System Verdict
This is a solid antioxidant cocktail with a gentle hydrating base, but its vitamin C derivative and peptide mix make it more of a nice support serum than a heavy‑hitting treatment. Efficacy hinges on mid‑list ascorbyl glucoside and several well‑studied antioxidants (ergothioneine, epigallocatechin, tocotrienols, ginseng) plus humectants, but the use of a relatively mild vitamin C derivative at unknown concentration and boutique peptides in supporting positions keeps this in the moderate, prevention/maintenance range rather than a high‑impact brightening or firming serum.
