Understanding the Acne Actives: BHA vs Oxygen
Salicylic Acid is a oil-soluble Beta Hydroxy Acid (BHA) that penetrates deep into pores to dissolve sebum and dead skin cells. It is the best active for treating blackheads, whiteheads, and general skin congestion.
Benzoyl Peroxide (BPO) works by introducing oxygen into the pores to kill the acne-causing bacteria on contact. It is highly effective for painful, red inflammatory acne pimples.
Can You Use Both Salicylic Acid and BPO Together?
Using both in the same step can dry out your skin and cause severe peeling. Instead, use a salicylic acid face wash in the morning to keep your pores clean, and apply a benzoyl peroxide gel as a spot treatment at night.
