UV exposure has significant effects on skin health, and one of the most serious consequences is its potential to lead to premature aging and skin cancer. The ultraviolet (UV) rays from the sun can damage the DNA in skin cells, which may result in mutations that lead to skin cancer over time. Additionally, UV exposure accelerates the breakdown of collagen and elastin fibers in the skin, leading to signs of aging such as wrinkles, sagging, and loss of elasticity.

This understanding is crucial for both clients and professionals in the cosmetology field, as it emphasizes the importance of sun protection measures to maintain skin health. While certain other options touch on aspects of skin appearance and health, they do not directly address the severe implications of UV damage like skin cancer and premature aging do. Proper education about UV exposure risks allows individuals to make informed decisions about sun protection and skin care practices.
