Cryopen is an advanced cryo therapy innovation that is a fast effective, safe and new solution for the removal of skin imperfections. The cyropen emmits a fine jet of nitrous oxide under hi pressure which allows the clinician to work with milimeter precision. This destroys the tissue by freezing the intercellular fluid, forming ice shards and crystals which ruptures the membrane, thereby destroying the cell. That means there will be no collateral damage to healthy tissue. Its so incredibly accurate and practical.
