Sunless tanning is exactly what the name implies. It is any method of achieving a sun kissed appearance without actually absorbing rays from the sun. Different methods include sunless tanning lotions, tanning beds, mists, airbrushing and an assortment of other options. While tanning beds and other such units technically fall into this category, because they don't include exposure to the sun, they should not be considered harmless. Most contain harmful rays that can burn or otherwise damage the skin.
