Summary

The study intends to get knowledge on pigmentation induced by visible light on Asian/Chinese skin type and darker skin type, and to evaluate and to compare with a non-treated control zone and between them, the efficacy of photoprotective effect of different products after visible light exposure, between \[400-700nm\], on these skin types compared to Caucasian for whom the investigators already got knowledge.

Detailed description

The main objective of this study is: \- To assess the ability of protective agents to prevent the pigmentation under visible light exposures (VL) in healthy volunteers with different skin type (caucasian, asian and darker skin) by skin colorimetry (Delta E) and clinical evaluation. The secondary objectives are: * To assess the local tolerance and safety of the products under VL exposure by recording adverse events and safety * To assess the safety of the different Investigational Products.
