Cheapest way into a real retinoid. The OTC 0.1% gel works; the 0.3% is prescription. Pairs well with benzoyl peroxide because it is chemically stable with it.

Access

OTC 0.1% gel is inexpensive and widely stocked; prescription 0.3% and combination gels cost more and are often generic.

0.1% gel (OTC drug)

Adapalene/benzoyl peroxide 0.1%/2.5% and 0.3%/2.5% (Rx)

How to use it

Thin layer once daily at night to the whole acne-prone area, not spot treatment. Results at 8–12 weeks; keep going to prevent new lesions.

Side effects and cautions

Dryness and mild peeling
Redness in the first weeks
Sun sensitivity

Get advice first if

AAD advises avoiding topical retinoids in pregnancy as a precaution even though adapalene absorption is low. Stop before waxing.

Regulatory status

0.1% gel is an FDA-approved OTC drug (switched in 2016); higher strengths and combinations are prescription. Prescription-only in most other countries.
