Outcomes where both Adapalene and Clindamycin (topical) have evidence — compare verdict strength side-by-side.
Topical use. Adapalene 0.1% (OTC) or 0.3% (prescription) gel/cream is applied as a thin layer to the whole affected area once daily, usually at night, starting every other day and building to nightly as tolerated. Full benefit takes ~8-12 weeks. There is no oral or systemic dose — it is not ingested. It is most effective combined with benzoyl peroxide. This library does not provide an ingestion protocol.
evening
Adapalene 0.1% gel/cream (OTC), applied nightly to the whole area
Clindamycin phosphate 1% gel, lotion or solution applied to the affected area once or twice daily, depending on the product. It should be used WITH benzoyl peroxide or a topical retinoid rather than alone, and for a limited course rather than indefinitely. A prescription medicine and a clinician's decision.
