Topical cosmetic only. Bakuchiol is typically formulated around 0.5-1% in leave-on serums or creams and applied to clean skin once or twice daily. Unlike retinol it is not photolabile, so it can be used AM or PM, though daily sunscreen is still recommended. There is no oral, injectable, or systemic dose — it is not ingested. This library does not provide an ingestion protocol.

Any time

Leave-on topical serum or cream (0.5-1% purified bakuchiol)

Topical OTC. Apply a broad-spectrum SPF 30+ sunscreen daily to sun-exposed skin as the last step of a morning routine, using an adequate amount (about 2 mg/cm² — roughly a nickel-sized dollop for the face, a shot-glass for the body) and reapply every ~2 hours of sun exposure and after swimming/sweating. Mineral (zinc oxide / titanium dioxide) filters are preferred if you're concerned about systemic absorption. There is no oral or systemic dose — it is not ingested. This library does not provide an ingestion protocol.
