Outcomes where both Adapalene and Benzoyl Peroxide 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
Topical OTC use. Benzoyl peroxide is used at 2.5-10% in gels, creams, and washes, applied to acne-prone areas once or twice daily; lower strengths (2.5-5%) are usually as effective as 10% with less irritation. There is no oral or systemic dose — it is not ingested. It is often combined with a retinoid (e.g. adapalene) for greater effect. This library does not provide an ingestion protocol.
