UVA Protection Factors of SPF 50 and 50+ Face Sunscreens

Brazil, France, Poland412 participantsStarted 2018-04-20

Plain-language summary

The goal of this observational study is to use the International Organization for Standardization (ISO) 24442:2011 in vivo method for assessment of the Ultraviolet A Protection Factor (UVAPF) of topical sunscreen products in healthy adults. The main question it aims to answer is to determine the degree of UVA-protection against UVA radiation. An area of each subject's skin is exposed to UVA light without any protection and another (different) area is exposed after application of the sunscreen product under test. One further area is exposed after application of a reference UVA sunscreen formulation (S2), which is used to validate the procedure.
