Signs of Sun Damage
Sun damage occurs from repeated exposure to UV radiation and is gradually revealed over time. The following are the four most common signs of sun damage to the skin.
1. Age spots and uneven pigmentation
Age spots, also known as liver spots or sun spots, form when the body increases its melanin production in response to sun exposure. Melanin then clumps together to form brown, black or grey spots on the skin, causing uneven skin tone in sun-exposed areas.
2. Texture changes
Thick, leathery skin is a telltale sign that someone has spent too much time in the sun. The classic Western cowboy with his tanned and leathery skin is the perfect example of how constant sun exposure can transform the skin.
3. Wrinkles and fine lines
Overexposure to the sun depletes your skin of collagen, elastin, and natural oils, which give the skin a youthful firmness and elasticity. As collagen and elastin break down, wrinkles appear and the skin begins to sag. The depletion of natural oils contributes to skin dryness, which accelerates the wrinkling process.
4. Broken capillaries
Repeated exposure to UV radiation can also cause the walls of tiny blood vessels (capillaries) to break down, causing red lines to appear on the skin. When several capillaries break down in the same area, such as around the nose or chin, the skin may appear reddened or flushed.
