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.

Topical cosmetic only. Niacinamide is typically formulated at 2-5% in leave-on serums, creams, or gels and applied to clean skin once or twice daily (AM and/or PM). It layers well under sunscreen and with most other actives. There is no oral, injectable, or systemic dose in this cosmetic context — it is not ingested here. This library does not provide an ingestion protocol.
