Where the data comes from
Allergen names, related ingredients and evidence levels were written by a board-certified allergist from the published literature. Product ingredients come from Open Beauty Facts, retailer product listings and FDA drug labels (DailyMed). Every product shows when its ingredients were last updated.
How we choose products
Products are shown or hidden only by whether their listed ingredients contain your allergens, and ordered only by US availability, how recently their ingredients were checked, and alphabetical order. We never accept payment to include, hide or rank products. Some store links may earn us a commission; they appear the same way on every product.
