“The PRO-U™ EPID-COOLING SYSTEM is not in skin contact with the skin surface. Rather, liquid drops of cryogen are sprayed onto the skin surface. The cryogen used is a non-flammable, environmentally compatible freon substitute. The cryogen forms a liquid pool on the skin surface. The temperature of the pool is between minus 30 - minus 60 degrees centigrade. That is obviously far below the "frostbite" temperature mentioned above. The cryogen subsequently evaporates and removes heat from the skin. Because the spurt durations are so short, the cooling remains confined to the epidermis and does not affect the temperature of the underlying port wine stain blood vessels. This spatial selectivity of the cooling is what allows much higher laser light dosages to be used while at the same time minimizing injury to the skin. ”
