Abstract

Un dispositif pour soins de la peau selon un mode de réalisation comprend une source de lumière (DEL (41)), un diffuseur (20) capable de transmettre la lumière (L) émise par la source de lumière et d'irradier la lumière depuis le côté pointe de celui-ci, et une partie base (11) à laquelle le diffuseur (20) est disposé. Le diffuseur (20) est pourvu d'une partie de guidage de lumière (21) pour guider la lumière (L) émise par la source de lumière vers le côté de pointe de celui-ci, et d'une partie d'irradiation (22) disposée au niveau de la pointe de la partie de guidage de lumière (21) et irradiant l'extérieur avec de la lumière (L). La partie d'irradiation (22) est pourvue d'une surface inclinée (222), dont une extrémité (222a) est reliée à une surface latérale (211) de la partie de guidage de lumière (21), la surface inclinée (222) s'inclinant vers l'intérieur vers un autre côté d'extrémité (222b) de celle-ci. La partie d'irradiation (22) est pourvue d'une surface de pointe (221) reliée à l'autre extrémité (222b) de la surface inclinée (222) et ayant une surface ou une forme plate faisant saillie de manière distale vers l'extérieur.
