Notes

• CORS is enabled — call it directly from the browser.
• result is null when an ingredient isn't in the database. match is "exact" for a direct alias hit or "partial" when we matched the trailing INCI name inside a longer token (e.g. "cocos nucifera coconut oil" → Coconut Oil).
• Limits: max 200 ingredients / 20,000 characters per request.
• Responses are cached at the edge; no API key required for normal use.
• Want the whole database instead of per-request lookups? Download it from the open dataset page (CSV/JSON, CC BY 4.0).
• Ratings are general guidance compiled from published references, not medical advice. Please attribute acnesafecheck.com.
