Frequently Asked Questions

 The mechanism of action behind FreezPen is simple and highly effective: application of extreme  cold in a rapid freezing rate 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 treats all types of common non-malignant skin lesions: sun spots, age spots, skin tags,  warts, and other benign lesions. Please note that any types of malignant or suspicious growths  need to be treated by a certified dermatologist. Any mole will need to be cleared by a doctor  and noted that it is benign.  

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

  The treatment is comfortable and doesn’t hurt. It feels like a light pinch. There is no need for  local anesthesia.

 FreezPen cryotherapy is the safest modality for the removal of unwanted skin growths. Since  FreezPen treatments are non-invasive and precise, the risk of scars and infections is significantly  diminished when compared to other invasive treatments.  

 Generally, there is no post-treatment care regime, and you may resume your daily activities  immediately after the treatment. We do advise patients to apply healing ointments (such as  Aquaphor) on the area of the treatment to speed up the healing process.  

 Although FreezPen cryotherapy is the safest treatment today for the removal of skin lesions, a few rare  side effects may still occur. These side effects include:  Pigmentation – Temporary pigmentation is rare but possible, because melanocytes are more susceptible  to sub-zero temperatures. FreezPen minimizes the risk of collateral damage to healthy skin tissue, so the  risk of pigmentation is minimized as well.  Blisters – temporary blisters may appear in the lesion area due to fluids that are released from destroyed  lesion cells.  Hair loss – like melanocytes, hair follicles are more susceptible to sub-zero temperatures. Hair follicles in  the treated area are more likely to be affected, thus hair may not grow back in the area of the lesion  after cryotherapy.
