Polynucleotide (PN), hyaluronic acid (HA) and poly-D,L-lactic acid (PDLLA) are three ingredient families used in skin booster injections, which place small amounts into the skin for hydration, fine texture and firmness with no aim of adding volume. For a skin booster in Seoul, ENTER Plastic Surgery lists Rejuran, Skinvive, Re2O, Juvelook Skin, water glow and exosome, each injected in 20–30 minutes under numbing cream.
Treatments
Which skin booster works on which skin concern
Every product on this page goes into the skin itself, in many small deposits spread across the face. What separates them is the material left behind and what that material is meant to do there: hold water, support the repair of thin or tired skin, or prompt slow collagen building. The groups below follow that logic, so the choice starts from the skin concern and works back to a product name.

Rejuran products contain polynucleotides, chains of DNA fragments that act as a scaffold in the skin. A pharmacology review traces the related compound PDRN to an effect on the adenosine A2A receptor, a pathway linked to wound healing in laboratory and clinical work (Squadrito, 2017). In cosmetic use, Rejuran Healer is spread over the whole face for texture and dull, thin skin, Rejuran HB comes as a 1 cc syringe, and Rejuran Eye is a 1 cc dose kept to the thin skin under and around the eyes.
A systematic review of nine polynucleotide studies with 219 participants reported improvement in wrinkles, texture and elasticity with mild, short-lived side effects, while judging the studies low to moderate in quality and calling for stronger trials (Lampridou, 2024). At ENTER Plastic Surgery, numbing cream goes on for 30 minutes before Rejuran, and the plan is three sessions four weeks apart, then a top-up every three to six months. The clinic holds a REJURAN Official Certified Clinic plaque from PharmaResearch, the product maker.
Hyaluronic acid boosters: Skinvive, Belotero Revive and water glow
Hyaluronic acid binds water, and these boosters place it as very fine droplets in the upper skin layers for a hydrated, smoother surface. Skinvive comes as a 2 cc treatment. Here it is planned as one session, with a second one month later if your skin needs it, and repeat treatments come at six-month intervals; the clinic's guidance gives six to nine months for the result.
The water glow injection is a lighter hydrating treatment given with the Derma Shine injector. It is planned as three sessions four weeks apart, with three to six months as the clinic's figure for how long the effect lasts. Belotero Revive is a further hyaluronic acid booster on the menu, sold per 1 cc.
Collagen-building boosters: Juvelook Skin
Juvelook Skin uses poly-D,L-lactic acid, a material the body breaks down slowly while collagen forms around it, so changes appear gradually and not on the day. The 4 cc dose is delivered with Cure Jet, a needle-free injector. The course is three sessions four weeks apart, and the clinic's guidance puts the result at six to twelve months. Deeper volume products such as Sculptra, Radiesse and Juvelook Volume belong with the collagen stimulators, which have their own page.

Re2O, CellREDM, GOURI and Tissivo
These four are branded skin boosters listed by name on the clinic menu. Their ingredients are described in each maker's own product literature, which this page does not restate. Re2O is planned as three sessions four weeks apart, it can be given by needle or by cannula depending on skin type, and the clinic's figure for the result is six to twelve months. Re2O Fine appears on the price list as a separate item. For CellREDM, GOURI and Tissivo, the treatment plan is set when your skin is examined.
Exosome injections
Exosomes are extracellular vesicles, tiny particles that cells release to carry signals. A 2026 systematic review of extracellular vesicle treatments for facial rejuvenation found early signs of benefit and short-term safety, but the studies were small, followed patients briefly and used mixed methods, so no firm conclusion could be drawn (Gaebe, 2026). The clinic offers exosome in 1 cc and 4 cc amounts and uses the generic name on this site.
| Booster | Ingredient family | Aimed at | How it is given |
|---|---|---|---|
| Rejuran Healer, HB, Eye | Polynucleotide (PN) | Thin, dull or tired skin | Needle, after numbing cream |
| Skinvive | Hyaluronic acid | Dehydrated skin, fine surface lines | Fine needle, small droplets |
| Water glow | Hyaluronic acid | Surface hydration | Derma Shine injector |
| Belotero Revive | Hyaluronic acid | Hydration and skin quality | Needle |
| Juvelook Skin | Poly-D,L-lactic acid (PDLLA) | Gradual collagen building | Cure Jet, needle-free |
| Re2O | Per the maker's literature | Skin quality | Needle or cannula |
| Exosome | Extracellular vesicles | Skin quality (early evidence) | Injection, 1 cc or 4 cc |
When a skin booster should wait
- An active breakout, infection or cold sore in the area to be treated
- Pregnancy or breastfeeding
- A bleeding disorder, or blood thinners that have not been discussed first
- A known allergy to an ingredient or to the numbing cream
- A main concern of sagging or deep folds, which boosters are not designed to lift
The first days after the injections
Small raised bumps at the injection points flatten as the product absorbs over one to three days. Needle marks or bruises can stay for three to seven days, depending on the person. Keep water and makeup off the skin for three to four hours so the tiny punctures can close; makeup or concealer is fine from the next day. If anything unusual appears, such as spreading redness, heat or worsening pain, contact the clinic instead of treating it yourself.
Planning a booster visit from abroad
Because the clinic's guidance allows a flight home on the same day or the next day, a single booster session fits a short stay. A course of three sessions four weeks apart is a different plan: it either means returning to Seoul, or starting the course here and talking through the remaining sessions. ENTER Plastic Surgery is registered with Korea's Ministry of Health and Welfare as a medical institution for international patients (registration M-2023-01-08-7461).

