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.

Leave-on topical gel, foam, or cream (OTC ~10%, or prescription 15-20%)

Topical use, typically ~2-5% tranexamic acid in a serum applied to areas of melasma once or twice daily, alongside daily sunscreen. There is no oral or systemic dose in this cosmetic context — the ingested medication is a separate prescription use with clotting-risk considerations. This library does not provide an ingestion protocol.
