The cryo-pen emits a fine jet of Nitrous Oxide under high pressure, which allows the clinician to work with millimetre precision. This destroys the tissue by freezing the inter-cellular fluid, forming ice shards and crystals which rupture the membrane, thereby destroying the cell.
That means there will be no collateral damage to healthy tissue. It’s so incredibly accurate and practical.
The procedure is virtually painless and safe for all skin types and skin tones.
