Efficacy Evaluation of Products Against Long Wavelength Ultraviolet A1 and Visible Light Induced Biological Effects

Efficacy Evaluation of Products Against Long Wavelength Ultraviolet A1 and Visible Light Induced Biological Effects

The purpose of this study is to evaluate the efficacy of topical products in providing protection against the visible light and ultraviolet A1 (UVA1) part of sunlight. Ultraviolet radiation and visible light are both components of sunlight that reach the earth. It is important to test these topical products against visible light and UVA1 because our current sunscreens may not protect against these very well.
