A sun tanner is a device or a product utilized to tan or to darken the skin color. The process is normally as a consequence of exposure to ultraviolet radiation from the sun or artificial sources. Tanning beds are the major artificial sources of ultraviolet radiation used. This effect can also result from reflected light, chemical products, or windburn.
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 differs among people, with some changing skin color fast and more easily than others. This results from differences in skin type and natural skin color. These 2 factors are a matter of 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 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 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.
