Outcomes where both Benzoyl Peroxide and Hyaluronic Acid (topical) 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. HA serums are applied to clean, slightly damp skin once or twice daily and sealed with a moisturizer to hold water in (in very dry air, HA applied to dry skin can draw moisture outward). There is no oral, injectable, or systemic dose in this cosmetic context. This library does not provide an ingestion protocol.
