Laser light treatment is a flash, similar to a camera flash. The frequency of that light is best absorbed by the dark pigmented spots in the skin. The surrounding light skin, which is not pigmented, does not pick up that light very well, so the dark pigmented cells absorb virtually all of the light’s energy and simply peel off after a few days. The laser treatment itself takes approximately 30-minutes and is mildly uncomfortable. The sensation you feel is similar to a rubber band snapping on your skin. One treatment is often enough to be effective, but some people may want to do as many as three treatments depending on the level of sun damage. It’s not uncommon for people to have brown spots on their hands, arms or face. The pigment is consistent and you usually can’t feel them because they’re flat, not raised. These brown spots are often referred to as age spots, liver spots or sun spots. In medical terms, these brown spots are known as lentigines, which are basically sun spots caused by damage to the skin. Lentigines tend to make our skin look weathered, old and unsightly.
