Re2O, sold as Elravie Re2O, is a skin booster made from micronized acellular dermal matrix: donated human skin tissue with the cells removed, leaving the collagen framework of the dermis. At ENTER Plastic Surgery in Seoul, each Re2O skin booster session takes 20–30 minutes under numbing cream, given by needle or cannula to suit your skin, and the plan is three sessions four weeks apart.

Is it for you?
Who the Re2O skin booster suits
Re2O belongs to the group of injectables aimed at skin quality: how dense, smooth and well hydrated the skin looks and feels. It is placed in the dermis, the layer under the surface that thins with age and sun exposure, and the matrix is meant to act as a framework that the skin's own repair cells can work on. That makes it a fit for texture and fine crepiness across the face, where a volumizing filler would sit heavy.
It is a poor match for structural problems. Deep folds come from lost volume, and loose skin along the jaw comes from laxity, so those point to fillers, collagen stimulators or lifting. Because Re2O is derived from donated human tissue, it is also worth deciding before the consultation whether you are comfortable with that origin; other boosters on the menu use different ingredients, listed in the comparison table below.
Usually a good fit
- Dull, rough or uneven skin texture
- Fine, crepey lines and thinning skin
- Wanting a booster for skin quality, not volume
- Able to come back for 3 sessions, 4 weeks apart
- Areas where a filler would look heavy
We may suggest waiting
- Deep folds or jowls that need volume or lifting
- Active acne, infection or inflammation on the face
- Pregnancy or breastfeeding
- Not wanting a human tissue-derived product
- An important event within the next few days
How it works
How Re2O works in the dermis
Elravie Re2O comes from L&C BIO, a Korean company. The starting material is donated human dermis that has been decellularized, meaning the cells are removed so that what remains is the extracellular matrix: collagen, elastin and the other structural proteins that hold the dermis together. That matrix is then broken into fine particles that can pass through a needle or cannula. Once injected, the particles are intended to work as a scaffold and a signal, giving fibroblasts, the skin's collagen-making cells, a framework to grow into.
The clinical research uses dermal matrix products in general, and the trials below do not name Re2O, so they describe the material class. In a split-face, double-blind trial, a particulated human acellular dermal matrix booster improved skin density, elasticity, wrinkles and hydration more than a hyaluronic acid control, with no serious adverse events (Lee, 2026). In a multicenter randomized trial for nasolabial folds, a micronized dermal matrix injection was non-inferior to a collagen filler using less volume, though early swelling and pain were slightly more common and cleared within a week (Zhang, 2025).
Reading your skin
At consultationSkin thickness, texture and the areas of concern decide where Re2O is placed and whether a fine needle or a blunt cannula suits your skin.
Numbing
Numbing cream goes on the face and is left until the surface is numb, so the injections feel like light pricks or pressure.
Placing the matrix
20–30 minutesWith a needle, Re2O is laid down as many tiny deposits; with a cannula, it is fanned under the skin from a few entry points.
Sessions two and three
Every 4 weeksThe second and third sessions follow at four-week intervals, building on the framework placed in the first.

