Which of the following factors can contribute to extrinsic aging?

Genetics
Sun exposure
Cellular metabolism
Dietary habits

The correct answer is: Sun exposure

Extrinsic aging refers to the aging process influenced by external factors, primarily environmental elements. Sun exposure is a significant contributor to extrinsic aging, as ultraviolet (UV) radiation from the sun can lead to premature skin damage. This damage manifests as fine lines, wrinkles, loss of skin elasticity, uneven pigmentation, and a rough texture. Over time, excessive sun exposure can increase the risk of skin conditions, including skin cancer. While genetics, cellular metabolism, and dietary habits do play roles in the overall aging process, they are typically associated with intrinsic aging, which pertains more to internal biological processes controlled by factors like genetic makeup and cellular health. Recognizing the influence of sun exposure emphasizes the importance of protective measures such as wearing sunscreen, seeking shade, and wearing protective clothing to mitigate harmful effects and promote healthier skin as one ages.
