Sun Spots, Age Spots, and other Pigmented Lesions

Many people develop brown lesions of their skin from chronic sun exposure, time, and other factors. These can appear on the face, hands, upper chest, and other locations and tend to make the skin look prematurely old. In the U-M Cosmetic Dermatology and Laser Center, we have a variety of treatment options available to minimize these pigmented lesions. Often, patients elect to have these spots specifically removed with our Q-switched Alexandrite (AlexTriVantage) laser. This device specifically targets the brown color of the unwanted lesions. The laser is placed from spot-to-spot where it briefly flashes a light on the skin. Microscopically, the extra pigment within the brown lesions “shatters” and the body then reabsorbs it, lightening the spots. Each pigmented lesion will temporarily darken for a few days before becoming progressively lighter.

Alternatively, sun spots (lentigines) may be just one feature of sun damaged skin and the patient may elect to undergo laser resurfacing. Several devices are available in the CDLC to rejuvenate the skin, producing improvement in not only sun spots, but also wrinkles and other textural problems. Rather than targeting specific lesions, resurfacing procedures are applied over an entire portion of the skin’s surface (the entire face, for example) and are intended to blend texture and produce more uniform color.

To find the treatment that is right for your dark spots and skin, our expert physicians will discuss your choices in a consultation appointment.
