Salicylic acid, a popular BHA, effectively treats acne by exfoliating pores, reducing oil, and calming inflammation. Dermatologists recommend it for clearing blackheads and preventing breakouts. Found in various skincare products, it delivers results in 4-6 weeks. While generally safe, it can cause dryness and sun sensitivity. Experts advise starting with low concentrations and avoiding combining it with other exfoliants.
