The prefix “hypo” means “low”; this means hypo-allergenic products have low allergenic potential. This is verified by a repeat insult patch test, commonly called RIPT, in which human subjects are repeatedly exposed to our products and monitored to ensure that there is no irritation. These results are then reviewed and approved by a dermatologist. It’s important to keep in mind that our hypoallergenic products are unlikely to cause an allergic reaction, but since everyone is different, it’s possible for some individuals to have a reaction.
