What is the result of UV exposure to the skin over time?

1. Increased production of hemoglobin

2. Thinning of the stratum corneum

3. Increased risk of skin cancer

4. Enhanced production of collagen

The correct answer is: Increased risk of skin cancer

Over time, exposure to ultraviolet (UV) radiation has significant effects on the skin, particularly contributing to an increased risk of skin cancer. UV radiation can damage the DNA in skin cells, leading to mutations that can result in malignant growth. The cumulative effect of repeated UV exposure is particularly concerning as it can lead to various forms of skin cancer, including basal cell carcinoma, squamous cell carcinoma, and melanoma. While other responses touch on skin characteristics, they do not directly relate to the long-term consequences of UV exposure in the same critical way. Increased production of hemoglobin is more associated with other factors, such as response to oxygen levels, and not primarily linked to UV exposure. Thinning of the stratum corneum does not reflect the typical response of the skin to UV exposure; rather, the stratum corneum often thickens as a protective measure against UV damage. Although collagen production is important for skin health, enhanced production as a result of UV exposure is misleading, as UV can, over time, degrade collagen, leading to premature aging rather than enhancing its production.
