Seborrheic keratoses can be removed using a laser, an intense beam of light that burns and destroys the growth. Laser light cleans (sterilizes) and seals as it cuts tissue, which reduces bleeding, pain, and healing time.
A laser procedure may be done in your doctor's office or clinic. Numbing medicine isn't usually needed. But if it is needed, a topical anesthetic may be put on your skin to numb the area. After laser treatment, the wound will be painful for a few days. Your doctor will give you instructions on how to clean and care for your wound.
Laser treatment normally causes no scarring. But it can cause permanent skin lightening.
