Re2o is an ECM skin-quality booster that delivers collagen, elastin, and hyaluronic acid into the dermis, refining firmness and glow over about 3 sessions.
Re2o is an extracellular-matrix (ECM) skin-quality booster that micro-injects native dermal building blocks, mainly collagen with elastin and hyaluronic acid, into the dermis. It strengthens the skin’s own structure to improve firmness, elasticity, pore texture, and a dewy tone over a course of about three sessions, rather than adding contour volume like a filler.
One-on-One guidance from a dedicated doctor, ensuring your skin is professionally monitored and treated from start to finish.
Fluent assistance in English, Japanese, and Chinese, making communication clear, respectful and comfortable for international patients.
Over 100,000 patients worldwide have received our personalized dermatological care, highlighting our expertise and reliable results.
Re2o is a skin-quality booster built on the extracellular matrix (ECM), the natural scaffold that holds skin cells together. Rather than a single ingredient, it delivers a blend of dermal building blocks, predominantly collagen alongside elastin and hyaluronic acid, into the dermis to reinforce the skin’s structural foundation. It is best understood as a skin-quality and texture treatment, not a contour filler and not an exosome therapy.
By restoring ECM components where they naturally sit, Re2o supports firmness, elasticity, pore refinement, and an even, dewy tone from within. Because it works by reinforcing structure and signalling repair rather than physically lifting tissue, results build progressively, with many patients noticing improvement after a single session and the fullest effect across a short course. A typical plan is about three sessions spaced two to four weeks apart, with periodic maintenance.
Re2o rose to popularity in Korea from 2025 and is a frequent reason international patients visit Seoul. Reberry Clinic serves visitors across three Seoul-area locations (Gangnam, Myeongdong, Incheon Airport), with English-language consultation and treatment planned and reviewed by the clinic’s doctors.
Re2o works by replenishing extracellular-matrix components directly into the dermis. The matrix that gives skin its strength and bounce is roughly collagen-dominant, with smaller proportions of elastin and glycosaminoglycans such as hyaluronic acid; as skin ages, these decline. Re2o supplies these native building blocks where they belong, acting as a biocompatible scaffold that supports fibroblast activity and helps the skin hold moisture and rebuild firmness. The approach is regenerative and structural rather than volumising, which is why Re2o is grouped with skin-quality boosters used for glass-skin goals rather than with hyaluronic acid contour fillers or neuromodulators, and why its benefits accumulate over weeks instead of appearing as instant volume.

The clinic’s doctors review your skin quality and plan an injection map, typically across 1 full-face session per visit.
Topical anaesthetic is applied for about 20 to 30 minutes so the micro-injections are comfortable.
The ECM booster is placed into the dermis through many fine injection points, usually completed in about 15 to 20 minutes.
Over the following 2 to 4 weeks, the replenished matrix supports fibroblasts and the skin holds more moisture.
A typical plan is about 3 sessions spaced 2 to 4 weeks apart, with results compounding through the course.

The clinic’s doctors assess your skin quality, discuss goals, and recommend how many sessions suit you, explained in English.
After numbing, the micro-injection session itself takes about 15 to 20 minutes, with the visit lasting under an hour.
A full plan is usually about 3 sessions spaced 2 to 4 weeks apart, with optional maintenance later.
Firmness and tone improve gradually over weeks, often with a noticeable change after the first session and the fullest effect after the course.
Effects often last several months; gentle skincare, sun protection, and periodic top-ups help maintain them.
Re2o is an extracellular-matrix (ECM) skin-quality booster that delivers collagen, elastin, and hyaluronic acid into the dermis to strengthen the skin’s structure. It improves firmness, pore texture, and dewy tone rather than adding contour volume. You can see how it fits a glass-skin plan on our glass-skin booster page.
No, Re2o is an ECM booster built on structural matrix components such as collagen, elastin, and hyaluronic acid, not an exosome therapy. The two work through different mechanisms even though both aim at skin quality. A consultation explains which approach suits your goals, and our glass-skin page outlines the booster options available.
No, Re2o is a skin-quality booster, not a volumising contour filler. It reinforces the dermis to improve firmness and texture rather than reshaping facial contours. If your goal is to add structural volume to cheeks or chin instead, our injectable fillers page explains how hyaluronic acid contour fillers differ.
Adults wanting firmer, smoother, more even-toned skin, especially those with mild laxity, enlarged pores, or dull tone, are ideal candidates. It suits people seeking a structural, natural-looking improvement. A consultation confirms suitability and rules out allergy. Skin that is currently inflamed or infected should be treated first.
Most patients describe mild stinging during the micro-injections, which is well managed with topical numbing applied for 20 to 30 minutes beforehand. The injections take only about 15 to 20 minutes. Any discomfort is brief, and fine needles are used to keep the experience comfortable throughout the session.
Downtime is minimal: expect tiny raised bumps at injection points plus mild redness for one to two days as the product settles. Some light bruising can occur but is usually minor. Most international visitors continue light sightseeing the next day and can cover any redness with gentle makeup.
Re2o works gradually, but many patients notice firmer, more refined skin after the first session, with the fuller effect building over several weeks as the matrix integrates. Skin-booster studies measured significant hydration gains across a three-session course. Results are progressive and compound through the plan rather than appearing as instant volume.
A typical Re2o plan is about three sessions spaced two to four weeks apart, allowing the structural effect to compound. Some patients with more pronounced laxity or texture concerns benefit from additional sessions. Your doctor recommends the right number at consultation based on your skin condition and goals.
Results commonly last several months, after which periodic maintenance helps sustain the improvement. Because Re2o reinforces your own skin structure, natural ageing continues over time. Many patients schedule a top-up every few months. Pairing it with a good skin care routine helps extend the benefit you achieve.
Yes, Re2o is frequently combined with lasers, energy lifting, or other boosters, sequenced safely by your doctor for complementary effects. Many patients pair it with a regenerative booster for added repair. You can read about a polynucleotide alternative on our Rejuran Healer page to understand how they differ.
Re2o has a favourable safety profile, with structural ECM components used as a biocompatible scaffold and clinical studies reporting no serious adverse events. Side effects are usually limited to temporary redness, swelling, or small bumps. Serious reactions are rare. Your doctor reviews your history to keep the treatment safe and appropriate for you.
Expect temporary redness, minor swelling, small bumps at injection points, and occasional light bruising for a day or two. These resolve on their own. Less common reactions include tenderness or transient itching. Serious complications are rare when an experienced doctor performs the injections using appropriate technique and sterile conditions.
Aftercare is simple: keep the area clean, avoid makeup for the rest of the day, and skip saunas, intense exercise, and alcohol for a couple of days. Protect skin from sun and stay hydrated. Your clinic provides written aftercare so you can follow it confidently once you travel home.
For a single session you need only one to two days, covering consultation and treatment with minimal downtime. If you want to complete part of a course, your team can schedule sessions across a longer stay or plan follow-ups for a return trip. Our English team coordinates timing around your travel.
Yes, flying soon after Re2o is generally fine, often the next day, because it is a minimally invasive injectable with only minor swelling. Stay hydrated during the flight and avoid touching or pressing the treated skin. If you had extensive treatment, your doctor will advise any specific timing before you travel.
International patients can have remote check-ins in English after returning home, with progress reviewed as results develop over the weeks. If you want to continue your course or add care later, you can explore related options such as glass-skin boosters. Your treatment notes are kept on file for any future visit.
