    AnswerYes, but split them: benzoyl peroxide in the morning, salicylic acid at night.

    Both are over-the-counter acne drugs covered by the same FDA rule, so their labels share the same warnings. That rule also limits what a single wash with both can be.

    VerdictIrritation more likelySpace out
    WhyBoth are FDA-approved over-the-counter acne ingredients. Their required label warns that dryness and irritation are more likely if you use another acne medicine at the same time, and says to use one if irritation occurs.

    Both at onceYou may get more dryness or irritation. If that happens, the label says use only one acne medicine at a time.

    What each one does

    Salicylic acid · BHA

    What salicylic acid does

    A beta hydroxy acid (BHA) sold over the counter for acne. It can dry skin, so labels say to start once a day.

    Usual over-the-counter strength: 0.5–2%

    Benzoyl peroxide

    What benzoyl peroxide does

    An acne ingredient that works by oxidizing. It dries skin and can bleach hair, towels and pillowcases.

    Usual over-the-counter strength: 2.5–10%

    A face wash with salicylic acid and benzoyl peroxide?

    The FDA’s over-the-counter acne rule lists which acne actives may be combined in one product. It allows only two combinations, both of sulfur with a form of resorcinol. Benzoyl peroxide with salicylic acid is not on the list.

    So if a wash or cream seems to offer both, read the Drug Facts box:

    • The Active ingredient line shows which one the product treats as the acne drug, and at what percent. The allowed ranges are 2.5 to 10% for benzoyl peroxide and 0.5 to 2% for salicylic acid.
    • Active ingredients are always listed first, before the other ingredients.

    A wash stays on skin only briefly; see the body-wash tips below for how long the AAD suggests leaving one on.

    Body wash for back and chest acne

    For back and chest acne, the AAD’s routine is built around a benzoyl peroxide wash:

    • Use a foaming benzoyl peroxide wash every day and leave it on for two to five minutes. That helps it work on the thicker skin of the back; rinsing keeps it from bleaching sheets and towels.
    • 5.3% is less likely to dry or peel skin; 10% is the strongest you can buy without a prescription.
    • No loofahs, back brushes or hard scrubbing, and shower or change soon after sweating.
    • Expect results in six to eight weeks and clearing in three to four months. If nothing has changed after six to eight weeks, see a dermatologist.

    If you also use a salicylic acid body product, give it its own slot, morning or evening, apart from the benzoyl peroxide, as you would on the face.

    Which one to start with

    The plan above starts with benzoyl peroxide alone and adds salicylic acid in week 3. What each brings, so you can judge whether you need both:

    • Benzoyl peroxide lowers acne bacteria and, per the AAD, does most when paired with a treatment aimed at acne’s other causes. Mayo Clinic suggests starting with a 2.5% water-based product: lower strengths work as well as higher ones, with less risk of side effects.
    • Salicylic acid unblocks pores and exfoliates; Mayo Clinic notes it is sold at 0.5 to 2% as both leave-on and wash-off products.

    Give the plan time. The AAD’s yardstick is six to eight weeks or more before breakouts drop, and extra product won’t hurry it. Not sure which kind of pimple you have? Try the pimple type identifier.

    Questions people ask

    Can I add adapalene as a third product?

    Adapalene goes well with benzoyl peroxide: the AAD’s back-acne routine uses the two together. A third acne medicine adds irritation, though. The adapalene label links extra irritation to using several acne medications at once, and suggests holding off on it until any irritation from your current products has settled.

    SourcesAmerican Academy of Dermatology: Back acne: How to see clearer skinFDA label (DailyMed): adapalene gel 0.1%, OTC Drug Facts and leaflet (Dec. 2022)

    Does an acne face wash count as a second acne medicine?

    Yes, if its Drug Facts box lists salicylic acid or benzoyl peroxide as the active ingredient. The FDA acne rule covers washes and masks as well as leave-on products, and the warning about pairing it with another topical acne product is a required part of these labels.

    SourceFDA rule: 21 CFR 333.310, 333.320 and 333.350 (OTC acne drugs)

    What if my skin gets dry and flaky?

    With leave-on products, the FDA labeling rule tells you to drop to a single daily application, or every other day, once dryness or peeling gets annoying. Severe irritation is a reason to stop benzoyl peroxide and check with a doctor, per its label.

    SourceFDA rule: 21 CFR 333.310, 333.320 and 333.350 (OTC acne drugs)

    Who shouldn’t use benzoyl peroxide?

    Its required label says not to use it if you have very sensitive skin or are sensitive to benzoyl peroxide. It should also stay clear of the eyes, lips and mouth, and away from hair and dyed fabrics, which it can bleach.
