Age spots are also called seborrheic keratoses. Prior to treatment, a skin CT or dermoscopy can be performed to confirm the diagnosis and rule out associated conditions such as flat warts. In terms of treatment, cryotherapy, laser or surgical options are available. Freezing involves applying liquid nitrogen to the patches to dislodge them, and usually lasts about 10 days. Surgery is a surgical procedure that removes the plaque and sends it to a pathology lab for lab tests to clarify that it is an age spot and then other treatments, such as with laser therapy, can be performed. The laser is used to cauterize the spots with carbon dioxide laser to achieve the purpose of treatment.
