Abstract

Procedimiento para evaluar el potencial antioxidante de la piel, que comprende los pasos consistentes en: - retirar de manera no invasiva sobre la piel al menos un analito neutralizador de radicales libres presente en la superficie de ésta, utilizando un soporte poroso (6), para recoger el o los analito(s) de la superficie de la piel, dicho soporte poroso estando impregnado con un líquido de extracción (L), donde la extracción comprende la solubilización del o de los analito(s) con el líquido de extracción (L), - después, poner dicho soporte poroso en contacto con un substrato (8) diferente del soporte poroso, dicho substrato estando cargado de un reactivo (3) que comprende DPPH, y - permitir al analito así extraído reaccionar en contacto con el reactivo (3) presente sobre dicho substrato (8), dicho substrato siendo capaz de producir una reacción observable ópticamente en presencia del analito, caracterizado por el hecho de que se utiliza una escala colorimétrica (13) durante la detección visual de un cambio de color del reactivo.
