A sun tanner refers to a product or a device utilized to darken or to tan the skin color. This process is because of exposure to UV beams from the sun and/or artificial sources. The major artificial devices used to produce ultraviolet radiation are tanning beds. This effect could also result from chemical products, windburn, or reflected light.
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 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 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 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 radiation form the sun tanner also redistributes melanin from its place of storage, but its original amount remains constant. The second procedure is triggered primarily by UV-B beams. There is an increased rate of melanogenesis resulting in more melanin. This whole reaction is due to direct photodamage by UV radiation. Melanogenesis holds up the tanning process, which becomes visible after 72 hours after the initial exposure. The tan generated by increased rate of melanogenesis is more durable than that due to oxidation reaction. It protects against skin damages more than simple cosmetic function like in 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 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.
