Abstract

L'invention concerne un appareil cosmétique (100). Il comporte un logement (1) et un module de source de lumière (10) agencé pour émettre de la lumière dans une première longueur d'onde prédéfinie via l'utilisation d'une ou de plusieurs sources de lumière (11), par exemple LED. Un module optique (20) est agencé pour fournir la lumière émise par le module de source de lumière (10) à une partie du corps d'un utilisateur pour obtenir un premier effet cosmétique. En tant qu'exemple, l'effet cosmétique ciblé peut être le bronzage (en utilisant la lumière dans la plage de 400 à 440 nm), le traitement de l'acné (400 à 440 nm), ou le traitement du psoriasis (300 à 360 nm). Le module optique comprend un dispositif de conversion de couleur réglable (30) agencé pour convertir la lumière de la première plage de longueur d'onde en lumière dans une seconde plage de longueur d'onde prédéfinie pour obtenir un second effet cosmétique, par exemple le rajeunissement cutané (580 à 660 nm).
