Sunscreen: Difference between revisions

UVA rays make up over 95 percent of UV rays that reach the surface of the earth.  People are exposed to them every day and throughout their lifetime.  They are longer UV waves.  UVA rays are less intense than UVB rays, but they penetrate deeper into the skin.  Studies have shown that UVA rays damage skin cells where most skin cancer develops.  These rays are the most used ray within tanning outside or in salons.  Tanning Booths are by far the more dangerous than sunbathing in the outdoors.  In a tanning booth, people are twice as likely to develop skin cancer and the UVA rays emitted in the tanning salons are that of twelve times the sun.  They also increase a person’s melanoma risk by seventy-five percent.
