The CryoPen™ emits a fine jet of nitrous oxide under high pressure which reaches up to -89°C, 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. Procedures typically last from 5 to 25 seconds as the penetration of the cold is approximately 1mm per 5 seconds of treatment, so you can be in and out of the salon quickly. There is no downtime and it is advisable to leave the area uncovered to speed up the healing process. As long as you protect the area from abrasion or damage, there are no limitations to activities straight after the treatment e.g. work, swimming, bathing.
