A salicylic acid cleanser is a good fit if your main problem is blackheads, whiteheads and oily skin, and a weaker choice if you mostly get red, inflamed pimples. Pick a 2% wash for oily, blackhead-prone skin, or a 0.5% wash if your skin is sensitive or you already use other acne treatments. Use it once a day to start, and pair it with benzoyl peroxide or a retinoid if you also get inflamed spots.
Salicylic acid is a beta hydroxy acid (BHA). It’s oil-soluble and loosens the connections between dead skin cells, which helps clear the plugs that form blackheads and whiteheads (comedones). It’s one of the few ingredients allowed as an over-the-counter acne drug under the FDA’s acne monograph (M006), at strengths from 0.5% to 2%.
We don’t test products hands-on. The cleansers below were chosen using the criteria explained further down and the manufacturers’ published details.
What the evidence says
Salicylic acid is popular, but it has a thinner evidence base than the two most-recommended acne treatments (our salicylic acid guide covers the ingredient in depth):
- The American Academy of Dermatology’s 2024 acne guideline gives salicylic acid a conditional recommendation, with evidence rated as low certainty. By comparison, benzoyl peroxide and topical retinoids get strong recommendations.
- A 2020 Cochrane review of salicylic acid, azelaic acid and other non-antibiotic topicals found the evidence for many of these treatments limited, with few high-quality trials.
- In a small 1989 crossover study of 30 people, a 2% salicylic acid cleanser significantly reduced comedones, while a 10% benzoyl peroxide wash did not over the same period. It’s an old, small study, but it fits the idea that salicylic acid is most useful for clogged pores.
Who a salicylic acid cleanser suits
Good fit:
- Oily skin with visible blackheads, especially on the nose and chin
- Small whiteheads and rough, bumpy texture
- People who find benzoyl peroxide too drying or dislike its bleaching
- A maintenance wash once acne is under control
Not enough on its own:
- Frequent red, inflamed pimples
- Deep, painful lumps or cysts (see a dermatologist)
- Acne that’s leaving scars or dark marks

Salicylic acid vs benzoyl peroxide cleanser: which one?
Both are OTC acne drugs, and both come as washes. They do different jobs:
| Feature | Salicylic acid cleanser | Benzoyl peroxide cleanser |
|---|---|---|
| OTC strength (FDA M006) | 0.5%–2% | 2.5%–10% |
| Main job | Loosens dead skin in clogged pores | Kills acne bacteria; reduces inflamed pimples |
| Best for | Blackheads, whiteheads, oily skin | Red, inflamed pimples |
| 2024 AAD guideline | Conditional recommendation | Strong recommendation |
| Bleaches fabric? | No | Yes |
| Stable with adapalene? | Can be used in the same routine; watch for dryness | Yes, adapalene is chemically stable with it |
If your acne is mostly clogged pores, start with salicylic acid. If it’s mostly red pimples, start with benzoyl peroxide. If it’s both, which is common, you can use one in the morning and the other at night, or use benzoyl peroxide and add a retinoid such as adapalene, which also targets clogged pores and has stronger evidence than salicylic acid.
Sample routines using a salicylic acid cleanser
Mostly blackheads and oily skin:
- Morning: gentle cleanser or water rinse, oil-free moisturizer, sunscreen
- Night: salicylic acid cleanser, moisturizer
Blackheads plus some inflamed pimples:
- Morning: benzoyl peroxide wash, moisturizer, sunscreen
- Night: salicylic acid cleanser, moisturizer (add adapalene later if needed, and switch the night wash to a plain cleanser if your skin gets irritated)
Using a retinoid already:
- Morning: 0.5% salicylic acid cleanser (or a plain cleanser on sensitive days), moisturizer, sunscreen
- Night: gentle cleanser, retinoid, moisturizer
Give any routine about 8 to 12 weeks before judging it, and change one thing at a time.

How to use a salicylic acid cleanser
- Start once a day, usually in the evening, for the first two weeks.
- Wet your skin with lukewarm water and massage a small amount in with your fingertips for about 30 to 60 seconds. There’s no need to scrub. The AAD warns that scrubbing can make acne worse.
- Rinse well and pat dry.
- Moisturize with a fragrance-free product. See our moisturizer guide for acne-prone skin.
- Increase to twice a day only if your skin tolerates it. In a small randomized trial, washing twice a day with a mild cleanser improved blackheads and whiteheads, while washing more often than that didn’t add benefit.
Using it with other acne treatments
The OTC label warns that skin irritation and dryness are more likely if you use another topical acne medication at the same time. That doesn’t mean you can’t combine them; it means you should add one at a time and watch your skin.
- With benzoyl peroxide: benzoyl peroxide wash in the morning, salicylic acid cleanser at night. Or alternate days at first.
- With adapalene or tretinoin: use the salicylic acid cleanser in the morning and the retinoid at night. If your skin gets raw, switch the morning wash to a plain gentle cleanser. Our Differin vs tretinoin guide covers retinoid routines.
- With leave-on acids: avoid stacking a salicylic acid cleanser with leave-on glycolic or salicylic acid toners and serums while you’re starting a retinoid.

Side effects and safety
- Dryness, peeling and stinging are the usual side effects. Cut back to once a day or every other day.
- Rare allergic reactions. In 2014 the FDA warned that OTC acne products with salicylic acid or benzoyl peroxide can rarely cause serious allergic reactions. Get emergency help for throat tightness, trouble breathing, feeling faint, or swelling of the face, eyes, lips or tongue.
- Pregnancy. Check with your obstetrician or dermatologist before using salicylic acid products while pregnant or breastfeeding.
- Aspirin allergy. Salicylic acid is a salicylate, the same chemical family as aspirin. If you’ve had a reaction to aspirin, ask a pharmacist or doctor before using it.
When to see a dermatologist
See a clinician if your acne hasn’t improved after about 3 months of consistent OTC treatment, if you have deep, painful lumps, or if acne is leaving scars or dark marks.
