Dark self turners are devices or products used for tanning skin or making its color darker. Dark self tanners or natural sun produce ultraviolet radiation used to attain this effect. Reflected light or windburn may also generate the same effect in case one gets exposed to them for too long.
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 predetermined intensity settings and time frames, which one can stay inside. Beyond that time or intensity, the radiation becomes harmful to the skin. Tanning varies among individuals, with some taking a short period while others take too long. The ease with which one tans depends on genetic factors such as natural skin color and type.
There are two major manners in which dark self tanners affect skin color. Ultraviolet beams generated by dark self tanners are categorized into UV-B or UV-A. Both variants lead to melanogenesis, the process through which melanocytes form melanin pigments. Melanin are of 2 kinds, the red one referred to as pheomelanini and the brown one known as eumelanin.
The task of melanin is to soak up solar energy therefore safeguarding the body from damage. Excess solar energy can damage DNA chains directly or indirectly. The body system counters the damage by generating and discharging more melanin into membrane cells. This increased production of melanin is mainly stimulated by UVB beams because of direct or indirect photo-damage. The tan that comes from this activity stays longer and is darker but only becomes evident after three days of exposure.
UV-A also leads to formation of a tan. In this process, UV-A leads to oxidative stress, which causes oxidation of the existing melanin. When the existing melanin is oxidized, its color changes to dark brown. UV-A produced by dark self tanners or the sun also causes the melanin to redistribute but its quantity remains unchanged. This makes the oxidation of melanin less protective against UV damage than UV-B. Dark self tanners find a lot of application in the fashion industry, where models use them to make their skins dark before going for 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.
