Skin surface peeling process using laser
First Claim
1. A process for the removal of superficial epidermal skin cells in human skin comprising the steps of:
- a. topically applying to a section of said skin a contaminant having a high absorption at at least one frequency band of light which penetrates the outer layers of human epidermis,b. forcing some of said contaminant to infiltrate into spaces between said superficial epidermal skins cells, andc. illuminating said section of skin with pulses of said at least one frequency band of light, at least one of said pulses having sufficient energy to cause at least a portion of said contaminant to explode so as to tear off some of said superficial epidermal skin cells.

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.
