The efficacy score is driven mainly by niacinamide in the mid-to-upper part of the list, plus vitamin C derivative, salicylic acid, and a real brightening adjunct (phenylethyl resorcinol), but the formula does not look like a high-powered treatment because salicylic acid is buried low and the overall base is more cosmetic than corrective; the fragrance load and alcohol also reduce the safety score.
