Outcomes where both Clindamycin (topical) and Mandelic Acid (topical) have evidence — compare verdict strength side-by-side.
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 cosmetic only. Leave-on mandelic acid is used at roughly 5-10% in serums; professional peels use higher strengths (often a salicylic-mandelic combination). Apply to clean skin, building frequency as tolerated, with daily sunscreen. There is no oral or systemic dose — it is not ingested. This library does not provide an ingestion protocol.
evening
Leave-on serum (≈5-10% mandelic acid) or a professional (salicylic-)mandelic peel
