Methods and apparatus for damaging hair follicles using a series of rapidly-delivered low-fluence pulses of coherent or incoherent light are disclosed herein. In some embodiments, the pulses of coherent or incoherent light have a wavelength or wavelengths primarily in the range between 750 nm and 1500 nm. In some embodiments, applied electromagnetic radiation comprising the rapidly-delivered low-fluence pulses is effective for concomitantly heating both the sub-dermal layer (i.e. the dermis) of the tissue and the hair follicles. In some embodiments, the thermal damaging of the hair follicles is useful for facilitating hair-removal.
Cette invention concerne des procédés et un appareil visant à endommager les follicules pileux au moyen d'une série d'impulsions de lumière cohérente ou incohérente à faible fluence administrées rapidement. Dans certains modes de réalisation, les impulsions de lumière cohérente ou incohérente présentent une ou plusieurs longueurs d'onde comprises principalement entre 750 nm et 1500 nm. Dans certains modes de réalisation, l'application d'un rayonnement électromagnétique comprenant les impulsions à faible fluence administrées rapidement permet de faire chauffer simultanément à la fois la couche sous-cutanée (autrement dit le derme) des tissus et les follicules pileux. Dans certains modes de réalisation, la destruction thermique des follicules pileux sert à faciliter l'épilation.
