Topical cosmetic only. Alpha-arbutin is typically used at roughly 1-2% in leave-on serums, applied to areas of hyperpigmentation once or twice daily, usually alongside daily sunscreen and often with other brighteners. There is no oral, injectable, or systemic dose — it is not ingested. This library does not provide an ingestion protocol.

Topical only. OTC cosmetic azelaic acid is typically around 10%; prescription strengths are 15% gel/foam (rosacea) and 20% cream (acne), applied as a thin layer to clean skin once or twice daily. There is no oral, injectable, or systemic dose. For rosacea or persistent acne, the prescription form under a clinician is the evidence-based route. This library does not provide an ingestion protocol.
