How Dark Self Tan Functions

By Haywwod Hunter


Dark self tan occurs in the outermost stratum of the skin known as the epidermis. Epidermis is also made of many other layers, among them is stratum corneum. Stratum corneum is the layer that gets affected by dark self tan equipments and products. The procedure of tanning is fundamentally similar among a wide range of techniques and dark self tan products. This article outlines some fundamentals of self tan commodities.

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 mixed with DHA, they work together to minimize streaking and discoloring, hence generating a natural tan. The tan lasts longer and fades away uniformly resulting in a continuous natural appearance. Most products have a guide color. Guide colors are intended to show someone where on the skin they have applied the dark self tan already and places they have not. They also enhance the cosmetic appearance of skin surfaces although they do not last long since they wash away.

Bronzers produce immediate effect that can be removed easily using soap and water. They are obtainable from beauty shops in powder, lotion, and cream form. They are more of make-ups than dark self tan commodities as they only stay on the skin surface when it is not washed. Most efficient sunless tanners appear in spray and lotion forms with DHA dihydroxyacetone as the primary 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.

Deposits of canthaxanthin are associated with many deadly side effects like hepatitis and canthaxanthin retinopathy. Tanning accelerators are lotions or pills that contain amino acid tyrosine. Producers of these accelerators argue that tyrosine has the ability to trigger and increase melanin formation. The likely side effects of using large quantities of tyrosine and soundness of the assertions that it really darkens the skin need additional 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.
