The sun does a lot of good for our body – It stimulates the body’s production of vitamin D, and it regulates sleep cycles. But there’s also a downside: can cause sun burn, wrinkles and skin cancer.
Every time the sun strikes your skin, Melanin a pigment is released by skins epidermal layer of cells. Melanin protects skin from the sun’s ultraviolet rays, which can burn the skin, and over time, could reduce its elasticity and cause a person to age prematurely. Sun-tanning occurs because exposure to sunlight causes the skin to produce more melanin and to darken. The tan fades as these cells move toward the surface and are sloughed off.
Too much exposure to ultraviolet or UV rays can cause sunburn. UV rays penetrate the outer skin layers and pass into the deeper layers, where they can damage or kill skin cells. People who do not have much melanin and sun burn easily should protect themselves by covering up sensitive areas, wearing sun block, limiting their total exposure time, and limiting their sun exposure.
Sun radiations cause most of the skin changes that we think of as a normal part of aging. Over time, the sun’s ultraviolet (UV) light damages the fibers in the skin called elastin. When these fibers break down, the skin begins to sag, stretch, and lose its ability to go back into place after stretching.
In some cases sun damage to the skin may not be apparent when you’re young, however it may show later part of the life.
