This tool checks against a curated reference list of ~90 commonly discussed skincare ingredients, built from general cosmetic-chemistry consensus. It is a starting point, not a lab test, a medical opinion, or a guarantee — an ingredient marked "verified" isn't guaranteed to suit your specific skin, and one marked "flagged" doesn't mean it's unsafe for everyone. Reactions are individual. For a deeper, more exhaustive check, see
INCI Decoder or the EU's
CosIng database. If you have known allergies or a diagnosed skin condition, check with a dermatologist directly.
