Cryotherapy is a mode of treatment that involves the use of Liquid Nitrogen at temperature of minus 196 degree Celsius to treat various skin conditions.
The Liquid Nitrogen is generally used in the form of a spray.
It can be used to treat various skin conditions like warts, keloids, pyogenic granulomas, cherry angiomas, pre-cancerous skin conditions, basal cell skin cancer and genital warts, to name a few.
The treatment works by causing freeze-death of diseased tissue, allowing healthy tissue to grow in its place as the skin heals.
The treatment is simple, quick, has good cosmetic results and is relatively inexpensive.
The cold spray stings, and there may be redness and pain for a few hours. Aggressive therapy can lead to blister formation, and that is often a part of the treatment itself.
