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.
