A new way for skin oxidation investigation. Starting with strips which were UV irradiated,  LC-MS/MS allowed to investigate the main methionine oxidation sites which were then targeted by MRM methods (1). This approach shows the interest of the method for studying oxidation in a targeted or untargeted way for cosmetics, after skin stripping .

Of course, it may be used to study other modifications like post-translational modifications (2).

With MS-Phylogene, you can also characterize the oxidation and understand the effects of your anti-oxidant product.
