Procedure to assess neutralization potential of free radicals skin

摘要

Procedure to evaluate the antioxidant potential of the skin comprising the steps of: - removing non-invasively on the skin at least one neutralizer analyte of free radicals present in the surface thereof, using a porous support (6), for collect or analyte (s) of the skin surface, said porous support being impregnated with an extraction liquid (L), where the extraction comprises the solubilization or the analyte (s) with extraction liquid (L ), - then placing said porous support in contact with a different substrate (8) of the porous support, said substrate being loaded with a reagent (3) comprising DPPH, and - allowing the analyte thus extracted react in contact with the reagent ( 3) present on said substrate (8), said substrate being capable of producing an observable reaction in the presence of the analyte optically, characterized in that a color scale is used (13) hard nte visual detection of a color change of the reagent.
