Outcomes where both Ceramides (topical) and Hydroquinone have evidence — compare verdict strength side-by-side.
Topical cosmetic only. Ceramide-containing moisturizers are applied liberally to clean skin once or twice daily (and after bathing, to damp skin, to lock in water). There is no oral, injectable, or systemic dose in this context — it is not ingested. This library does not provide an ingestion protocol.
any
Ceramide-containing cream or lotion (with cholesterol and fatty acids)
Prescription topical. Hydroquinone is used at 2-4% (often as the triple-combination with a retinoid and a mild corticosteroid), applied to pigmented areas usually at night, in time-limited courses (commonly with treatment breaks) under clinician supervision, always with daily sunscreen. There is no oral or systemic use. Avoid indefinite continuous use because of ochronosis risk. This library does not provide an ingestion protocol.
