Title (EN) HAIR REMOVAL USING OPTICAL PULSES
(FR) EPILATION A L'AIDE D'IMPULSIONS OPTIQUES
Abstract:
(EN) A method and apparatus for simultaneously effecting the removal of multiple hairs from a skin region by using light energy to destroy hair follicles in the region. Light energy is applied to the region through an applicator which converges the light energy to enhance destruction of desired portions of the follicles, is preferably pressed against the skin region to deform the upper layers of the skin reducing the distance from the skin surface to portions of hair follicles which are to be destroyed, including the bulge and papilla of the follicles, and which applicator is preferably cooled to minimize or eliminate thermal damage to the epidermis in the region being irradiated. Parameters for the irradiation, including pulse duration, are selected to effect complete damage of desired portions of the hair follicles in the region with minimal damage to surrounding tissue and to the patient's epidermis.
(FR) L'invention a pour objet un procédé et un appareil pour simultanément retirer de multiples poils d'une zone de peau à l'aide d'une énergie lumineuse et détruire les follicules pileux dans cette zone. L'énergie lumineuse est appliquée à ladite région à l'aide d'un applicateur qui fait converger l'énergie lumineuse pour améliorer la destruction des parties requises des follicules. L'applicateur est, de préférence, comprimé contre la zone de peau pour déformer les couches supérieures de la peau, en réduisant la distance entre la surface de la peau et les parties des follicules pileux à détruire, y compris le bulbe et les papilles des follicules. L'applicateur est, de préférence, refroidi pour minimiser ou supprimer toute détérioration thermique de l'épiderme dans la zone irradiée. Les paramètres d'irradiation, comprenant la durée des impulsions, sont sélectionnés pour assurer une détérioration totale des parties requises des follicules pileux dans la zone, en endommageant le moins possible les tissus environnants et l'épiderme du patient.
