Salicylic acid
It dissolves the gunk inside pores, which makes it decent for blackheads and smaller breakouts. It's milder than benzoyl peroxide, but the evidence behind it is thinner too, and dermatology guidelines back it with less confidence. If your skin can't handle benzoyl peroxide, a 0.5-2% salicylic acid wash is a reasonable plan B. Pick one acne treatment, not several: stacking them multiplies the irritation, not the results.
what the evidence says
FDA OTC monograph ingredient at 0.5-2%; conditional recommendation in the AAD 2024 guidelines (weaker evidence than benzoyl peroxide).
