Cryotherapy Specialist Dermatologist in London
(Warts, Seborrhoeic keratosis and other lesions)

Cryotherapy is a safe and effective procedure that uses extreme cold to treat common skin lesions such as warts, seborrhoeic keratoses, and other benign growths. It is quick, minimally invasive, and usually performed in clinic under local anaesthetic when needed.

Dr Bryan McDonald, Consultant Dermatologist in London, offers precise cryotherapy treatments tailored to your lesion type and location.

​

What conditions can be treated with cryotherapy?

• Seborrhoeic keratoses (benign “age spots” or “barnacles”)

• Viral warts

• Skin tags

• Small benign lesions causing irritation or cosmetic concern

How cryotherapy works

Liquid nitrogen is applied to the lesion, freezing it and causing the abnormal tissue to fall off over the following days. The procedure:

• Is quick, often under 10 minutes

• Usually requires minimal preparation

• Causes only mild discomfort (like a stinging or burning sensation)

• Leaves surrounding skin unharmed when performed by a specialist

What to expect after treatment

• Mild redness, blistering, or scabbing for 1–2 weeks

• Lesion usually falls off naturally

• Rarely, minor pigmentation changes may occur
