Salicylic acid + benzoyl peroxide
What the sources say
CeraVe says these two acne actives are generally best used on their own, that using them together may raise the risk of skin irritation, and that a dermatologist may combine them in a planned way for stubborn or severe acne. Healthline says they should not be used together on the same area of skin. Both are consumer health sources. We have not tested this pair ourselves.
Why caution makes sense
Both can cause dryness and irritation, and benzoyl peroxide is described as the more drying of the two. Higher strengths and more product raise the chance of side effects. Stop a product that causes ongoing redness, itching or peeling.
A cautious way to proceed
Pick one as your main active, add the other only if a dermatologist suggests it, and patch-test first. Healthline suggests starting benzoyl peroxide at a lower strength. Follow each product's label. Cosmetic guidance, not medical advice.

These are consumer health sources, not trials of this pair or of your products. They agree that irritation is the main concern; they differ slightly on whether a dermatologist-planned combination is acceptable.
