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
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
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.
Skin obtained through human tissue donation is managed by a licensed tissue bank.
The manufacturer's own process (AlloClean®) removes cells and components that can cause rejection while keeping the collagen structure.
Milled to an average of 100 µm or less, then mixed with hyaluronic acid right before injection.
How it works
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.

Dermal structural components such as collagen and elastin go in directly and replenish the thinned dermis.
The matrix gives surrounding cells a framework to settle on, working together with your skin's own collagen formation.
The injected material is absorbed slowly over time, which is why the plan builds up over several sessions spaced apart.
Evidence
There are still few randomized human studies on Re2O. Here is the main published study, with its limitations.

Find yours
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.
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.
Refilling the dermal baseSee how it works →We refill the thinned base of the skin while looking at fine lines and firmness together. From about 1–2 weeks the skin starts to feel hydrated and firmer, and a maintenance plan is set after the third session.
Fine lines · firmnessSee what to expect →Instead of waiting for your skin to make new collagen, Re2O places skin-building components that are already formed right where they are needed. In consultation we plan it around your past treatments and current skin.
Boosters that prompt vs. boosters that refillCompare with other boosters →We often plan Potenza to refine pores and texture together with Re2O to refill the skin's base. Whether to combine them is decided after looking at your skin.
Pores · texture + thin skinSee combinations →Expression lines caused by movement are treated with Botox, and texture and fine lines with Re2O.
Expression lines + fine linesSee combinations →Contours are handled with lifting and the skin's base with Re2O, planned separately. Lifting comes first, and Re2O follows on a later schedule.
Sagging + thin skinSee combinations →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.
Compare
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
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.

Process

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.
After cleansing, numbing cream is applied and left to work.
Re2O mixed with hyaluronic acid is injected evenly into the dermis across the face with a fine needle.
We finish with soothing care and book the next session 3–4 weeks later.
After Re2O
There may be needle marks and mild swelling or redness, which usually settle within 1–3 days.
Marks fade and your skin starts to feel hydrated and firmer.
The next session builds up the base components further.
The next treatment is timed to your skin; the interval differs from person to person.
Combination
Skin boosters are often planned alongside Potenza for pores and texture. Whether to add Re2O depends on your skin.
Lines caused by movement are treated with Botox; texture and fine lines with a skin booster.
Contours are handled with lifting such as XERF, and the skin's base with a skin booster.
