Photo patch test

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

Performed under dermatological control on volunteers, it allows the detection of potential photosensitivity of an ingredient or finished product.

This is an essential safety test in sunscreen cosmetics or skincare products exposed to light.