Prices
What each skin booster costs in South Korea
The cards show the published price of each booster, and each one is listed before VAT; 10% VAT is added when you pay. Read the unit on each line, because the products are sold differently: Rejuran, Skinvive, Belotero Revive and exosome by the cc, CellREDM by the syringe, and Re2O, GOURI and Tissivo per session.
A course multiplies the per-session price, so a three-session Rejuran Healer plan is three visits at the listed fee. The glow package combines a 5 cc water glow injection with either glutathione or 2 cc of Juvelook in one visit. Ask for numbing cream and any combination of boosters to appear line by line in your written quote.

FAQ
Skin booster questions from international visitors
What is a skin booster?
A skin booster is an injectable treatment that places small amounts of a material such as polynucleotide, hyaluronic acid or poly-D,L-lactic acid into the skin. The goal is skin quality, meaning hydration, texture and firmness. It is not used to fill hollows or reshape the face the way a dermal filler is.
Can I go out the same day after a skin booster?
Yes, with small visible bumps for one to three days and possible needle marks or bruises for three to seven days. Avoid washing your face and wearing makeup for three to four hours afterwards. From the next day, makeup or concealer can cover any marks.
Can I fly home the day after a skin booster in Seoul?
Yes. The clinic's guidance is that flying home on the same day or the next day is possible after these injections. If you are planning a course of several sessions four weeks apart, decide before booking whether you will return to Seoul for the later sessions.
Who gives skin booster injections at ENTER Plastic Surgery?
Dr. Choi Yul, a family medicine specialist, focuses on Botox, injections and pigment treatment at ENTER Plastic Surgery. When you book, ask which doctor will give your booster injections.
Are the skin booster prices shown with VAT?
No. Each price is listed before VAT, and 10% VAT is added at payment. Prices are per cc, per syringe or per session depending on the product, so check the unit on each line and ask for a written quote that lists every product and the numbing cream.
Is Rejuran a filler?
No. Rejuran is a polynucleotide booster spread in small amounts through the skin to support its quality, and it does not lift or fill a fold. Hyaluronic acid fillers are a separate product group used for volume and contour, with their own page and prices.
What is glass skin treatment?
Glass skin is a beauty term for very smooth, even and well-hydrated skin, not a medical procedure. The treatments aimed at that look here are hydrating boosters such as water glow and Skinvive, and texture-focused boosters such as Rejuran. Results vary from person to person.
Is exosome treatment proven to work?
Not yet. A 2026 systematic review found early signs of benefit and short-term safety for extracellular vesicle treatments on the face, but the studies were too small and too short for a firm conclusion. The clinic lists exosome by its generic name in 1 cc and 4 cc amounts.
Do skin booster injections hurt?
Numbing cream is applied before the injections; for Rejuran it stays on for 30 minutes first. The sensation is a series of small pricks. Juvelook Skin is delivered with Cure Jet, a needle-free injector, which gives a different sensation from a needle.
How do I contact the clinic from outside Korea?
Send the form on this page or message us on WhatsApp with the boosters you are considering and your travel dates. English-speaking staff are available at the clinic. We will get back to you as soon as possible.
Is a deposit needed to book a skin booster?
Deposit and cancellation terms depend on the booking. Ask for both in writing before you pay anything, together with the exact products, amounts and units in your quote.

Great experience! Dr. is very sweet and kind. He listened to what I wanted to fix and correct. He explained everything very well. Wasn’t pushy and didn’t try to sell anything extra. This isn’t a clinic that comes out on instagram, which I…
I came to Enter Plastic Surgery on a friend’s recommendation for under-eye fat repositioning. I was pretty nervous going in, but the doctor took the time to explain what would work for my under-eyes, what the procedure involved, and what…
The staff are incredibly friendly, and the consultation was very thorough. I was very worried since it was my first procedure, but the director explained the aftercare in detail, so I felt completely confident trusting them!!
