Liquid Nitrogen Treatment

Liquid Nitrogen (LN2) treatment is used to treat both benign and pre-malignant growths. Most common items treated with liquid nitrogen include:

  • Warts
  • Molluscum contagiosum
  • Seborrheic keratoses
  • Actinic keratoses
  • Brown spots

Risks of Liquid Nitrogen Cryotherapy

The main risks of liquid nitrogen treatment include the following:

  • Pain
  • Blistering
  • Scarring
  • Hyperpigmentation
  • Hypopigmentation
  • Failure to remove the lesion
  • Need for future treatments

When a lesion is treated with liquid nitrogen, the lesion may or may not blister within the following 1-2 days. It is fine to puncture the blister with a needle and keep the area wrapped with a bandage. There will be crusting/scabbing that will be present for 1-2 weeks after the treatment and will spontaneously fall off. Care must be taken to allow the scab to remain on the site as long as possible. As long as the scab is present on the site, the risk of significant discoloration or scarring lessens (although present).
