What is one effect of UV radiation on human skin?

Enhanced elasticity

Scarring

Premature aging or skin cancer

UV radiation has a significant detrimental effect on human skin, primarily leading to premature aging and an increased risk of skin cancer. When skin is exposed to UV rays, it undergoes changes at the cellular level, such as the breakdown of collagen and elastin fibers, which are essential for maintaining the skin's firmness and elasticity. This breakdown results in visible signs of aging, including wrinkles, fine lines, and sagging skin.

Furthermore, prolonged exposure to UV radiation can damage the DNA in skin cells, which may lead to mutations and ultimately contribute to the development of skin cancers, including melanoma, basal cell carcinoma, and squamous cell carcinoma. This dual impact of UV radiation makes it crucial for individuals to take preventive measures, such as using sunscreen, wearing protective clothing, and avoiding excessive sun exposure to maintain skin health.
