Abstract

L’invention concerne une méthode de sélection d’une composition écobiologique permettant de lutter contre la pigmentation et l’hyperpigmentation induites par la lumière visible et la sélection d’ingrédients et de compositions ainsi évalués. Cette méthode comprend le calcul d’un taux de protection BLP utilisant la mesure de la couleur de la peau par une mesure de l’ITA ou la mesure de l’absorbance de la composition entre deux longueurs d’onde. L’invention utilise une méthode simple et peu coûteuse utilisable à l’échelle industrielle permet d’évaluer un principe actif ou une composition et de sélectionner ceux et celles qui permettent une protection efficace avec un BLP d’au moins 50 %, noté BLP 50 ou BLP 50+.The invention relates to a method for selecting an ecobiological composition for combating pigmentation and hyperpigmentation induced by visible light and the selection of ingredients and compositions thus evaluated. This method comprises calculating a BLP protection rate using the measurement of skin color by measuring the ITA or measuring the absorbance of the composition between two wavelengths. The invention uses a simple and inexpensive method that can be used on an industrial scale to evaluate an active ingredient or a composition and to select those that provide effective protection with a BLP of at least 50%, noted BLP 50 or BLP 50+.
