TREATS COMMON* LESIONS ON THE FACE AND BODY
• Dark spots • Age spots • Skin tags
• Warts • Moles • Fibromas
• Keratosis • Angiomas • Milia
• Molluscum • And more…
Before and Afters:
1. Rapidly and precisely freeze the unwanted lesion.
2. Water in the lesion cells will freeze, expand and rupture the cell membrane.
3. Targeted lesion cells are destroyed, and the lesion disappears after healing.
After the treatment, the lesion will gradually fall off, new skin forms and the area returns to its original colour.
FreezPen Cryotherapy Technology
What is cryotherapy?
Cryotherapy is a procedure that utilizes extreme cold to destroy unwanted tissue. The process is called “Cryo-necrosis” – tissue destruction by rapid freezing.
How is freezing achieved?
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.
How does FreezPen cryotherapy work?
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.
Liquid Nitrogen (N₂) is colder than Nitrous Oxide (N₂O). Does it mean that N₂ is more effective?
No, nitrous oxide (N₂O) is a safer alternative to liquid nitrogen (N₂) and yields similar results.
Cells destruction in all benign growths is achieved at -60°C. Both liquid nitrogen (-195°C) and nitrous oxide (-89°C) drop in-tissue temperatures to -60°C and lower within seconds. The excessive power of liquid nitrogen is more likely to cause unwanted collateral damage to surrounding healthy tissue. Liquid nitrogen increases the risk of pigmentation and other adverse effects, while FreezPen’s nitrous oxide allows high-precision treatments targeting only the lesion itself. This is a significant advantage when treating small lesions such as milia, molluscum contagiosum, small warts and moles, or when lesions are found around delicate areas.
Why is cryotherapy better than other methods of removing skin lesions?
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.
FreezPen Cryotherapy Treatment
What types of skin lesions can be treated with FreezPen?
FreezPen treats all types of common non-malignant skin lesions: warts, dark spots, liver/age spots, skin tags, moles, keratosis, angiomas, fibromas, milia, molluscum contagiosum and more. Please note that any types of malignant or suspicious growths need to be treated by a certified dermatologist.
How long will it take for the lesion to disappear?
Your lesion is expected to fall off 2-4 weeks after the treatment. Some lesions are more persistent and may take longer to disappear
How does the FreezPen treatment feel?
The treatment is comfortable and doesn’t hurt. It feels like a light pinch. There is no need for local anesthesia.
How many treatments are required?
Most lesions require one treatment. Large lesions, such as warts, may require 1-2 follow
How soon after the treatment can I return to my daily activity?
Immediately after. FreezPen treatments involve zero downtime.
Will the FreezPen treatment leave any scars on my skin?
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.
How many lesions can be treated in one session?
As many as you like. There is no limit on the number of lesions per session.
Can the FreezPen be used on children?
Yes, children are most commonly treated for warts and Molluscum Contagiosum. FreezPen cryotherapy is a tolerable modality suitable for both children and adults.
How long is the FreezPen treatment?
FreezPen treatment usually takes no more than a few minutes. The duration of the treatment depends on the number of treated lesions, the number of freeze-thaw cycles and the duration of freezing.
I discovered a new mole on my body. Can I remove it with FreezPen cryotherapy?
New skin growths (especially moles) are potentially malignant and need to be evaluated by a dermatologist first. Only stable lesions that are not evolving over time are suitable for cryotherapy treatments. Consult with a certified physician to make sure your new mole is a non-malignant growth before removing it with FreezPen.
I have a dark skin tone. Can I remove my lesions with FreezPen cryotherapy?
Yes, FreezPen treatment is safe for everybody.
What should I do after the treatment?
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.
Are there any side effects to the FreezPen treatment?
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.
