"Hypo" means under or less than, so it’s a product that’s less likely to trigger an allergic reaction.

Many things we use every day, like cleansers, soaps, deodorants, makeup, and even mouthwash, have ingredients that can trigger a skin allergy. When you expose your skin to these ingredients, most often fragrances and chemicals used as preservatives, you can get contact dermatitis. It starts as red areas that itch and swell. Some people get rashes or blisters.

If you see "hypoallergenic" on the label, it means the product doesn’t have those things in it. But manufacturers don’t have to prove that claim. There are no regulations or standards for them to follow.

Using hypoallergenic products makes a reaction less likely, but nothing can guarantee it will never irritate your skin or trigger an allergy. Test anything new before you use it, especially if you have had skin reactions before. Dab a little on your inner wrist or elbow and wait. You should know how it affects you within 24 hours.
