Freezpen® Cryotherapy Treatment is a procedure that uses extreme cryogenics technology to destruct unwanted tissue, including warts, keratoses, skin tags, cherry hemangiomas, etc. The Freezpen® uses a high-powered microjet to achieve a temperature of -89°C and complete tissue necrosis in seconds. As the tissue cells rapidly drop to a lower temperature, the area freezes and turns white. The targeted unwanted cells are destroyed and formed ice crystals. Water then fills the surrounding area to create blisters. Blisters will be ruptured naturally within 24- 48 hours while small wounds will heal within 2 to 4 weeks.
