Abstract
An in vitro method for the prediction of in vivo UVA protection by a composition with sunscreen properties. The method includes the steps of: determining in vivo SPF; determining in vitro SPF based on the sunscreen's absorbance spectrum in the UV region; normalizing the absorbence spectrum based on integration area of UVA1; and calculating the PFA-PPD in vitro.
