Re2O: An ECM Booster, Not a Hydrator

Same family. The difference is our protocol: how we plan it, place it, and pace it. If the regular version suits you just as well, we’ll tell you. It’s a decision your doctor makes with you, not an upsell.

Usually a short series, because skin quality builds step by step. Your exact number depends on where your skin is starting from. 

Gradually, over the course, not the next morning. Boosters genuinely improve skin; they don’t mask it, so they take a little time.

The injections are quick and most people find them very manageable. You might have tiny marks for a day or so. We’ll walk you through it. 

Probably not on its own. Scars are structural. They need the Potenza treatment. Come in and we’ll tell you which one you’re actually dealing with.

Both work on skin quality rather than volume, but through different materials. Rejuran uses polynucleotide to support repair and texture. Re2O is an ECM booster, which replenishes the scaffolding of collagen and elastin that the skin builds on. The right one depends on whether your main issue is recovery and texture, or loss of structure. Your doctor will say which, and sometimes the answer is both in sequence.

No. A filler adds volume to a specific place and changes shape. Re2O changes the quality of the skin across an area and does not add contour. If your concern is a hollow, a filler is the honest answer. If it’s dull, slack or rough skin, a booster is.

Human acellular dermal matrix — hADM. It begins as donated human skin, processed to remove the cells and the components capable of provoking a reaction, leaving the structural material behind: collagen, elastin and the other proteins that form the matrix inside your skin. The manufacturer describes the product as 150mg of particulate acellular allogeneic dermis. It is processed by L&C Bio, a tissue bank, and supplied in Korea by Humedix under the name Elravie Re2O. The raw tissue is collected in the United States and Bulgaria. It reaches us as a powder and is mixed with saline immediately before your treatment.

One small human trial has been published. It is worth knowing what it tested: the formulation studied was Re2O mixed with a hyaluronic acid booster, saline and an anaesthetic, placed in the mid-dermis, against hyaluronic acid alone on the other side of the face. Serious adverse events were recorded as zero; what appeared was temporary redness and mild swelling that settled without treatment. The observation period ran about five months. The trial was small, one of its authors advised the manufacturer on product development, and the test article was supplied by the manufacturer. None of that makes it worthless — it makes it one small study rather than a settled answer.

Four things, and we would rather you asked them here than wondered afterwards. First, the exact product name and who makes and supplies it. Second, what else is going into the syringe today — hyaluronic acid, saline and an anaesthetic are commonly mixed in, and that changes what you are receiving from the pure product. Third, how many sessions and at what interval. Fourth, anything in your history that should postpone it: pregnancy or breastfeeding, active infection, autoimmune conditions, anticoagulants, severe allergy, or recent filler, toxin or laser on the same area.

No. They are different materials doing different jobs, and stacking them in one visit means neither you nor your doctor can tell what worked. They are sequenced instead, with the interval and order set at consultation.

It is regulated in Korea as human tissue, not as a medical device — and that distinction is worth understanding rather than glossing over. The tissue bank that processes it is approved by the Ministry of Food and Drug Safety, so the processing and donor screening sit under that oversight. The product itself does not go through the per-product efficacy review a medical device would. The same is true of the other human-matrix boosters in this family. Donor screening and processing records can be confirmed at your consultation, and you are welcome to ask to see them.

Yes — Re2O Fine. It is the same human dermal matrix milled to about 50 microns rather than the standard 100, because skin under the eye is only three to five tenths of a millimetre thick and a particle sized for the cheek can show through it or clump. The two are commonly planned in the same visit: Fine around the eyes, standard across the cheeks and forehead.
