Abstract
A method of assessing oxidative stress in a mammal is provided. The method comprises: a) exposing skin cells of said mammal to an oxidizable moiety; b) exposing said skin cells to an external aggression; and c) assessing a reaction product of said oxidizable moiety; wherein prior to said assessing step (c), said skin cells are non-invasively removed from said mammal such that said removed skin cells are viable. A personal care composition comprises a sunscreen, wherein said composition has an oxidation protection factor of at least about 40%.
