Re2O Skin Boosterin Gangnam, Seoul
Re2O is an injectable skin booster that supplies extracellular-matrix (ECM) components — mainly collagen, along with elastin and hyaluronic acid — directly into the dermis to support the skin’s structural foundation. At QD Clinic in Gangnam, Seoul, South Korea, we assess your skin first, then decide the areas to treat and the amount to use. A session usually takes about 20–40 minutes including numbing, with little downtime. (Results vary by individual.)
Who it’s for
- Dull, thin or crepey skin that has lost firmness
- Those who want to support the skin’s structure, not only hydrate the surface
- Uneven texture or shallow depressed scars
- Anyone comparing next-generation boosters after trying other options
Suitability, treatment areas and the right number of sessions are confirmed during consultation.
How it works
Re2O is often described as a fourth-generation, ECM-based booster. Rather than only prompting the skin to make new collagen, it delivers ready-made extracellular-matrix material — mainly collagen, with elastin, hyaluronic acid and other ECM components derived from human-tissue matrix — into the dermis, where it acts as a scaffold that supports dermal structure and remodeling over the following weeks. It is placed with fine microinjections across the treatment area. This differs from polynucleotide boosters such as Rejuran, which support the skin’s own repair, and from PDLLA boosters such as Juvelook, which prompt collagen renewal.
THE MECHANISM, STEP BY STEP
01Ready-made matrix, not just a signal
Rather than only prompting the skin to make new collagen, Re2O delivers extracellular-matrix material — mainly collagen, with elastin and hyaluronic acid — directly into the dermis.
02A scaffold in the dermis
The ECM components act as a supportive scaffold within the dermis, where the skin’s own cells can organize and remodel over the following weeks.
03Placed with fine microinjections
Fine microinjections distribute the material evenly across the treatment area, at the depth chosen for your skin.
04Why change is gradual
Because remodeling follows the skin’s own timeline, firmness and texture develop over weeks rather than immediately. (Results vary by individual.)
Treatment areas
- Full face
- Overall skin quality, firmness and texture.
- Under-eye & cheeks
- Thin, crepey areas that benefit from structural support.
- Neck
- For fine lines and loss of firmness on the neck.
- Depressed scars
- Shallow, atrophic scars decided at consultation.
What the procedure is like
- 1Consultation and skin assessment
- 2Cleansing and numbing cream
- 3Microinjections across the treatment area
- 4Cooling, soothing and aftercare guidance
Time: A session takes about 20–40 minutes, including numbing time.
Recovery & aftercare
- Little downtime; small raised bumps at the injection sites may appear and usually settle within about 2–3 days.
- Temporary redness, mild swelling, tenderness or minor bruising may occur.
- Avoid saunas, heat and intense exercise briefly, use sun protection, and follow the soothing guidance we provide.
What to expect over time
A general guide to how the days and months after treatment usually unfold. Results vary by individual.
DAY 0 Treatment day
Numbing first, then microinjections. Small raised bumps, mild redness or a flushed feeling may appear at the injection sites.
DAY 1-3 Bumps settling
The small bumps and any swelling usually soften and settle. Minor bruising, if any, begins to fade.
WEEK 1-4 Early remodeling
The skin begins to work with the delivered matrix. Changes at this stage are subtle and vary between people.
4-8 WEEKS Skin-quality change
As the dermis remodels, many people notice firmer, smoother-looking skin. This is typically when results are assessed. (Results vary by individual.)
AFTER THE COURSE Review & maintenance
Your doctor reviews the outcome and discusses timing for any maintenance session based on your skin.
Sessions & results
A typical plan is a short course of about 2–3 sessions spaced roughly 4–6 weeks apart, with changes developing gradually over about 4–8 weeks as the skin remodels. A maintenance session may be considered after a period decided at consultation. (Results vary by individual.)
