Abstract
Aging is attributed to both intrinsic and extrinsic processes.1 Photoaging—the most recognized form of extrinsic aging of the skin—describes changes brought about by long-term sun exposure, resulting in photodamage.2 Photodamage, therefore, refers to the physical and morphologic alterations secondary to solar UV exposure and is the main component of photoaging.3 Intrinsic aging of the skin is characterized by finely wrinkled skin, cherry hemangiomas, and seborrheic keratoses.4 Photodamage, however, includes other characteristics, such as coarsely wrinkled skin, hyperpigmentation, hypopigmentation, and telangiectasia,1,5,6 and has been associated with the development of malignant neoplasms.2Keywords
