The efficacy score of 3.8/5 reflects the clinically established 2% salicylic acid concentration in a leave-on serum, supported by a simple water-based vehicle and humectants including pentylene glycol, saccharide isomerate, and glycerin. The formula does not reveal its pH, so optimal BHA acidity cannot be confirmed; it also lacks additional evidence-backed acne-support ingredients such as azelaic acid or niacinamide. The marketed blemish benefit comes from salicylic acid itself, not from the basic supporting ingredients.
