RE2O SKIN BOOSTERThinner skin?
Refill the base.Instead of pushing your skin to make collagen,
it adds skin components that are already complete.

If your makeup no longer sits smoothly, fine lines are multiplying and your skin simply feels thinner than it used to, the supporting layer of the dermis is wearing down. Re2O (Elravie Re2O) is a skin booster made from human acellular dermal matrix (hADM) — donated human skin with the cells and fat removed, milled into a fine powder — that puts skin-building components such as collagen and elastin straight back into the dermis. We explain the raw material first, and a doctor examines your skin in person.

About Re2O

What is Re2O?

Re2O is a skin booster that replenishes the extracellular matrix (ECM) — the structure outside the cells that makes up the dermis. About 89% of it is collagen, together with elastin and hyaluronic acid. The powder is mixed with hyaluronic acid and injected into the dermis with a fine needle, usually in three sessions 3–4 weeks apart. It is made by L&C Bio, supplied by Humedix, and launched in Korea in November 2024.

Where it comes from

First, where the raw material comes from

Re2O is made from human skin. Donated skin tissue is processed by a licensed tissue bank, and the parts that can trigger an immune reaction, such as cells and fat, are removed so that only the skin's supporting structure remains. This human acellular dermal matrix (hADM) has long been used in surgery such as breast reconstruction and burn treatment; Re2O mills it finely enough to be injected.

01

Donated skin tissue

Skin obtained through human tissue donation is managed by a licensed tissue bank.

02

Cells and fat removed

The manufacturer's own process (AlloClean®) removes cells and components that can cause rejection while keeping the collagen structure.

03

Milled to a fine powder

Milled to an average of 100 µm or less, then mixed with hyaluronic acid right before injection.

How it works

Boosters that prompt vs. boosters that refill

Skin boosters work differently depending on what they put in. Rather than waiting for your skin to make new collagen, Re2O places skin-building components that are already formed right where they are needed.

STEP 1

Refills the base

Dermal structural components such as collagen and elastin go in directly and replenish the thinned dermis.

STEP 2

Acts as a scaffold

The matrix gives surrounding cells a framework to settle on, working together with your skin's own collagen formation.

STEP 3

Absorbed gradually

The injected material is absorbed slowly over time, which is why the plan builds up over several sessions spaced apart.

Evidence

What the clinical research says

There are still few randomized human studies on Re2O. Here is the main published study, with its limitations.

What concerns you most?

Even with the same Re2O, the plan changes with your concern. Pick what bothers you most right now and we will show how Dr. NewCell plans Re2O for it. The final plan is set together with the doctor after examining your skin in person.

For this concern · Re2O plan

Re2O base plan

Dermal structural components such as collagen and elastin go directly into the thinned dermis. Because the injected material is absorbed gradually, sessions are spaced apart and built up over time.

These are example plans by concern, not a diagnosis. The number and spacing of sessions and any combined treatments are decided in consultation after looking at your skin.

What sets them apart is what they put into the skin. The right booster depends on whether your skin has thinned, feels rough or is mainly dry.

Fill the base

Where skin has thinned,
start from the base

Rather than erasing fine lines one by one, we first look at where the dermis that supports your skin has thinned. The doctor decides how many sessions and what spacing suit you, based on your skin thickness and the care you are currently receiving.

Who it fits

Who Re2O suits — and when another option is better

Re2O tends to suit you if

  • your skin feels thinner and makeup often looks patchy
  • fine lines and loss of firmness both bother you
  • you have tried other skin boosters and wanted more change
  • you want to understand the raw material and classification before choosing

Consider another treatment first if

  • you would rather avoid human-derived material — we recommend medical-device skin boosters such as Rejuran or hyaluronic acid.
  • dryness is your main concern — a hyaluronic-acid water-glow type comes first.
  • sagging contours are the issue — a lifting consultation is a better fit than a skin booster.
  • you have depressed scars — the scar treatment Trifill PRO is the right choice.

Process

From explaining the material to planning sessions — all by the doctor

01

Direct doctor consultation

The doctor looks at your skin thickness, texture and dryness and decides whether Re2O or another booster suits you, explaining the raw material and classification at the same time. There is no separate consultation with a non-doctor coordinator.

02

Numbing cream

After cleansing, numbing cream is applied and left to work.

03

Injection into the dermis

Re2O mixed with hyaluronic acid is injected evenly into the dermis across the face with a fine needle.

04

Soothing · next session

We finish with soothing care and book the next session 3–4 weeks later.

FAQ

Frequently asked questions

What is Re2O?
It is a skin booster made by milling human acellular dermal matrix (hADM) — donated human skin with the cells and fat removed — mixing it with hyaluronic acid and injecting it into the dermis. It is about 89% collagen and also contains elastin and hyaluronic acid, so it directly refills the base components of thinning skin.
Re2O is made from human skin — is it safe?
Donated skin tissue is processed by a licensed tissue bank, and the manufacturer's process removes the cells and components that could cause rejection. Acellular dermal matrix has long been used in surgery such as breast reconstruction and burn treatment. However, Re2O is classified as a human tissue product rather than a medical device or drug, so it does not go through product approval, and Dr. NewCell explains this before treatment.
How is Re2O different from Rejuran?
Rejuran is a medical device using salmon-derived polynucleotides (PN) that support the skin's recovery environment, while Re2O is a human tissue product that directly puts in ready-made skin components such as collagen and elastin. If texture and damage are your main concern, Rejuran comes first; if your skin has thinned and fine lines have increased, Re2O is considered first.
How is Re2O different from Juvelook?
Juvelook is a medical device whose biodegradable polymer (PDLLA) stimulates the skin to produce collagen, while Re2O puts in the base components themselves, such as collagen. For firmness in hollow or dented areas Juvelook often fits; for skin that has thinned overall, Re2O often fits.
How many sessions, and how far apart?
A typical plan is three sessions 3–4 weeks apart, followed by a maintenance plan based on how your skin looks. The number and spacing of sessions are adjusted in consultation according to your skin thickness and goals.
When will I notice a difference?
Many people describe their skin feeling more hydrated and firmer from about 1–2 weeks, once needle marks and swelling have settled, and the change builds with each session. The Severance Hospital study measured results for 20 weeks after a single injection.
Does Re2O hurt? Will I get bumps?
We apply numbing cream first. The particles are fine and inject with little resistance, but it is a needle treatment, so there is some stinging. Needle marks, swelling and small bumps may appear and usually settle within 1–3 days.
Are there side effects?
Redness, swelling, bruising and temporary bumps may occur. No serious adverse events were reported in the published clinical study, but inflammation or nodules can rarely develop, so please contact the clinic straight away if anything seems wrong.
Can I combine it with Potenza or Botox?
They are often planned together: Potenza for pores and texture, Botox for expression lines and Re2O for the skin's base. Whether to do them on the same day or spaced apart is decided in consultation based on your skin.
How can I check it is genuine?
Re2O is a human tissue product whose tissue information is tracked for each unit. Before treatment we show you the unopened product and, if you wish, check the product information with you.
Can international patients consult and book?
Yes — English and Japanese consultations are available. Send photos by LINE or email before you fly and we will outline a session plan in advance; for short stays we plan the first session in Seoul and follow your progress after you return home.
