How Dark Self Tanners Function

By Haywwod Hunter


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 might occur deliberately or involuntarily. Individuals who do it voluntarily may use chemical commodities or involve in sun bathing. Prolonged unintentional exposure to sun radiation may present a few benefits along some adverse consequences. The benefit is that exposing the skin to ultraviolet radiation, enables it to synthesize Vitamin D. Sun bathing for too long may cause a higher risk of aging, depressed immune system functioning, skin cancer, and sunburn.

Dark self tanners appear in various shapes, colors, and sizes. They are built of metallic materials such as iron, stainless steel, aluminum, or their respective alloys. There shapes are cylindrical to form a cavity within which a person lies down. Dark self tanners also contain leads which have UV sources. Once one lies down, the UV sources are switched on to illuminate the body. The dimensions of tanners are designed to suit that of adult human beings.

Dark self tanners have predetermined intensity settings and time brackets, which one should stay inside. Beyond that bracket of intensity or time, the rays become unsafe for human skins. Tanning differs among people, with others taking shorter periods whereas others take too much time. The ease of tanning of someone is dependent on genetic characteristics like 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 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 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.
