Aging of the skin is a direct result of spending too much time in the sun. Wrinkles, age spots, shingles, and tanning are some common long and short term effects. So why exactly are these things so bad?
Wrinkles are caused by the UVA rays. Skin wrinkles because the UVA rays penetrate deep into the layer of skin which is known as the elasticity layer. The layer is weakened by receiving too much UV light over a long period of time. Wrinkles usually have a leathery appearance and give the skin a rough texture.
Age spots, also known as “liver spots,” are flat brown spots which are caused by many years of exposure to the sun. They usually develop on fair-skinned individuals who are in the sun often. Another type of skin aging is shingles. Shingles are an outburst of a rash or blisters that can cause grave pain. Finally, tanning is a negative effect of the sun on the skin. Tanning is the skin’s natural defense mechanism against UV light to prevent sunburns. A common saying in Australia sums it up, “Slip, Slop, and Slap,” Slip on a shirt, slop on sunscreen, and slap on a hat. As long as you protect your skin and use your common sense when outdoors, your skin will benefit and remain healthy.
