A sun tanner is an equipment or a product used to make the skin color darker or tanned. The process is usually as a result of exposure to UV radiation from artificial sources or from the sun. Tanning beds are the main artificial sources of UV radiation utilized. This effect may also result from windburn, reflected light, or chemical products.
Deliberate tanning is attained by regular sun bathing whilst casual unintended exposure to sunbeams may have some benefits as well as undesirable effects. Benefits comprise vitamin D synthesis under the skin surface. Excessive exposure causes possible early aging, sunburns, depressed immune system function, and likely skin cancer. Sunscreens are utilized to avoid sunburn effect on parts of skin surface open to the natural sun or sun tanner equipment. Certain oils may also accelerate the tanning procedure.
Tanning process varies among individuals, with some people changing skin color more easily and fast than others. This is due to differences in natural skin color and skin type. These two factors are a result of genetics.
Cells called melanocytes, which lie in the deepest layer of the skin produce melanin. This process is known as melanogenesis. Melanocytes create two forms of melanin, that is eumelanin and pheomelanin. Eumelanin has a dark brown color while pheomelanin is red. The work of melanin is protecting internal body organs through absorption of solar energy. Solar beams cause indirect or direct damage to DNA, which needs to be corrected by the body system through secretion of melanin.
With increased production of melanin, the color of the skin darkens, even though the UV-B may cause sunburn effect. This tanning effect may also be achieved using artificial ultraviolet sun tanners. The artificial sun tanner equipment delivers UV-A, UV-B, or both. Production of a tan through exposure to UV happens in two different ways. To start with, UV-A rays create oxidative stress that oxidizes the already present melanin in turn. Once oxidized, the melanin turns dark brown in color.
The beams from a sun tanner may also redistribute melanin from its storage place, but its original quantity remains unchanged. The second process is triggered chiefly by UV-B radiation. There is an increase in the rate of melanogenesis leading to increased generation of melanin. This entire reaction results from direct photodamage by radiation. Melanogenesis delays the tanning process and is visible after a period of 72 hours after exposure. The tan produced by increased melanogenesis lasts longer than that due to oxidation. It is more protective against skin damage than UV-A beams which do simple cosmetic function.
The sun tanner applied to produce artificial UV beams is casket-shaped. People lie in the sun tanner and ultraviolet rays are radiated on all over their bodies. There is a specified period that one can last inside the sun tanner. Beyond that period, the radiation becomes extremely destructive. The sun tanner contains a lead, on which sources of radiation are fixed.
A sun tanner is an expensive equipment depending on the make one needs to buy. The difference may not be so pronounced because they all have the same effects and achieve the same results. Always compare prices before making a purchase. A sun tanner could be made into several different designs, shapes, and sizes.
