The efficacy score is held back by heavy early-position alcohol, a fragrance load, and the fact that the strongest treatment ingredients are mid- to low-list rather than dominant; the vitamin C derivatives and peptides add real but modest support, while the exfoliating acids and many of the “rare” ingredients are likely too low or too unfocused to drive a clinically strong result.
