Brief Summary

Main objective is to show that a photoprotective sunscreen having a protection against the visible light is more effective than a sunscreen having the same UVA AND UVB protection but with a low (weak) protection against the visible, to prevent the relapses of the melasma during the summertime.

Detailed Description

40 melasma affected women will be included and randomized in two parallel groups (one group protected by a UVA+UVB+visible extended sunscreen and one group group protected by a UVA+UVB sunscreen).

There will be 3 visits: Baseline, T2.5months and T5months (final visit).

Products application frequency: twice daily(morning and afternoon) and additional applications every 2 hours in case of solar exposure.

Main evaluation criterion: the MASI score assessed from standardized photographs (system VISIA, Canfield Scientific, USA) at Baseline, middle and end of study.
