How Dark Self Tan Works

Dark self tan takes place in the outermost layer of the skin referred to as the epidermis. The epidermis is also composed of several other layers, among them being stratum corneum. The stratum corneum is the one that is affected by dark self tan products and equipments. The process of tanning is basically the same among a wide variety of dark self tan products and techniques. This article highlights some basics of self tan products.



DHA is the short form for Dihydroxyacetone. This substance has been in use in tanning skin since 1970s. It was however until late 1980s that the cosmetic industry found a way of producing superior results with it. The browner but less orange results attained using this product are attributed to the improved refining procedure which yields higher and more predictable qualities.



Another common dark self tan is Erythrulose. This dark self tan commodity functions in the same way as DHA. These two dark self tan products undergo a reaction with the amino acids within the outermost skin layers to turn the color of the skin to brownish. Erythrulose is a type of Ketose, which reacts with amino acids in their keratin form. These reaction results in formation of melanoids, some brownish polymers. In case Erythulose is used singly, it may be applied daily and it does not result in dark tan.



When Erythulose is blended with DHA, they function together to minimize discoloring and streaking, hence producing a naturally looking tan. The tan also lasts longer and it fades away uniformly for a continuous natural look. Most products contain a guide color. The guide color is intended to show one where they have already applied the dark self tan and where they have not. It also enhances the cosmetic appearance of the skin although it does not last long since it washes away.



Bronzers generate instantaneous effect that is easily removable with water and soap. Bronzers are available in cosmetic stores in form of lotions, creams, and powders. Bronzers are more of a make-up than dark self tan products since they only last as long as the skin is not washed. Most effective sunless tanning products are in form of lotions and sprays with dihydroxyacetone as the main active component.



Dark self tan pills contain canthaxanthin as the most dominant and most active pigment. Most standardizing bodies have not authorized its use as a tanning agent even though it is used as a color additive in various foods. Canthaxanthin must be consumed in huge quantities if it has to have any effect on skin color. This pigment is deposited on many organs including the skin, liver, brain, and heart among others.



Deposit of canthaxanthin is associated with many serious side effects like canthaxanthin retinopathy and hepatitis. Tanning accelerators refer to pills or lotions that have amino acid tyrosine. Manufacturers of these accelerators believe that tyrosine has the capability of stimulating and increasing formation of melanin. The possible effects of using large amounts of tyrosine and validity of the claims that it darkens skin color need further scientific proof.



Dark self tan and related tanning procedures form a significant industry in the modern world. It is mostly utilized by models during competitions. Ordinary people may also use it to enhance their appearance.
