CellREDM: the same hADM idea, ground finer

In this class, particle size is not a specification detail. It determines where the product can be used at all.

Resistance on injection rises with particle size, and two consequences follow. First, more force is needed and the treatment hurts more. Second, product tends to collect rather than distribute. Neither matters much in thick skin. In periorbital skin, both show.

CellREDM addresses this by milling the matrix to approximately 75 μm. Lower injection resistance and less clumping make thin, reactive areas more approachable.

The raw material deserves stating plainly: CellREDM begins with donated human skin. A good deal of promotional material avoids saying so. We would rather you knew and chose.

What is injected is not skin. Donated tissue undergoes decellularisation — detergents, enzymes, repeated freeze-thaw — which removes cells, cellular debris, and the cell-surface antigens and DNA that would otherwise provoke an immune response. What remains is the scaffold: collagen types I and III, elastin, and the glycosaminoglycans that bind water.

This material was not invented for aesthetics. It has a long history in severe burn reconstruction and breast reconstruction, where a surgeon needs a scaffold the body can build into. Products like CellREDM take that same material, reduce it to fine particles, and make it injectable.

Our Re2O reference covers the composition and processing of hADM at greater length.

Miso Clinic stocks both hADM products. They share a goal, so the choice comes down to site and skin thickness.

Being straightforward about it: no study has compared the two products directly. There is no basis for calling either superior. We stock both because a clinic holding one product ends up using that product everywhere.

Six collagen boosters compared — which one fits →

Comparison charts tend to list product names. The distinction that matters is simpler: does the product ask the skin to do the work, or does it supply the material?

Reasonable candidates

• Thin periorbital skin where fine lines and density are the main concern
• Patients who found that other boosters left visible injection points or a lumpy feel
• Skin that feels thin and structurally weak overall
• Skin made reactive by repeated laser or energy-based treatment
• Patients who want to avoid the nodule risk of stimulator-class products

Where CellREDM alone will not get you there

• Hollowing of the cheeks or temples — hADM creates no volume
• A softening jawline — lifting devices or collagen stimulators
• Deep dynamic lines — botulinum toxin or filler
• Pregnancy or breastfeeding, or active infection at the treatment site
• Discomfort with a human-derived material — an entirely reasonable position, and one we can plan around completely

Worth setting out plainly.

Acellular dermal matrix as a material has a long record in burn and breast reconstruction, and the principle that removing cells and antigens lowers immune-rejection risk is well established in biomaterials.

However, we found no published clinical trial data specific to CellREDM as a product. Research on injectable hADM generally remains small in scale and short in follow-up. For that reason this page makes no claim about months of duration or a required number of sessions — it is better not to state as settled what has not been settled.

The consultation begins by separating density from volume. If hADM is appropriate, site and skin thickness decide which of the two products we use. We always explain the human-derived origin before treatment; if that is not something you are comfortable with, we plan differently.

Topical anaesthetic is applied for 20–30 minutes, then the product is placed into the dermis through a fine needle at many separate points, small volumes closely spaced.

Immediately afterwards each injection point sits slightly raised — product resting in the dermis, which settles as it is absorbed.

Most patients return to normal activity the same day. Injection marks may not be fully concealable for a day or two, so allow two or three days before anything important.

• Cleanse gently with lukewarm water on the day; do not rub the treated area
• Avoid sauna, jjimjilbang, strenuous exercise and alcohol for the first day
• Use sun protection diligently
• Resume makeup when your clinician advises

This reference was written and reviewed by Dr. Lee Chi-Hak, director of Miso Clinic in Daegu, South Korea. The clinic stocks six collagen boosters and skin boosters with genuinely different active materials — liquid PCL (GOURI), PN (Rejuran), hADM (Re2O, CellREDM) and CaHA (Radiesse, DCLASSY) — and selects between them according to which kind of ageing the face is actually showing. A clinic holding one product will use that product. See our comparison of all six and the references on liquid PCL, polynucleotide, hADM, DCLASSY and Radiesse.
