Tanning is a result of the skin repairing itself due to exposure of UVB and UVA rays, whether it be from direct sunlight or artificial means. When the skin receives UVA rays, it oxidises the melanin that is already present on the skin. The result is a darker color appearing on the skin. When the UVB rays are absorbed by the skin, damage occurs and melanin is produced, making the skin even darker. This is the reason that tanned skin will be darker 2 or 3 days after exposure. http://www.tanningtraining.com/btc/ch4.html?prodid=2 While tanning can be dangerous, while done in moderation and properly it can be done by much safer means.

Times have changed and tanning has become more of a trend even if it does promote skin cancer and premature aging. http://www.skincarephysicians.com/agingskinnet/basicfacts.html
