Sunless Spray Tan
Dihydroxyacetone or DHA is the substance that sunless spray tan products use as a main ingredient; this chemical causes the browning of the skin thanks to an interaction with the amino acids in the dermis. The use of sunless spray tan does not involve pigmentation or ultraviolet exposure for the initiation of the coloring process. The color is the only thing that changes in the skin. Longer effects are achieved if the sunless spray tan combines DHA with another chemical: erythrulose, that prolongs the brownish look. Sunless and safe, this is the advantage of modern tanning systems.
Although sunless spray tan products carry FDA approval and certification, there are people who do not tolerate the chemical ingredients. The most serious health issue related to the application of a sunless spray tan is contact dermatitis triggered by the intolerance of DHA or erythrulose. Experts advise and encourage users to test any cosmetic treatment on a small skin portion before applying it on the entire body. It could take a few hours before the absorption is complete, and in order to be safe from allergies, do not apply the sunless spray tan until twenty four hours after the test.
If the skin remains clear in this time interval, then, it means that you tolerate the sunless spray tan well and that you may use it in safe conditions. Sunless spray tan can be applied either in cosmetic salons and spas or at home. A better tan is normally achieved when you choose the professional application because the equipment used in salons allows for an even, uniform body coverage. Spray tan booths represent the most advanced tanning technology you can find, but if compared with the rest of the methods, it is pretty expensive.
In the case of the air-brusher, the sunless spray tan may not be perfect given the fact that overlapping is possible. Even so, this tanning technique is superior to the self-application of creams and lotions. The tanning agent is atomized in a thin mist on the body, and depending on how deep you want the tan to be, a double application is possible. Before the use of the sunless spray tan, make sure that the skin is clean, exfoliated and dry, but not oily.
