Nothing can make us happier throughout the year than having a sun-kissed tan. Solariums, also known as sun beds or tanning booths, are a good way to achieve an amazing tan in a short time. Solarium tanning involves lying in an enclosure which surrounds you with ultraviolet light. It is the UV light that causes the skin to tan. Some experts recommend exposure to a certain amount of UV for therapeutic purposes and for skin conditions such as acne, for example. A solarium is a device emitting ultraviolet rays used to produce a cosmetic tan. They emit a UV ray that is somewhat similar to sunlight. The user lies down on a UV bed, or stands in front of a panel over their skin.
