Because there are no Federal standards or definitions that govern the use of the term "hypoallergenic", the term means whatever a particular company wants it to mean. Manufacturers of cosmetics labeled as hypoallergenic are not required to submit substantiation of their hypoallergenicity claims to FDA. So this really is not a useful description, and no product can be guaranteed to not cause an allergic reaction.
Each product on our website includes an ingredient list, as well as badges to show if they are acne safe, cruelty free, dye free, paraben free, sulfate free, etc. It is best to be aware of what ingredients are of personal sensitivity to you vs looking for a product claiming to be hypoallergenic, as there is no guarantee.
