Safety-in-use test of facial cosmetic products on normal and self-assessed sensitive skin subjects.

As a suitable tool for assessing and establishing the skin and eye compatibility of facial cosmetic products, SIU studies can be designed according to specific consumer groups, skin types and product usage scenarios to better predict realistic in-use conditions. It can demonstrate the safe use of the investigated products for people of different ethnicities, skin types and with normal or self-assessed sensitive skin, single product use or regimen use. The test results are consistent with the inherently low irritation potential of the products.
