Outcomes where both Benzoyl Peroxide and Tazarotene 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
Apply a thin layer once daily in the evening to clean, dry skin. Strengths: 0.045% lotion, 0.05% and 0.1% cream/gel, 0.1% foam. Start every other night if irritation appears.

Tazarotene 0.045% lotion
Stacking tazarotene with another retinoid or a strong acid compounds irritation on a drug whose irritation already drove 20/283 discontinuations over 12 months. Use one retinoid at a time.
