Sunless tanning (also known as self tanning, or UV-free tanning refers to applying chemicals on the skin to produce an effect similar in appearance to a traditional suntan. A more common, although somewhat derisive term is fake tan, canned tan, or fake 'n bake. Sunless tanning arose in response to links between sun exposure and skin cancer discovered in the 1960s, along with other alternatives to natural sun tanning such as the use of a sunbed (also known as a tanning bed).
