ABSTRACT:
A process for the removal of superficial epidermal skin cells in the human skin. A contaminant having a high absorption at at least one wavelength of light is topically applied to the surface of the skin. Some of the contaminant is forced to infiltrate into spaces between the superficial epidermal cells. The skin section is illuminated with short laser pulses at the above wavelength, with at least one of the pulses having sufficient energy to cause some of the particles to explode tearing off the superficial epidermal skin cells. In a preferred embodiment, the contaminant includes 1 micron graphite particles and the laser used is a Nd:YAG laser.
