Self-tanning products have been around in some form or other since the invention of cosmetics. In 1960, Coppertone introduced its first sunless tanning product - QT® or Quick Tanning Lotion.
This cream produced an overall orange effect. Today's sunless tanning products produce much more realistic results. Sunless-tanning or self-tanning lotions and sprays, tanning pills, and cosmetic bronzers are available to impart a subtle bronze glow or a deep, dark tan. Bronzers give immediate results, although some sunless tanning products require 45 minutes to an hour before taking effect. Though sunless tanning products can yield a golden glow, they do not protect the skin from the ultraviolet radiation in the sun's rays the way melanin in a 'real' tan does, so users of sunless tanning products need to apply sunscreen before venturing out in the sun. Outside Tanning * Bronzers
Cosmetic bronzers produce immediate effects that can be easily removed with soap and water. They are available as powders, creams, and lotions. All these products are essentially a form of make-up, since the tint only lasts until it is washed off. * Tanning Lotions and Sprays
Perhaps the most effective sunless tanning products are lotions and sprays containing dihydroxyacetone (DHA) as the active ingredient. DHA is a neutral sugar that interacts with the dead cells located in the upper layer of the epidermis. Because the sugar interacts with the dead skin cells, a color change occurs. Such achange usually lasts about five to seven days from the initial application.
