1. Patch test under a dermatologist’s medical control:

The product is being applied on patches that then sit on 12 individuals’ skin during 48 hours. If no allergic or irritation reaction of the skin is seen: then the test is passed!

2. Fysi sensitive skin patch test under medical control:

At fysi, we pushed this test further by running the same test on individuals with extra-sensitive skin. The doctor observed that even people with extra-sensitive skins tolerated the fysi products with no issue at all.
