Skin Aging

Premature aging (or photoaging) is characterized by wrinkles, age spots, sagging skin and leathery skin. Photoaging is primarily due to the damage of UV radiation exposure from the sun over time.1 The effects of photoaging depend on the degree of UV radiation exposure and the skin pigment.2 Skin aging caused by UV rays can be avoided by protecting your skin from the sun.
