Abstract:
1. A method for reducing skin wrinkles comprising the steps of: generating a pulsed beam of laser radiation from a YSGG gain medium, said beam of radiation having a wavelength of 2.79 microns; and scanning the pulsed beam over the skin in a two dimensional array of spots within a treatment region in a manner such that the spots overlap, with the fluence at each spot being between 2 and 5 joules/cm2 and with the pulse width being between 100 and 600 microseconds and wherein the fluence and pulse width are selected to ablate the upper surface of the skin to a predetermined depth and to create a layer of coagulated tissue below the ablated region with the thickness of the layer of coagulated tissue being at least as great as said predetermined depth of ablation, said coagulated tissue creating a natural dressing which subsequently peels from the skin resulting in a reduction in skin wrinkles.
