Cryotherapy

Cryotherapy is one of the most frequently applied treatment methods in dermatology. In this method, liquid nitrogen is used to freeze the affected tissue in a controlled way so that it is removed over time by the healthy skin.

Cryotherapy can be safely applied in the treatment of warts, actinic keratoses caused by chronic sun damage, seborrhoeic keratoses, skin tags and certain benign skin lesions deemed appropriate.

The procedure is usually completed within a few minutes. A brief sensation of pain, burning or stinging can occur during application. After treatment, redness, mild swelling, blistering or crusting can develop at the application site. These findings are part of the expected healing process and usually resolve on their own within a few days to a few weeks.

Where necessary, more than one session can be applied to the same lesion. The number of sessions is determined according to the type, size and location of the lesion. Not every skin lesion is suitable for cryotherapy; the decision to treat is made after the characteristics of the lesion have been assessed by dermatological examination.
