A method for the superficial healing of tissue with the aid of a pulsed light source, in which method a series of light pulses are applied to the surface of the tissue, wherein a light source with a wavelength of which the light is absorbed mainly in the region at the surface of the skin which lies above a tissue depth of 50 µm is used, wherein a first part of the series of light pulses is configured such that rapid heating of the surface of the skin and then, after a time delay, heating of regions of tissue lying beneath this region of the surface of the skin to a prescribed target temperature is achieved by heat conduction without tissue removal, and wherein a subsequent part of the series brings about an oscillation of the temperature of the regions of tissue about a value lying slightly below the target temperature.
L'invention concerne un procédé et un dispositif pour chauffer superficiellement un tissu au moyen d'une source lumineuse pulsée. Selon l'invention, une série d'impulsions lumineuses est appliquée sur la surface du tissu. La première partie de la série est conçue de sorte que l'on obtient un chauffage rapide de la surface et, par conséquent, un chauffage, par conduction thermique, de zones de tissu situées sous la surface du tissu, à une température cible prédéterminée, sans enlèvement de tissu. La partie suivante de la série provoque une oscillation de la température des zones de tissu situées sous la surface du tissu, autour d'une valeur légèrement inférieure à la température cible.
