Cryotherapy using Liquid Nitrogen (LN2) is a treatment that involves freezing skin lesions to remove them. It is commonly used to treat warts, skin tags, actinic keratosis, and other benign lesions.
Liquid Nitrogen (LN2)
No special preparation needed.
During the treatment, liquid nitrogen is applied to the lesion using a spray device or cotton swab. The freezing process destroys the targeted tissue, which will slough off over time.
Avoid picking at the treated area and keep it clean. Follow specific aftercare instructions provided by the physician.
Is cryotherapy safe?
Yes, it is safe when administered by certified dermatologists.
How long does it take to see results?
Results can be seen within a few days to weeks as the lesion falls off and the skin heals.
Does the treatment hurt?
There may be a brief stinging or burning sensation during the freezing process, but discomfort is generally minimal.
Are there any side effects?
Common side effects include redness, blistering, and temporary skin discoloration, but these are usually temporary.
