Abstract

L'invention concerne une méthode d'épilation cutanée permanente ainsi qu'un appareil pour mettre en oeuvre celle-ci. Cette méthode qui consiste à insérer un filament conducteur dans le follicule de chaque poil à éliminer et à appliquer à l'aide de ce filament, un courant galvanique d'intensité donnée, un courant HF
d'intensité donnée ou une combinaison de ces deux courants au follicule du poil pour détruire la racine de ce dernier par l'électrolyse, thermolyse ou les deux, est caractérisée en ce que l'intensité d'au moins un des courants appliqués au follicule est modulée durant la durée de l'application lors d'une même insertion pour ainsi permettre une épilation permanente tout en réduisant la douleur perçue par le patient. Avantageusement, la modulation en intensité du courant est effectuée en discontinu, selon une suite de séquences de durée variant d'une fraction de seconde à plusieurs secondes, le courant appliqué durant chaque séquence successive étant d'intensité constante, cette intensité étant elle-même identique aux intensités des séquences précédentes ou différentes de celles-ci.
Selon un mode particulier de réalisation, la durée des séquences et l'intensité de chaque courant appliqué durant chaque séquence sont préprogrammés. The invention relates to a skin hair removal method.
permanent as well as an apparatus for implementing it. This method of inserting a conductive filament into the follicle of each hair to be removed and applied using this filament, a galvanic current of given intensity, a HF current of given intensity or a combination of these two currents at hair follicle to destroy the root of the hair by electrolysis, thermolysis or both, is characterized in that the intensity of at least one of the currents applied to the follicle is modulated during the duration of the application during the same insertion to allow permanent hair removal while reducing pain perceived by the patient. Advantageously, the modulation in current intensity is carried out discontinuously, according to a series of Duration sequences varying from a fraction of a second to several seconds, the current applied during each successive sequence being of constant intensity, this intensity being itself identical to intensities of previous sequences or different from them.
According to a particular embodiment, the duration of the sequences and the intensity of each current applied during each sequence are preprogrammed.
