Liquid Nitrogen is a tool used in dermatology to destroy skin cells. Proper care after liquid nitrogen treatment can reduce the risk of scar and discomfort. There is always a risk of blistering, scar and permanent skin discoloration after a spot (lesion) has been treated with liquid nitrogen.
The most wound site may be uncomfortable for 10-15 minutes after liquid nitrogen treatment. Some treatment sites may continue
Sometimes blisters can form. These may be either clear or blood blisters. When possible, leave blisters intact.
The skin may develop a scab over the first few days to weeks. Do not pick at the scab as this will increase the risk for scaring.
It is not uncommon to notice color changes of skin after liquid nitrogen treatment. It is extremely common to notice pink discoloration for a month after liquid nitrogen treatment. Sometimes this color change can last for months. Some color changes are permanent.
Most treatment sites require little care. You can apply aquaphor or vaseline if you notice scab formation. DO NOT PICK. If you develop a blister and the blister breaks, apply Aquaphor and a bandage until the site has healed.
If the medical provider has asked you to monitor the site, please contact your medical provider if the concerning spot has not resolved within 4 weeks of treatments.
