What effect do ultraviolet rays have on the skin?

Ultraviolet (UV) rays have a significant impact on the skin, and the correct response identifies their potential to cause skin damage and increase the risk of skin cancer. UV rays penetrate the skin layers and can lead to various detrimental effects such as DNA damage in skin cells, which contributes to premature aging and the development of multiple skin conditions, including melanoma and non-melanoma skin cancers.

The harmful effects of UV radiation arise from both UVA and UVB rays. UVA rays are primarily responsible for photoaging and can penetrate deep into the skin, while UVB rays are more associated with sunburn. Both types of UV radiation can trigger an inflammatory response, leading to further skin complications.

Understanding the dangers of UV rays is critical for making informed choices about sun protection and skin health. This knowledge emphasizes the importance of using sunscreen, seeking shade, and wearing protective clothing to mitigate these risks.
