What is it?
The Repeat Insult Patch Test (RIPT), also known as Human Repeat Insult Patch Test (HRIPT), is the industry standard for determining allergy safety in skincare products. The RIPT is a sensitization test used by personal care brands to assess the likelihood of allergic reactions, irritation, and sensitization.
Why does it matter?
As new shave and skincare products pop up with innovative formulas, complex ingredients are being introduced and the risk of exposure to potential irritants increases. Even the classic shave foams you’ve seen your whole life are littered with harmful ingredients. Brands claiming to be hypoallergenic, dermatologist approved, or non-irritating must substantiate those claims by proving their ingredients are safe for use on the skin.
Savvy consumers should absolutely look for assurances from any personal care or skincare brand that their products are actually clean. While brands will provide evidence of passing a recognized safety test (RIPT/HRIPT), it is also a good habit to check the ingredients on the bottle. Here are the most common “bad actors” we see in big brands that cause skin irritation:
- Sodium Lauryl Sulfate, also known as SLS
- Butane/isobutane (i.e. aerosols)
