The Photoderm is used to rejuvenate the skin. This typically requires a series of 5-7 treatments, and will remove red blotchiness, blood vessels, irregular pigmentation and fine lines from the skin. Some studies indicate it may also reduce pore size. These treatments can also be used to treat sun damage on the neck and chest. Occasionally brown spots or freckles may appear temporarily darker, but this will fade over 10 days with a resulting reduction of the pigmentation. This application can also be used to treat melasma, or the brown pigment that women can get from elevated estrogens.
