Summary

To evaluate the protective effect of three sunscreens on the pigmentation caused by visible light in comparison to an untreated control zone in healthy volunteers.

Detailed description

The sunscreens usually used as photoprotectors are known to protect in the UV domain (UVB and UVA). However, until recently visible light (400-700 nm) was considered as devoid of any photobiological effects on cutaneous tissue. Over the last two decades, with the development of photodynamic therapies and various dermatological treatments using visible laser light, several studies have reconsidered the cutaneous effect of visible light on the skin, in particular the induction of pigmentation. The aim of this study was to assess the ability of sunscreens with a protective efficacy in the UV domain to prevent the pigmentation induced by Visible Light.
