A prescription-strength retinoid available over the counter. The single most effective acne product you can buy without seeing a doctor.

At a Glance

Recommended

Retinoids speed up skin cell turnover, which pushes existing clogs to the surface faster. That can make acne look worse for the first several weeks — often 4 to 12 — before it improves. Many people quit right at this point, which is the wrong moment.

Adapalene is a retinoid built for acne. Unlike products that clean up after clogs form, it helps stop pores from clogging in the first place, so it works on blackheads and whiteheads as well as pimples.

It is also more stable and less irritating than tretinoin, which makes it a sensible retinoid to start with. Give it at least 12 weeks before judging results.

How it works

This is the most useful thing on a drugstore shelf — a prescription-strength retinoid you can buy for about $15 without seeing a doctor.

Retinoids are the only OTC ingredient that treats acne at the source: they stop pores from clogging in the first place, rather than cleaning up after they have. That means they clear blackheads and whiteheads as well as inflamed pimples — something benzoyl peroxide and salicylic acid don't do nearly as well.

Adapalene is also more stable and less irritating than tretinoin, which is why it's the sensible retinoid to start with.

And it's a bonus anti-aging product. The same cell turnover and collagen stimulation that clears acne also softens fine lines — two treatments in one tube.

Everyday habits

How to use it

When: Start 2 to 3 nights a week, always at night.How much: Use a pea-sized amount for the whole face. Steps: Apply to clean, dry skin. To reduce irritation, you can buffer by applying moisturizer first, then the product, then more moisturizer. Sunscreen: Wear sunscreen every morning. Retinoids make skin more sensitive to the sun. What to expect: Skin often gets worse before it gets better. A purge of 4 to 12 weeks is common as clogs surface, and early dryness and flaking are normal. Build up slowly. Careful: Avoid the immediate eye area. Do not layer it with other strong actives at first.

Who should be careful+

The purge is real. Skin usually gets worse for 4–12 weeks before it gets better — retinoids push existing clogs to the surface. Most people quit right here, which is exactly the wrong moment. Push through.

Start slowly. Twice a week, a pea-sized amount for the whole face, at night. Build up over months. Going daily from day one is how people conclude they "can't tolerate retinoids."

Expect dryness and flaking early on. Buffer it: moisturizer first, then Differin, then moisturizer again.

Wear sunscreen. Retinoids make skin more sun-sensitive.

Be patient. Give it 12 weeks minimum before judging.

Guidelines of care for the management of acne vulgaris (https://doi.org/10.1016/j.jaad.2023.12.017) — American Academy of Dermatology evidence-based guideline (2024, systematic review) strongly recommends topical retinoids such as adapalene as a core acne therapy, backing the claim that retinoids are a mainstay acne treatment. 2. Mechanisms of the comedolytic and anti-inflammatory properties of topical retinoids (https://pubmed.ncbi.nlm.nih.gov/15696984/) — Explains that topical retinoids (including adapalene, a receptor-selective third-generation retinoid) act on the microcomedo with comedolytic and anti-inflammatory effects, supporting the mechanism that retinoids stop pores from clogging at the source. 3.
