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.

Leave-on-Gel/-Creme (2,5-5 %) oder eine feste Kombination mit einem Retinoid

Topical cosmetic only. OTC retinol is formulated roughly 0.1-1% in leave-on serums or creams and applied to clean, dry facial skin at night, starting 2-3 nights per week and building to nightly as tolerated. There is no oral, injectable, or systemic dose — this is not ingested. Higher concentrations work somewhat better but irritate more; pair with a moisturizer and a morning sunscreen. This library does not provide an ingestion protocol.
