Sun damage is the harm caused to the skin by repeated or prolonged exposure to the sun’s ultraviolet (UV) rays. These rays penetrate the skin and can damage skin cells, even on cloudy days or without visible sunburn. Over time, sun exposure breaks down collagen and elastin, which are essential for firm, healthy-looking skin.

The effects of sun damage include sunburn, dark spots, uneven skin tone, wrinkles, dryness, and loss of elasticity.
