L'invention concerne un procédé d'épilation à des fins essentiellement cosmétiques consistant à diffuser à travers la peau une lumière laser dont la longueur d'ondes cible le sébum trouvé dans le follicule et recouvrant le poil, à chauffer le sébum transférant la chaleur d'abord vers le poil puis vers sa racine, puis vers la papille et les vaisseaux sanguins papillaires via l'acheminement et la destruction du poil par photothermolyse sans pour autant abîmer la peau ou les tissus adjacents.
