What is this product?

easydew's EGFx 다운타임 세럼 is a better recovery serum than its own branding suggests: the 40ml formula carries Ceramide NP with cholesterol and stearic acid at 40, 42 and 44, which is the full barrier lipid set most competitors do not assemble, plus ectoine, beta-glucan and a nicotinamide mononucleotide and ATP energy group. The EGF the line is named after is disclosed at 1ppm and sits 34th of 55, so it is the least of what you are buying. Fragrance-free, but ethanol is printed 19th, higher than most calming serums put it, which can sting on a barrier that was just treated. easydew does publish numbers for it, EGFx at 83% and three 5-minute soothing figures (24%, 8.4%, 5.2%), but none names an entry on the statutory list or comes with a participant count, an institution or a defined endpoint, and no pH is given.

What makes it different?

Two things are genuinely uncommon here. First, a ferment filtrate is printed first, ahead of water at 4th, which is a real formulation decision rather than a label flourish. Second, the brand prints an amount for its hero peptide, sh-Oligopeptide-1 at 1ppm, where most growth-factor products disclose nothing. The lipid set is the other differentiator: ceramide, cholesterol and a free fatty acid together, rather than a lone ceramide, which is the combination barrier-repair research actually tests. What is missing is checkable measurement rather than measurement as such. easydew publishes an 83% EGFx content figure and three 5-minute soothing percentages for this serum, but EGFx is not an entry on the statutory list and the soothing figures carry no participant count, institution or defined endpoint, so every verdict here still rests on ingredient literature. The sting risk from ethanol at 19 is the one thing recently treated skin should weigh.

Ingredients with no mark are ones we found nothing notable about, and when marks overlap on one ingredient we show the caution first.
