"Hypoallergenic" sounds like a guarantee that a product won't cause a reaction. On cosmetics in the US, it isn't. Here's what the word means, what it doesn't, and what to look at instead.
There's no official definition
The FDA has no federal standard or definition for "hypoallergenic" on cosmetics. A brand can use the word based on its own testing, or simply its own judgment. It suggests the product is less likely to cause a reaction, but it doesn't promise anything, and it doesn't tell you how it was tested.

How to patch test
Apply a small amount to the same small area, such as the side of the neck or behind the ear, once or twice a day for several days. If there's no redness, itching or bumps, try it on a small area of your face. Full steps in how to patch test skincare.
FAQ
Does hypoallergenic mean I can't be allergic to it?
No. Anyone can react to almost any ingredient. "Hypoallergenic" only suggests a lower likelihood.
Is hypoallergenic the same as fragrance-free?
No. A product can be called hypoallergenic and still contain fragrance. Check the ingredient list.
Who decides if a product is hypoallergenic?
In the US, the brand does. There's no required test or approval for the word on cosmetics.
What should I do if a product irritates my skin?
Stop using it, rinse with lukewarm water, and keep the routine simple until skin settles. If the reaction is severe or doesn't improve, see a healthcare provider.
