Abstract:
A method for preparing the skin for treatment of cutaneous or subcutaneous compounds, comprising the steps of:a) focusing a laser beam with sufficient energy fluence to alter the skin at least as deep as the stratum corneum, but not as deep as the capillary layer;b) firing the laser to create a site of alteration, the site having a diameter of between 0.5 microns and 5.0 cm;c) applying a dye, a compound that alters the optical properties of stratum corneum, or a compound that stimulates the body's production of molecules that are strong absorbers of light; andd) firing a second laser with a wavelength that is absorbed by the applied dye, the compound that stimulates the optical properties of stratum corneum or the compound that stimulates the body's production of molecules that are strong absorbers of light.
