Outcomes where both Benzoyl Peroxide and Panthenol (provitamin B5) have evidence — compare verdict strength side-by-side.
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.
any
Leave-on gel/cream (2.5-5%) or a fixed combination with a retinoid
Topical cosmetic only. Panthenol/dexpanthenol is used at roughly 1-5% in moisturizers, soothing creams, and after-procedure ointments, applied to the skin as directed. There is no oral, injectable, or systemic dose in this context — oral vitamin B5 is separate. This library does not provide an ingestion protocol.
