The Dermapen Cryo uses disposable cartridges of liquefied N2O to deliver quick, effective cryotherapy treatments to benign skin lesions. The nitrous oxide destroys tissues by freezing the intercellular fluid and forming ice shards and crystals that rupture the cells membrane, destroying the cells.
Because it delivers N2O directly onto the lesion and not the healthy surrounding tissue, it can safely treat lesions on the face and around the delicate eye area. Dermapen Cryo accurately delivers an ultra-cold, high pressure N20 jet directly onto the lesion, making it very effective. It is also very fast, with a penetration rate of 1mm per 5 seconds and able to penetrate to a depth of 5mm deep.
