    摘要: A method for eliminating unwanted hairs is provided. The method includes applying an effective amount of a composition including microparticles to the surface of the skin where the hairs are situated and removing the composition remaining on the surface of the skin. The microparticles contain chromophores and a second material different from the chromophores. At least 80% by weight of the microparticles have a diameter of between 3 &mgr;m and 10 &mgr;m. A composition containing a solvent which dissolves the chromophores may then be applied to the surface of the skin. Laser radiation is then applied in one or more shots. The emitted wavelength of the laser radiation is absorbed by the chromophores. The light energy and the emission duration of the laser energy are sufficient to damage and/or kill the cells responsible for the growth of the hair.

    摘要: Mammalian skin is treated and advantageously smoothed, for example to remove wrinkles, lines, warts and scars therefrom, by topically applying thereto a composition which comprises at least one laser-absorbing chromophore formulated into a physiologically acceptable carrier, diluent or vehicle therefor, and laser-irradiating the skin thus treated with an intensity sufficient to locally convert the light energy into heat energy in the applied composition and advantageously effecting tissue ablation of the surface of the treated skin, said applied composition and the thickness thereof having an absorbance at the emission wavelength of the laser such that the light energy transmitted into the skin generates no undesired irreversible tissue or cell damage.
