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-Topikum als Gel, Schaum oder Creme (rezeptfrei ~10 % oder verschreibungspflichtig 15–20 %)

Topical OTC use. Leave-on and wash-off acne products contain 0.5-2% salicylic acid, applied to affected areas once or twice daily and built up as tolerated; professional peels (20-30%) are applied in-office. There is no oral or systemic dose in this context — it is not ingested (and large-area/high-concentration use can cause systemic salicylate absorption, so follow label limits). This library does not provide an ingestion protocol.
