Sun exposure causes cumulative skin damage and aging

Accumulated solar exposure throughout a person's life can lead to long-term dermatological issues, including dark spots, wrinkles, loss of firmness, and an increased risk of skin cancer. This process, known as photoaging, occurs because ultraviolet radiation causes oxidative stress and damages cellular structures, specifically degrading collagen and elastin fibers.

Many skin changes observed in adulthood are linked to excessive sun exposure during childhood and adolescence. Common manifestations include brownish spots, deep wrinkles, irregular texture, visible blood vessels, and loss of luminosity. To manage and prevent these issues, dermatologists recommend consistent use of sunscreen, including tinted versions to help unify skin tone, and regular hydration to repair the skin barrier damaged by radiation.
