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.
