<p>A cooling method and apparatus for use in combination with a laser for long-term hair removal and skin peeling. The cooling may be used with such hair-removal or skin peeling, with or without a contaminant that absorbs laser energy. Either concurrently or approximately concurrently with the illumination, the skin surface is cooled so that skin tissue is maintained at temperatures below that which could cause tissue damage. Preferably, the cooling is applied as cryogenic blasts of a cooling medium, e.g. a refrigerant, nitrogen, or cooled air, and may be performed in a cyclical fashion with heating form laser illumination. Optionally, the cooling method and apparatus may be used with an impingement technique and associated device for breaking up the formation of fluid vapor layer immediately above the skin surface for better control of the cooling process.</p> |
