Cryotherapy is used to treat various skin lesions by freezing and injuring the surface layer of skin with Liquid Nitrogen. Normal skin healing then occurs.

The symptoms and signs of Cryotherapy are very similar to sunburn:

• Stinging can occur up to an hour with moderate discomfort afterwards
• The area becomes red and  swollen and may form a small blister
• The treated areas do not need to be covered. Shower as normal.
• A scab will form and drop off by  2-6weeks

• Blisters can become painful and uncomfortable

• It is best NOT to burst them
• If PAINFUL, they can be burst with a small needle
• If they do burst, a bandaid / dry dressing can be applied for a couple of days

Infection can occur, so it is important to check if:

• The surrounding skin is becoming increasingly tender to touch
• The redness is more than 1cm from the treated area
• The redness is increasing

General Notes for Wound Healing:

• Daily showers aid the healing process.
• AVOID using Soaps / Creams / Liniments / Antiseptics (eg – Betadine™, Savlon™, Dettol™)

• DRY dressings minimise the risk of infection.
