CellNutt My Second Skin Collagen

What is this product?

A dissolving nanofibre partial mask from CellNutt, supplied as forehead, cheek and under-eye pieces at 0.79g, 1.58g and 0.91g for five uses. The construction is the distinguishing fact and the ingredient order proves it: 하이드롤라이즈드콜라겐 at position 1 and 피브이에이 at 2 with 정제수 down at 6, meaning the sheet is made of its actives rather than soaked with them. Sixteen items, every level undisclosed, with 병풀추출물 at 12, 소듐히알루로네이트 at 13, 글루타치온 at 14 and 향료 at 16. No barrier lipid, no plant oil, no denatured alcohol, no acid and no notified functional active anywhere. The statutory table has no functional-cosmetic row at all, while marketing labels claim elasticity and fine-line benefit. The one quantitative result, a transepidermal water loss drop from 27.273 to 22.567 g/m2h by paired t-test, names no testing body, no subject count and no dates, and a companion image prints its three improvement rates as 0.000% with empty bars, which is an unreplaced template. Four separate companies appear in the record: shop operator, manufacturer, responsible distributor and consumer contact. Best for dehydrated skin wanting a short-contact hydration step; ruled out for anyone avoiding fragrance.

What makes it different?

One thing sets it apart inside partial masks and it is verifiable from the panel alone: the sheet is the formula. 하이드롤라이즈드콜라겐 at 1, 피브이에이 at 2 and 정제수 at 6 is the signature of a dry water-soluble film rather than an essence-soaked carrier, and it explains both the format benefits people report and the format's condition, namely that dissolution needs ambient moisture and leaves residue when there is not enough. Against that stands the evidence layer, and two defects are specific enough to name. The improvement-rate image prints 0.000% three times with empty after bars, an unreplaced template, and its own header scopes the test to the collagen nanofilm for reference rather than to the finished product. And the statutory table has no functional-cosmetic row at all, while the marketing prints elasticity and fine-line claims. The corollary for a reader is precise: trust the format and the hydration direction, and read the firming language as copy the brand's own legal disclosure does not cover.
