of PDLLA and hyaluronic acid, is placed in small portions into the shallow dermis to improve skin texture. Because it works by PDLLA particles slowly breaking down and stimulating collagen formation around them, it feels less like an instant fill and more like the skin's foundation firming up over several weeks. It is mainly used for texture-related concerns such as fine lines, pores and shallow marks.
How is it different from Juvelook Volume?
Both belong to the same PDLLA family, but they differ in purpose and the layer they are injected into. Juvelook Skin is placed in small amounts in a shallow layer to refine skin texture, while Juvelook Volume is used to restore volume in hollowed areas. Since different areas of the same face can need different things, we sometimes plan the two separately after examination.
What is the X-injector, and why do you use it?
The X-injector is an injection device that helps deliver a skin booster in divided portions at a consistent depth and volume. As an injection treatment it does involve some discomfort, but using the X-injector helps reduce pain, bruising and bumps (raised swelling at the injection sites). At Grays, we also use it for injecting skin boosters such as BYRYZN and Grays Glow Booster (BICOS™).
Does it hurt a lot?
As it is an injection treatment, you will feel some stinging. We apply topical numbing cream first and inject with the X-injector to reduce discomfort. If you are very sensitive to pain, nitrous oxide (laughing gas) conscious sedation can be used as well, so please let us know during your consultation.
When will I notice the effect?
The smoothness right after injection is often due to swelling and moisture, while the change from collagen formation usually appears gradually over several weeks. The aim is for skin texture to become more refined as sessions build up. The degree of change and how long it lasts depend on your skin condition, age and lifestyle.
How many sessions do I need?
A course is often planned as 2–3 sessions, 3–4 weeks apart. However, we adjust the number of sessions and intervals based on skin thickness, the depth of marks and your response to the first session. The timing of maintenance care afterwards is decided together as we check your progress.
Are there any side effects?
Swelling, bruising and bumps may occur at the injection sites, and most settle within a few days. Rarely, a small lump (nodule) may be felt or an infection may occur, so if the injection site becomes increasingly red or painful, please contact us right away. If you are pregnant or breastfeeding, have inflammation at the injection site, or are taking anticoagulants, please be sure to tell us during your consultation.
Can I combine it with other treatments?
If you also have pore or firmness concerns, we sometimes plan it together with treatments such as Pore XERF or Potenza. Whether to do them on the same day or space them apart is decided based on your skin condition and the treatment areas. If you have had any recent treatments, please let us know in advance.
How much does Juvelook Skin cost, and how do I book?
The cost varies with the injection area, volume and number of sessions, so it is confirmed after examination. Non-covered treatment fees can be found on the pricing page of our website.

Aftercare
Skin boosters · regenerative injections
Needle marks and slight swelling last a day or two. Treatment is usually given in several sessions, so keeping to the interval matters more than the recovery itself.
