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.
morning
Fixed-dose clindamycin 1% with benzoyl peroxide
Topical OTC use. Leave-on and wash-off acne products contain 0.5-2% salicylic acid, applied to affected areas once or twice daily and built up as tolerated; professional peels (20-30%) are applied in-office. There is no oral or systemic dose in this context — it is not ingested (and large-area/high-concentration use can cause systemic salicylate absorption, so follow label limits). This library does not provide an ingestion protocol.
