Skin aging includes intrinsic aging, a universal and inevitable process attributable to the passage of the time alone; and photoaging, changes attributable to chronic sun exposure, which are neither universal nor inevitable. The major clinical features of aging skin include xerosis, laxity, wrinkles, slackness, and the occurrence of benign neoplasms such as seborrheic keratoses and cherry angiomas. Photoaging is characterized by dryness (roughness), actinic keratoses, irregular pigmentation (freckling, lentigines, guttate hypomelanosis, persistent hyperpigmentation), wrinkling, stellate pseudoscars, elastosis (fine nodularity and/or coarseness), inelasticity, telangiectasia, venous lakes, purpura (easy bruising), comedones (maladie de Favre et Racouchot) and sebaceous hyperplasia.
