Photoprotection Efficacy With Sunscreen Formulas Containing the Cyclic Merocyanine Long-UVA Absorber MCE, Under Real Sun Exposure

Study Overview
=================
Brief Summary
-----------------
To evaluate the photo-protector effect of BC_3 (E212657) formulated in SPF30 compared to SPF30 alone on real sun exposure induced pigmentation in healthy volunteers

Detailed Description
-----------------
The study intends to evaluate the clinical efficacy of the photo-protective cosmetic products (758637 10 and 758637 15) and to compare the photo-protection potential of the two products, after its application for 7 days on healthy female volunteers under the normal conditions of use planned by the sponsor. The study will also evaluate the tolerance of the two products on the skin of healthy female volunteers. The photo-protection is generally concerned with the reduction of exposure to ultra violet radiations, specifically UV-B and UV-A, primarily from the sun. The harmful radiations from the sun can cause various skin issues which can be as minor as skin tanning and as major as skin cancer. The photo-protective products can help in protection of the skin from the harmful sun radiation either by blocking them or absorbing them and preventing the rays to damage the skin The formula number of both the products are 758637 10 and 758637 15. The SPF value of both the product is 30.
