Sun exposure causes skin aging and dehydration, which can lead to the formation of pigment spots and wrinkles.
The Biologique Recherche Protection UV, SPF 50 is part of the three-step Biologique Recherche suncare protection concept:

Step one is to use Préparation UV up to four weeks before sun exposure to stimulate natural tanning and prevent pigmentation. Using Protection UV SPF 50 is step two and protects the skin against the harmful effects of UVAs, UVBs and infrared radiation and is photostable and water resistant. Finally, the Réparation UV is used after sun exposure to nourish the skin and prevent peeling and dullness.
