Sun damage, or photo damage, is an ever-growing skin condition that is caused by exposure to the sun. Sun damage is the leading cause of skin aging and results in wrinkles, fine lines, and brown spots. With too much exposure, your skin begins to appear leathery and loses its natural texture, tone, and glow.
What Are the Signs of Sun Damage?
Sun damage causes several changes in your skin. The first, and most common sign, is a sunburn. A sunburn is actually an injury to your skin caused by sun damage. Another common sign of sun damage is dry skin. Sun exposure robs your skin of moisture and oils, leaving it dry, flaky, and prematurely wrinkled.
Over time, your skin loses the underlying structure of collagen. Collagen is a protein-based lattice-work that provides support to your skin. As your collagen is destroyed by sun damage, this foundation weakens and disappears, leaving your skin sagging and wrinkled. Actinic keratosis is a precursor to skin cancer that is caused by photo damage. This condition appears as pink, red, yellow, or brownish patches on your skin and needs to be medically treated.
