Short answer: salicylic acid is commonly chosen for clogged pores, blackheads and whiteheads, while benzoyl peroxide is often useful for red, inflamed pimples. One is not universally better than the other.
What does salicylic acid do?
Salicylic acid is a beta-hydroxy acid that helps exfoliate inside pores. It is often used when congestion, blackheads and small clogged bumps are the main problem.
It can still dry or irritate the skin, especially if you combine it with several other strong products at once.
What does benzoyl peroxide do?
Benzoyl peroxide helps reduce acne-causing bacteria and inflammation, which is why it is commonly used for inflamed pimples. Higher strength is not automatically better; irritation can make people abandon treatment.
One practical note: benzoyl peroxide can bleach towels, pillowcases and clothing.
Can you use both?
Some acne routines use both, but starting multiple active ingredients on the same day can make it hard to know what is helping and what is irritating you. Introduce products carefully and follow the product directions.
If you use prescription acne treatment, ask the prescribing clinician before changing the routine.
What if neither one is working?
Persistent acne may need a different diagnosis or treatment plan. Deep painful acne, scarring or significant pigment changes are good reasons to see a physician or dermatologist rather than continually adding stronger over-the-counter products.