Prices
Re2O injection prices in South Korea
The clinic's list has two Re2O lines, each charged per session: Re2O at ₩1,200,000 and Re2O Fine at ₩800,000. Neither figure includes tax; Korea's 10% VAT is added when you pay. The starting plan is three sessions, so a first course is three session fees of whichever line your plan uses.
The clinic's materials do not set out how Re2O Fine differs from standard Re2O. When you request a quote, ask which line is planned for your skin and for the course total to be written out.
Prices exclude VAT (10% VAT is added at payment).
Recovery
Re2O recovery after each session
Raised blebs or small cannula entry marks are visible as you leave. Keep water and makeup off the treated skin for three to four hours while the needle openings close.
Concealer and makeup can go on. Flying home the same day or the next day fits the clinic's guidance, so a short stay is enough for one session.
The blebs flatten as the material is absorbed over one to three days. Avoid pressing or rubbing them while they settle.
Bruises or needle marks fade over three to seven days, depending on your skin. If pain, heat or redness grows, contact the clinic instead of treating it yourself.
The second of three sessions is due, followed by the third four weeks later.
Safety
Re2O side effects and limits of the evidence
Any injection into facial skin carries short-term reactions, and a product built from human tissue adds the question of how your body responds to it. A review of skin-rejuvenating mesotherapy, the broad family of injections into the dermis for skin quality, found no clinically valuable new evidence over a decade and advised against routine use until conclusive data arrive (Atiyeh, 2021).
- Swelling, redness and raised bumps for one to three days.
- Bruising or needle marks lasting three to seven days.
- Small lumps or uneven texture if the material gathers in one spot.
- Infection at needle or cannula entry points.
- A reaction to the injected material, such as prolonged redness or a firm nodule.
- With any facial injection, a rare blockage of a blood vessel; pain that spreads or skin that turns pale or dusky needs urgent attention.
The trials on dermal matrix boosters are short and small, and none tested Re2O by name, so the evidence supports trying the treatment with modest expectations.

FAQ
Re2O skin booster FAQ
What is the Re2O skin booster?
Re2O is an injectable skin booster made from micronized acellular dermal matrix, which is processed human dermis with the cells removed. It is placed in the dermis to support skin density, texture and hydration, and it is planned as three sessions four weeks apart at ENTER Plastic Surgery.
How much does Re2O cost in Korea?
Re2O is ₩1,200,000 + VAT per session and Re2O Fine is ₩800,000 + VAT per session. The listed fees exclude VAT, and 10% is added at payment. With a three-session starting plan, budget three session fees for the first course.
What is Re2O Fine?
Re2O Fine is a separate line on the clinic's price list, charged per session like standard Re2O. The clinic's materials do not describe how the two versions differ, so ask which one is planned for your skin, and why, when you request your quote.
Is Re2O made from human tissue?
Yes. Re2O is derived from donated human dermis that has been decellularized, so the cells are removed and the structural matrix remains. If you prefer to avoid human tissue-derived products, say so at the start; the clinic's menu also lists hyaluronic acid and polynucleotide boosters.
How many Re2O sessions do I need?
The clinic plans three sessions, four weeks apart. Each session adds to the framework placed in the one before, which is why the interval is kept. Because the course runs about eight weeks from first to last session, visitors from abroad may need to plan more than one trip.
How long does Re2O last?
The clinic's guidance is six to twelve months after the course. Skin type, age, sun exposure and smoking all affect how long the change holds, and a maintenance session can be planned once the effect starts to fade.
Is Re2O injected with a needle or a cannula?
Either. The clinic chooses a fine needle or a blunt cannula to suit your skin type. Both start after numbing cream, a topical anaesthetic (the UK spelling of anesthetic). A needle leaves small raised blebs, while a cannula uses a few entry points and spreads the product beneath them.
What is the downtime after Re2O?
Short. The raised blebs absorb within one to three days, and needle marks or bruises can last three to seven days depending on your skin. Avoid washing or makeup for three to four hours after the session; from the next day, concealer can cover the marks.
Can I fly home right after a Re2O session?
Yes, the clinic's guidance allows flying the same day or the next day. Bring concealer for visible marks and avoid rubbing the treated skin during the flight. The remaining sessions are four weeks apart, so plan return visits around that interval.
Who gives Re2O injections at ENTER Plastic Surgery?
The clinic does not publish a single injector for skin boosters. Its two named doctors are Dr. Jang Jin-woo, a Korean board-certified plastic surgeon, and Dr. Choi Yul, a family medicine specialist whose focus is injections and pigment care. Ask whose appointment you have when you book.
How do I book Re2O from abroad?
Use the form on this page or message us on WhatsApp with your travel dates and skin concerns, and we will get back to you as soon as possible. English-speaking staff are available at the clinic, and three sessions four weeks apart can be planned around your trips.
Do I need to pay a deposit to book?
Deposit and cancellation terms differ by booking, so get them in writing before you transfer money. With a three-session course, check how the terms apply to each session, since moving one visit can shift the dates of the next.

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!!
