The Functioning Of Dark Self Tanners
by Haywwod Hunter
Dark self turners are appliances or products utilized for making skin color darker or for tanning it. Dark self tanners and/or natural sun generate ultraviolet radiation used for attaining this effect. Light reflected from various surfaces or windburn may also cause the same effect over a long period of exposure.
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 come in various sizes, shapes, and colors. They are made of metals such as aluminum, iron, stainless steel, or their alloys. They are cylindrical in shape to form a cavity inside which a person lies. Dark self tanners also have leads which comprise UV sources. Once a person lies inside, the UV sources are turned on to illuminate their body. The sizes of dark self tanners are meant to fit that of an adult human being.
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 ways in which dark self tanners affect the skin color. The ultraviolet beams produced by tanners are classified into UV-A or UV-B. Both variants of UV lead to melanogenesis, which is the process by which melanocytes produce melanin pigment. Melanin are of two types, the red one called pheomelanini and the dark brown one called 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.
UVA also results in generation of a tan. Here, UVA causes oxidative stress that leads to oxidation of melanin that already exists. When melanin gets oxidized, it changes color to dark brown. UVA emitted by the natural sun or self tanners also redistributes the existing melanin even though its quantity does not change. This makes oxidized melanin less competent in protecting the body from ultraviolet destruction than UVB. Dark self tanners have many uses in fashion industry. Models apply them to tan their skins prior to engaging in beauty contests.
Dark self tanners are costly equipment. They need proper handling and care for them to stay long. If good care is given to dark self tanners, they can stay for several years.
