The efficacy score is driven by a strong early-list humectant base, a meaningful niacinamide position, plus supported brightening actives like 3-O-ethyl ascorbic acid, ascorbic acid, arbutin, and multiple peptides; however, the formula is still a toner, so contact time and absolute active dose limit how hard it can perform compared with a leave-on serum.
