Laser treatment of pigmentation associated with photoaging

Cumulative exposure to the sun can induce clinical and histological changes in the skin, commonly called photo- aging or dermatoheliosis. This occurs primarily in patients with fair skin types (Fitzpatrick 1 to Fitzpatrick 3 skin types) who have experienced repeated solar injuries over the years, such as lifeguards and outdoor laborers. 1 Clinically, photoaging represents a polymorphic response to sun damage that manifests variably as wrin- kles, skin roughness and xerosis, irregular mottled pig- mentation, telangiectasias (poikiloderma of Civatte), actinic purpura, sallowness (also known as Milian citrine skin), and brown macules or solar lentigines.
