What To Expect After Liquid Nitrogen Treatment

Liquid nitrogen is a freezing process in which an attempt is made to destroy abnormal tissue.

What Can I Expect?

Usually there is a burning sensation and a moderate degree of pain. Occasionally, the pain can be severe.
The treatment area becomes red and is often swollen. Swelling may take a few days to subside, especially around the eyes.
Occasionally, there will be blistering, sometimes even a blood blister. You may open any blister with a needle which has been placed in alcohol for a few minutes. The blister will be replaced by crusts or a scab after several days.
If the freezing was very light, there may just be darkening and then healing of the skin.

You should leave the area open to the air if possible. It may take 5-10 days for complete healing.
Healing time may take longer if the treated areas are deep or large.
Your skin may feel tight during this healing process.
As the crust begins to separate at the edges, occasionally a clear fluid may escape from beneath. This is normal and does not indicate infection. (If this occurs, you should apply antibiotic ointment such as Polysporin). After the crust comes off, you may have some redness for several weeks, depending on your healing process. Don't peel the scab.
You may notice a darkening or lightening of the pigment in the areas where the liquid nitrogen has been used. This may be temporary or permanent.
Please do not hesitate to contact your dermatologist if you have concerns or questions.
