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 achieved by involvement in sun bathing whereas casual unintentional exposure to sun rays may have adverse effects as well as some benefits. Benefits consist of synthesis of vitamin D under the skin. Excessive exposure causes possible skin cancer, sunburns, possible early aging, and depressed immune system function. Sunscreens are made use of to prevent sunburns on parts of skin open to sun tanner equipment or the natural sun. The tanning procedure may also be accelerated by certain oils.
Tanning process differ among people. Some people change skin color quickly and with a lot of ease while others take long. This is caused by differences in types of skin and natural skin color among people. These two aspects are influenced by genetics.
Cells referred to as melanocytes, which are located in the deepest film of the skin secrete melanin. This process is called melanogenesis. Melanocytes create 2 forms of melanin, eumelanin and pheomelanin. Eumelanin is dark brown in color whereas pheomelanin is red. Melanin functions to protect interior body organs through absorption of destructive solar energy. Destructive solar beams cause both indirect and direct damage to strings of DNA. This damage needs to be rectified by the body quickly through secretion of more melanin.
With increased generation of melanin, skin tone becomes darker, though the UV-B component might cause some sunburn effect. The tanning effect is also attainable using artificial UV tanners. A sun tanner delivers either UVB, UVA, or both. Formation of tans by exposure to ultraviolet happens by two different processes. To begin with, UVA beams create oxidative stress that in turn causes oxidation of the already existing melanin. Once oxidized, the color of melanin turns to dark brown.
The radiations produced by a sun tanner also redistributes melanin from its storage location, but its initial amount remains the same. The second procedure is stimulated primarily by UVB radiation. The rate of melanogenesis increases leading to more melanin. This entire reaction starts due to direct photo-damage caused by UV beams. Melanogenesis process delays tanning, which becomes noticeable after seventy two hours after the first exposure. The tan created by increased melanogenesis stays longer than that caused by oxidation reaction. It guards against skin damages in a better way than simple aesthetic function offered by UV-A beams.
The sun tanner used to generate artificial ultraviolet radiation is shaped like a casket. A person lies inside the sun tanner and beams of light are radiated on their body. There is a given period of time that one needs to last inside the sun tanner. Beyond that time, the rays become excessively harmful. The sun tanner has a lead, on which the lights are placed.
A sun tanner is a pricey device depending on the version one needs to obtain. The difference might however not be so significant since they all attain same effects and results. One should always compare costs among producers before purchasing one. A Sun tanner can be made in various designs and sizes.
