Photo patch test

The photo patch test assesses the skin's reaction to a product under exposure to UV light.

Carried out under dermatological control on volunteers, it allows the detection of potential photosensitization of an ingredient or a finished product.

This is an essential safety test for sun cosmetics or care products exposed to light.
