Skin boosters & collagen stimulators
In short
Skin boosters are injections placed thinly at many points in the dermis to improve the skin's base, such as texture, inner dryness and firmness. By ingredient, they include hyaluronic acid (hydration), PN (regeneration) and collagen-stimulating ingredients. They are mainly considered by people whose skin feels rough and dry underneath, or who are concerned about texture, fine lines or loss of firmness. The number of sessions differs by ingredient: we suggest 3 sessions 2–4 weeks apart for Rejuran and 3 sessions 1 month apart for Juvelook Volume. Needle marks or small bruises may be visible for a few days after treatment.
| Duration | Injection time is about 2–20 minutes (plus 20–30 minutes for numbing cream). |
|---|---|
| Anesthesia | In most cases, numbing cream is applied and treatment starts after 20–30 minutes; local anesthesia by injection is sometimes added to reduce pain further. |
| Recovery | Needle marks, bruising and swelling may occur and mostly settle within a few days. |
| Interval & sessions | The standard is 3 sessions 2–4 weeks apart for Rejuran, 3 sessions 1 month apart for Juvelook Volume and Sculptra, 3 sessions 1 month apart or every 3 months for Revive, 2–3 sessions 1 month apart for Radiesse, and every 2 weeks for water-glow injections. |

How it works
PLLA (Sculptra) and PDLLA (Juvelook) are dissolvable polymer microparticles. When placed in the skin, they stimulate the skin around the particles and prompt the body to make its own collagen. So unlike filler, which adds volume right away, changes appear gradually over several weeks. Juvelook is PDLLA mixed with hyaluronic acid, and Sculptra is a PLLA product.
PN (Rejuran) is purified from salmon DNA and aims to improve texture and firmness by supporting skin regeneration. Hyaluronic acid skin boosters (water-glow injections) place non-cross-linked hyaluronic acid shallowly to replenish hydration and texture. Intradermal botulinum toxin (skin toxin) is injected in very small amounts at many points in the shallow skin layer, not the muscle, with the aim of improving fine lines, texture, pores and oil.
What happens on the day
At the consultation, we check which concern matters most to you, such as inner dryness, texture, firmness or hollowness, and choose the ingredient. For inner dryness and texture, we mainly consider hyaluronic acid or PN; for firmness and collagen support, PDLLA or PLLA. Several ingredients are sometimes combined depending on your skin.
We clean the injection area, apply numbing cream and you usually wait about 20–30 minutes. Please tell us about any medication you take (especially blood thinners) and allergies before this step.
The chosen ingredient is placed thinly at many points in the dermis. Hand injection allows fine control of depth and amount, while machine injection (injector) is faster and less painful but some product leaks out. Collagen stimulators are fully dissolved and placed in small amounts so they do not clump.
Right after treatment, needle marks may look red, and small bumps or small bruises may appear. We give you written aftercare instructions, and for treatments that need massage, such as Juvelook Volume and Sculptra, we explain the method and how long to do it separately.
Safety
Who should not have it
- If you are pregnant or breastfeeding, or allergic to an injected ingredient, we postpone or avoid treatment. If you have a history of allergies such as fish allergy, take blood thinners or have an autoimmune disease, please be sure to tell us before treatment. The doctor checks and then decides whether to proceed.
- If the treatment area has inflammation, a wound or dermatitis, it is better to wait until it settles, and we also advise postponing when you are unwell, such as with a cold or fever. Bruising may last a few days, so leave some time before important events.
Side effects and cautions
- Common reactions are redness at needle marks, small bruises, small bumps (wheals) and swelling. Redness after Rejuran usually lasts 3–4 days, and bruising usually fades in a few days to about a week, though it may last longer for some people.
- Rarely, collagen stimulators (Juvelook, Sculptra) may cause nodules (lumps), so we fully dissolve them and place them in small amounts. Massaging at home 3 times a day for 5 minutes after treatment helps prevent nodules. If you feel a lump, or a bruise keeps growing and hurts, contact us right away.
Aftercare and your flight home
- Unless you were given massage instructions, do not rub the injection area hard. Face washing and light makeup are usually suggested from the next day (based on Rejuran), and if redness remains, reduce irritation and apply moisturizer and sunscreen well.
- Until redness and swelling settle, it is better to avoid saunas, intense exercise and alcohol for about 1 week. The next visit is scheduled according to each ingredient's interval: usually 2–4 weeks for Rejuran and 1 month for Juvelook.
- After injection treatments, flying is usually possible the same day or the next day. However, bruising may last a few days, so if possible we suggest having treatment early in your trip and checking your progress while you are still in Korea.

Questions about this treatment
How do you choose the skin booster ingredient?
Each skin booster works differently and has a different goal, so we suggest the option that suits your skin condition and main concern (wrinkles, pores, firmness, hydration, volume). For inner dryness and texture, we mainly consider hyaluronic acid or PN (Rejuran); for firmness and collagen support, PDLLA (Juvelook) or PLLA (Sculptra); and to gradually fill wide hollow areas, Sculptra.
Do skin boosters hurt? Is anesthesia used?
Because many shallow injections are given, there is a stinging pain, and how much depends on the ingredient and area. There are three methods: hand injection, machine injection (injector) and cannula. In most cases, numbing cream is applied and treatment starts after about 20–30 minutes. Local anesthesia by injection is sometimes added to reduce pain further, and skin toxin usually skips the nose and upper lip, which are especially painful.
Can I return to daily life right after skin boosters?
Yes, recovery from injection treatments tends to be short. Redness at needle marks, small bruises or small bumps may appear: redness from Rejuran usually lasts 3–4 days, and bumps from skin toxin mostly settle within 3–4 hours. Face washing and light makeup are usually suggested from the next day.
How many skin booster sessions do I need, and how often?
It depends on the ingredient. We suggest Rejuran as a set of 3 sessions 2–4 weeks apart, about 2 sets a year; Juvelook Volume and Sculptra as 3 sessions 1 month apart; Revive as 3 sessions 1 month apart or every 3 months; and Radiesse as 2–3 sessions 1 month apart. Water-glow injections can be done as often as every 2 weeks, and skin toxin is usually repeated every 3–4 months. We adjust the number of sessions based on your skin condition and response.
