Lentigenes (brown spots) form as a result of sun exposure and time. Depending on the number of brown spots, their darkness, and the color of background skin, an individualized treatment strategy can be formulated. Treatment options include topical bleaching creams (which gently lighten brown spots over weeks to months), pigmented laser treatments (which lighten or remove most brown spots after 1-3 treatments), and laser skin resurfacing (which removes most brown spots in a single treatment).
