ABSTRACT:
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.
