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 cosmetic only. Acne trials used a 5% tea tree oil gel applied to affected areas (typically twice daily). Avoid undiluted (100%) application, which is more irritating and sensitizing. Patch-test first, and use fresh, properly stored product (oxidized oil raises allergy risk). There is no oral or systemic dose — it is not ingested (and tea tree oil is toxic if swallowed). This library does not provide an ingestion protocol.
