What does "hypoallergenic" mean on a skincare product label?

It means nothing! The word “hypoallergenic” is a marketing term that manufacturers use to imply that a product is less likely to cause an allergic reaction. Consumers are led to believe that these products contain few or no irritating ingredients, thus producing fewer allergic reactions. In actuality, there are no federal standards, guidelines or definitions that govern the use of the term "hypoallergenic." Manufacturers are not required to submit substantiation of their hypoallergenic claims to the FDA.
