Cryotherapy for suitable lesions

Cryotherapy is a quick, non surgical treatment that uses liquid nitrogen to freeze targeted skin cells. It is commonly used for a range of superficial lesions such as viral warts, actinic keratoses, some seborrhoeic keratoses and selected other benign growths.

How cryotherapy works

Liquid nitrogen is applied to the lesion using a spray or a cotton tipped applicator. The rapid freezing and thawing damages the abnormal cells, which then shed over time as the skin heals.

  • Short treatment time, typically a few seconds per lesion
  • Performed without local anaesthetic
  • Can be repeated at intervals if required

Lesions suitable for cryotherapy

Cryotherapy is commonly used for:

Not all lesions are suitable for freezing. Benign appearance must be confirmed first, and suspicious or invasive lesions are better treated with surgical methods.

What to expect after treatment

After cryotherapy the treated area may sting or burn briefly, followed by redness and mild swelling. A blister or crust may form and typically resolves over two to four weeks, leaving new skin underneath.

  • Temporary lightening or darkening of skin can occur
  • A small flat scar is possible
  • Occasional retreatment may be needed
