Experimental methods and arrangements for in vitro evaluation of sun protection factor

摘要

apparatus, methods and experimental arrangements for in vitro evaluation of sun protection factor the present invention describes an apparatus (100 comprising a UV-dosimeter (3) and an artificial skin (2), where the UV-dosimeter (3) changes its color due to exposure to uv rays and artificial skin (2) receives the application of a photo-protective formulation film in order to allow the formation of a protective layer similar to that formed on human skin, the dosimeter can also be a uv-dosimeter matrix The present invention also describes experimental arrangements encompassing said apparatus (100) together with a visual method analogous to conventional in vivo methods and another instrument based on photobleaching kinetics for in vitro evaluation of the sun protection factor.
