Tanning beds are often used for cosmetic purposes, especially among adolescents and young adults. They emit ultraviolet rays, called UV rays. When the skin is exposed to these UV rays, melanocyte cells produce melanin, a brown pigment that darkens the skin. This is how the skin attempt to protect itself from further damage. Excessive exposure can lead to problems such as skin and eye cancer, and tanning beds are considered unsafe by organizations such as the U. When skin is exposed to UV rays, enzymes are triggered to repair the damage.

Does tanning in a tanning bed cause less damage than natural sunlight? It doesn't matter whether you get it from the sun or from artificial sources such as sun lamps and tanning beds — ultraviolet UV radiation is linked to skin cancers including basal cell carcinoma, squamous cell carcinoma, and melanoma and to other sorts of skin damage, particularly premature skin aging photoaging. UV radiation is one part of the spectrum of light that reaches the earth from the sun. At the UV end of the spectrum, the wavelengths are too short to be visible to the naked eye. They range in length from to nanometers nm, or billionths of a meter and are classified — from the longest to the shortest — as UVA to nm , UVB to nm , and UVC to nm. UVA rays, which penetrate deep into the skin, are responsible for tanning. UVB rays damage superficial skin cell layers, causing sunburn.
