What effect do UV rays have on the skin?

UV rays can have a significant impact on the skin, primarily through their damaging effects on skin cells. Prolonged exposure to ultraviolet radiation can lead to DNA damage within the skin cells, which may result in mutations. These mutations can accumulate over time, significantly enhancing the risk of developing skin cancers, including melanoma, basal cell carcinoma, and squamous cell carcinoma.

Additionally, UV rays contribute to premature skin aging, manifesting as wrinkles, loss of elasticity, and changes in skin texture and tone. They can also cause sunburns, further indicating the harmful effects this radiation can have on skin health. Understanding this risk is crucial for practicing proper sun safety measures, such as wearing sunscreen, protective clothing, and seeking shade, especially during peak sunlight hours.

The other choices suggest positive effects of UV exposure on the skin or imply a lack of risk, which do not align with the well-documented scientific understanding of UV radiation and its effects on skin health.
