Risks or Side Effects
Patients should expect some degree of swelling and blistering at the treatment site, depending on the length of freezing and number of cycles carried out. There may be mild pain or itching, both of which will improve as the lesion heals. Skin discoloration (usually a lack of pigment, known as hypopigmentation) may occur, which can be permanent in some cases or slowly fade away after a few weeks to months.
