Treatment depends on the technique being used. Cryotherapy uses controlled freezing, while electrodessication and curettage uses electrical energy and scraping to remove the abnormal tissue. Topical chemotherapy involves applying medication directly to the affected area.

After treatment, the area may become red, swollen, tender, crusted, or blistered as it heals. Your dermatologist will provide specific aftercare instructions and advise you on what to expect during the healing process.
