Sun damage refers to the harm caused to the skin by ultraviolet (UV) rays from the sun. This damage can lead to various skin issues, including sunburn, premature aging, and an increased risk of skin cancer. UV rays can break down collagen and elastin, essential proteins that keep the skin firm and elastic, resulting in wrinkles and sagging. To protect against sun damage, it is important to use sunscreen with a high SPF, wear protective clothing, and seek shade during peak sunlight hours. Regular skin checks can help identify any unusual changes, allowing for early detection of potential skin problems related to sun exposure.
