Abstract

Se describe un método para la determinación del factor de protección solar (FPS) in vitro cuyo fin es lograr reproducibilidad y exactitud en las determinaciones y reemplazar el uso de pruebas sobre seres vivos. Para ello se hace uso del ácido hialurónico, un sustrato natural presente en la piel humana, el cual se prueba en solución o como película sólida, en concentraciones inferiores al 1% p/v y usando de un espectrofolimetro. Una vez calibrado se ha utilizado para corroborar el factor de protección ofrecido por bloqueadores solares comerciales.
