The Rise of Indoor Tanning beds

The social desirability of a tan is a modern phenomenon, beginning in the 1920s when the French designer Coco Chanel decreed it as a fashion look. The concept of obtaining a tan without going outdoors became increasingly attractive. However, early indoor tanning units emitted the most damaging portions of the ultraviolet spectrum, UVC and UVB, and were plagued by safety problems. In the 1970s, medical devices that emit principally UVA were developed and quickly adopted for modern indoor tanning. The biological effects of UVA were less obvious than those of UVB, which is responsible for skin reddening, or UVC and these devices were touted as offering a "safe" tan.

It soon became apparent that UVA exposure could cause the same problems as UVB, namely sunburns, wrinkles (photoaging), and skin cancer. The UVA-emitting devices also were not very effective at inducing a tan. And so, the idea of a "safe" UVA tan, so highly promoted by the indoor tanning industry just a few years ago, is now gone. It was not abandoned for scientific reasons, but purely out of the market-driven desire for darker and faster tanning than UVA could induce.
