It's a skin care procedure usually performed by a specialist. They'll use a spray, cotton swab, or metal device called a cryoprobe to apply extremely cold liquid nitrogen. This freezes the cells and the immediate surrounding cells. The frozen skin thaws and forms a scab, which eventually falls off.

It might be used to treat an assortment of skin conditions just as:

  • Warts
  • Skin Tags
  • Moles
