Sun damage, also known as photoaging, results from prolonged exposure to ultraviolet (UV) radiation, leading to premature aging of the skin. Symptoms include wrinkles, fine lines, hyperpigmentation (sunspots), and a loss of skin elasticity. Long-term sun exposure also increases the risk of skin cancer. Prevention and management involve using broad-spectrum sunscreens, wearing protective clothing, and seeking shade. Treatments for existing damage may include topical retinoids, antioxidants, chemical peels, and laser therapy.