How it compares
These injectable skin boosters all support skin quality, but they use different materials and work in different ways, so they suit different goals.
| Comparison | Re2O | Rejuran | Juvelook |
|---|---|---|---|
| Main agent | ECM components (collagen, elastin, HA) | Polynucleotides (from salmon DNA) | PDLLA microparticles + HA |
| How it works | Supplies ready-made matrix as a scaffold | Supports the skin’s own repair | Prompts gradual collagen renewal |
| Often chosen for | Structural support, thin or crepey skin | Overall skin quality, fine lines | Texture, glow and subtle structure |
| Sessions | Usually a short course | Usually a course of a few sessions | Usually a short course |
| Downtime | Little; small bumps possible | Little; small bumps possible | Little; small papules possible |
Neither is “better” — they work differently and suit different goals. The right choice is decided after we assess your skin.
Safety & considerations
Possible reactions
- Temporary redness, a flushed feeling, or mild swelling at the injection sites
- Small raised bumps or papules that usually settle within a few days
- Tenderness or a tight feeling in the treated area for a short time
- Occasionally minor bruising at injection points
When to take extra care
- Pregnancy or breastfeeding — let us know at consultation
- Active skin infection, inflammation or open lesions in the treatment area
- Known allergy or hypersensitivity to any component of the product
- A history of keloid or difficulty with wound healing
- Recent injectables or energy treatments in the area — tell your doctor so timing can be planned
Whether Re2O suits your skin is confirmed during consultation, and it is not suitable for everyone. Effects develop gradually and vary by individual, and side effects may occur.

Frequently asked questions
Re2O is an injectable skin booster often described as a fourth-generation, ECM-based booster. It supplies extracellular-matrix components, mainly collagen along with elastin and hyaluronic acid, directly into the dermis. There they act as a scaffold that supports the skin's structure and remodeling over the following weeks.
It is most often used across the whole face for skin texture and firmness, and also on thin, crepey areas such as under the eyes and the cheeks, and on fine neck lines. It is sometimes used for shallow atrophic scars, but depending on a scar's depth and shape it may not suit, so this is decided at your examination. The depth and amount are set for each area and placed in small portions with fine microinjections.
Yes. Its ECM components come from human-tissue-derived matrix that is processed to remove cellular material. Before treatment we go through the product details with you, and you should mention any known allergy or hypersensitivity to its components.
A numbing cream is applied first, and the whole session, including numbing, usually takes about 20–40 minutes. Some pressure or brief stinging may still be felt during the microinjections. If you are sensitive, tell us beforehand so we can adjust the pace.
Many people have a short course of two to three sessions spaced four to six weeks apart. The change appears gradually over four to eight weeks as the skin regenerates, so we review your progress between sessions before setting the next one. Maintenance after the course can be considered once an agreed interval has passed.
Small marks and mild swelling appear where the injections were placed, and they usually settle within one to three days. Some people bruise, so if you have an important occasion coming up it is better to allow about a week. On the day of the treatment, please avoid saunas, strenuous exercise and alcohol.
The mechanism differs. Re2O supplies ready-made ECM material, Rejuran uses polynucleotides to support the skin’s own repair, and Juvelook uses PDLLA to prompt collagen. The right choice is decided after we assess your skin.
We first check whether assessment and any necessary follow-up fit your stay. Share your arrival, departure and important event dates before booking. For this treatment, the expected course is as follows. A typical plan is a short course of about 2–3 sessions spaced roughly 4–6 weeks apart, with changes developing gradually over about 4–8 weeks as the skin remodels. A maintenance session may be considered after a period decided at consultation. (Results vary by individual.) Temporary redness, mild swelling, tenderness or minor bruising may occur. Avoid saunas, heat and intense exercise briefly, use sun protection, and follow the soothing guidance we provide. Examination may lead to postponement or additional visits. Confirm contact arrangements after returning home and when in-person medical care may be needed. What the doctor checks first for this treatment: “Skin showing dryness, rough texture and loss of elasticity together”.
Often considered together
Treatments that are sometimes planned alongside this one, decided at consultation.
+Ultrasound or RF lifting
Energy-based lifting addresses laxity and deeper support, which boosters do not target — sometimes planned together for skin quality plus firmness. Sequencing is decided by your doctor.
+Botulinum toxin
For dynamic lines from muscle movement (forehead, frown, crow’s feet), often planned alongside skin-quality treatments for a balanced result.
+Tone-focused treatments
Pigment or redness concerns are addressed by other treatments, which can be combined with booster sessions in a plan decided at consultation.
