What can excessive UV exposure lead to?

Excessive UV exposure is known to have harmful effects on the skin, one of which is skin aging. This occurs because ultraviolet (UV) rays can damage the skin's collagen and elastin fibers, which are critical for maintaining skin elasticity and firmness. Over time, the accumulated damage from UV exposure can result in premature aging signs such as wrinkles, fine lines, and loss of skin tone. This is often referred to as photoaging, which drastically alters the skin's appearance, making it appear older than it actually is.

While other options mention smoother skin, increased collagen, and allergic reactions, they do not accurately reflect the well-documented consequences of excessive UV radiation, which primarily includes skin damage and aging. Understanding the role of UV exposure is vital for making informed decisions about tanning practices and protecting skin health.
