Dark self turners refer to equipment or products used to tan skin or make its color darker. Dark self tanners or the sun produce the ultraviolet radiation that is used to achieve this effect. Windburn or reflected light may also produce the same effect if one is exposed to them for a long time.

Dark self tanning can occur intentionally or unintentionally. People who do it intentionally may engage in sun bathing or they may use chemical products. Unintentional exposure to sunbeams for a long time may present some unfavorable consequences although there are some benefits. The skin when exposed to ultraviolet radiation synthesizes Vitamin D. Excess exposure may cause sunburn, skin cancer, depressed function in the immune system, and a higher danger of aging.

Dark self tanners are produced in various colors, sizes, and shapes. They are built from metallic materials like stainless steel, aluminum, and iron or the respective alloys. They are shaped like cylinders to form a hollow in which a person can lie. Dark self tanners contain leads on which UV sources are fixed. Once one takes position in the cavity, ultraviolet are switched on to radiate the skin. The measurements of dark self tanners are made to suit the size of an adult.

Dark self tanners have set time frames and intensity settings, which one may stay in. Beyond that intensity or time, the radiation becomes unsafe for the skin. Tanning differs among individuals, with others taking a short time while others take very long. The simplicity with which one can tan depends on genetic attributes like natural skin type and color.

There are two key manners in which skin color is affected by dark self tanners. Ultraviolet rays generated by dark self tanners can be categorized into UVA and UVB. Both variants result into melanogenesis, the process by which melanocytes synthesize melanin pigments. Melanin pigments are also of two kinds, the brown one referred to as eumelanin and the red one called pheomelanini.

The job of melanin is to take in solar radiation therefore protecting body organs. Excess solar rays can cause indirect or direct damage to DNA strings. The body counters these damages by generating and emitting more melanin into skin cells. This increased generation of melanin is primarily triggered by UV-B beams due to direct or indirect photodamage. The tan that results due to this activity is darker and stays longer but only becomes noticeable after seventy two hours of exposure.

UV-A also results in creation of a tan. Here, UV-A causes oxidative stress, which leads to oxidation of the melanin already present. When melanin is oxidized, its color turns to dark brown. UVA generated by the sun or dark self tanners also causes existing melanin to redistribute although its quantity remains the same. This makes oxidation of melanin less capable of protecting the body against UV damage than UVB. Dark self tanners have a lot of uses in the fashion businesses, where models utilize them to darken their skins before engaging in competitions.

Dark self tanners are pricey appliances. They require proper maintenance and handling so that they can last long. If proper care is accorded to dark self tanners, they might last for many years.
