The brown spots on skin have many names such as age spots, liver spots, sun spots, skin discolorations, hyperpigmentation or freckles. While these spots are harmless, many people also think they are unsightly. These spots usually start to appear after age 50 and grow larger as a person ages. Brown spots most frequently appear on the face, the scalp and the hands. The main cause of the brown spots is too much exposure to the sun. Prevention is accomplished with sunscreen and sunblock. But there are several laser treatments to treat brown spots that reduce their appearance or to remove them. Brown age spots often disappear with a single laser treatment. Let your face, legs, hands, and other areas look ageless.
