Sunless Tanning And Products

Sunless Tanning And Products

Sunless tanning, like the​ name suggests, is​ getting a​ tan without sun exposure, and​ still produces an​ effect similar in​ appearance to​ a​ traditional suntan. This method of​ tanning does not involve skin pigmentation or​ UV exposure, which is​ often dangerous, to​ set off the​ change in​ skin color. Sunless tanning is​ also often non-toxic and​ thus, is​ quite safe. However, tan is​ temporary and​ will wear out or​ fade away within a​ couple of​ days.

Sunless tanning products affect the​ Stratum Corneum, the​ surface layer of​ the​ skin or​ the​ outermost layer of​ the​ epidermis, while the​ Stratum Basale, the​ deepest layer, is​ affected by tanning under the​ sun. There is​ a​ wide variety of​ sunless tanning products available on the​ market today, such as​ tanning pills, sunless or​ self-tanners and​ bronzers, available in​ the​ form of​ gels, lotions, mousses, sprays and​ wipes. They can be applied at​ home in​ private, or​ professionally in​ spas, salons, and​ other health centers.

Many sunless tanning and​ cosmetic product manufacturers use an​ active ingredient called dihydroxyacetone (DHA), a​ colorless sugar that interacts with the​ dead cells located in​ the​ stratum corneum of​ the​ epidermis, as​ an​ active ingredient. This is​ because a​ change in​ skin color occurs when dihydroxyacetone creates a​ reaction with amino acids in​ the​ dead layer of​ the​ skin. the​ American Academy of​ Dermatology suggests that sunless tanning products that contain DHA are the​ most effective in​ creating a​ long-lasting tan.

Erythrulose, a​ natural based keto-sugar which reacts with the​ amino acids in​ the​ keratin protein on the​ outer or​ dead surface layer of​ the​ skin, is​ also often combined with DHA to​ create a​ longer lasting sunless tan. However, Erythrulose, like DHA, may cause contact dermatitis, a​ skin irritation characterized by red, flaky skin, sometimes with cracks or​ tiny blisters.

Other types of​ sunless tanning products such as​ tanning creams, lotions or​ pills usually contain the​ amino acid – Tyrosine. it​ is​ believed that Tyrosine aids in​ the​ stimulation and​ regeneration of​ melanin (Melanin is​ a​ pigment and​ the​ primary determinant of​ color in​ human skin). This, if​ true, greatly affects and​ accelerates the​ tanning process so that’s why many sunless tanning products are called tanning accelerators.

Tanning pills also belong to​ the​ category of​ sunless tanning products, and​ often contain the​ chemical – Canthaxanthin. the​ chemical works by depositing and​ spreading itself all over the​ body, including in​ the​ skin after it’s consumed, taking on an​ orange-brown color. Canthaxanthin is​ basically a​ coloring agent used in​ foods so the​ FDA does not approve its use a​ tanning agent. However, many cosmetic companies continue to​ use it​ in​ large quantities as​ an​ active agent in​ tanning products. it​ has also been established that continual use of​ canthaxanthin can cause hepatitis and​ canthaxanthin retinopathy.

One of​ the​ recent additions to​ sunless tanning remedies is​ Melanotan, a​ melanocyte (cells located in​ the​ bottom layer of​ the​ skin's epidermis) - stimulating hormone. Melanotan works by inducing skin pigment. Although extensively tested in​ countries like Australia, it​ has to​ be yet approved for​ clinical trials in​ the​ USA.
