Cosmetics listed on Amazon need to submit/RIPT patch test report.

Cosmetics are in direct contact with the surface of the human body when used. If there is a problem with the product, it may cause adverse skin reactions. As a commonly used cosmetic safety test, the patch test can detect this potential possibility to ensure the safe use of cosmetics. Common types of skin patch tests include closed patch test, repeated open test, and repeated injury patch test. In general, skin occlusion patch testing is widely used in cosmetics. In special cases, such as freckle cosmetics and powdered (such as powder, foundation) sunscreen cosmetics, when the human skin patch test shows irritating results or it is difficult to judge the results, repeated open skin smear tests should be added. The skin repeat open test is also applicable to products such as shower products, hair dyes, and hair removal.
