AllerNote

AllerNote lets users evaluate cosmetic products against a personal list of allergens. By entering triggers identified from patch tests, personal experience, or a built‑in catalog of more than thirty common allergens, the tool creates an individual allergy profile. Users can then scan a product label with a camera, paste an ingredient list, or drag‑and‑drop a photo, and the system matches the ingredients to the profile, returning a verdict of Safe, Warning, or Avoid.

The service relies on clinical allergen databases such as ACDS and CARD and follows INCI naming conventions, mapping each allergen to all known chemical synonyms. This enables detection of hidden triggers—e.g., various fragrance compounds listed under different names—that generic scanners may miss. Results are presented in plain English, and the platform supports multiple languages and curved label images without requiring user registration.

AllerNote is aimed at individuals with contact dermatitis or other cosmetic sensitivities who need product‑specific guidance rather than overall safety scores. It offers free, on‑the‑fly analysis and includes tools like a product comparator, conflict checker for actives, and a patch‑test translator to aid decision‑making.
