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.
Any time of day
Leave-on or wash-off acne product (0.5-2% salicylic acid)
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. Use fresh, properly stored product (oxidised oil may raise allergy risk). A small-area test first can show irritation but does not rule out an allergy. 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.
