Cryotherapy

The rapid freezing rate of the FreezPen is based on The Joule-Thomson (JT) effect. This is a thermodynamic process that occurs when a fluid expands from high pressure to low pressure. FreezPen cryotherapy utilizes a cryogenic gas called Nitrous Oxide (N2O) which is compressed at 725 PSI (very high pressure). When nitrous oxide is released from the FreezPen as a jet of gas, it expands at -89°C and immediately freezes the affected lesion.

The mechanism of action behind FreezPen is simple and highly effective: application of extreme cold in a rapid freezing rate in order to freeze and destroy the lesion. The unique applicator’s tip creates a focused, high-pressure jet of extremely cold nitrous oxide gas that is targeted at the lesion. The temperature of the lesion drops to -89°C within seconds, causing the water inside the cells to freeze, expand and rupture the membranes of cells. As a result, the cells that form the lesion are destroyed and eliminated by the body over time, to allow a new healthy skin to grow in the same location.

FreezPen cryotherapy is a non-invasive treatment that involves minimal discomfort and does not require anesthesia or stitches. FreezPen treatment has no downtime and it significantly reduces the risk of scars and other complications. Treatment is quick and does not require special post-op care.

Your lesion is expected to fall off 2-4 weeks after the treatment. Some lesions are more persistent and may take longer to disappear

Most lesions require one treatment. Large lesions, such as warts, may require 1-2 follow up treatments.

Generally, there is no post-treatment care regime and you may resume your daily activities immediately after the treatment. We do advise clients to apply Vaseline on the area of the treatment to speed up the healing process.
