How Spray Tan works

Despite the numerous formulations that exist on the market, the basic colour changing process of spraytanning is based upon DHA in combination with other ingredients designed to alter things like colour and absorption enhancing properties like evenness and depth which can affect how long-lasting the result will hold.

DHA, is not a dye, stain or paint, but an active ingredient which reacts with the amino acids present in the skin. The reaction is very similar to what food chemists refer to as the Mailard Reaction, which is the browning process observed in foods during processing and storage.

Erythrulose, similar to DHA but slower in developing a result, is often used in combination with DHA resulting in a longer lasting effect.

Cosmetic bronzers provide the solutions their darker tint, which also provide the immediate colour effect which neither DHA nor Erythrulose can provide. This tint greatly assists the technician to identify even application, as well as provide clients with an approximate indication of the level of colour they will develop after the completion of the process some 2 – 8 hours later depending on the formulation.

Formulations now include special moisturizers, like Aloe to help keep the skin moisturized, skin tightening ingredients to reduce the appearance of fine lines and wrinkles, as well as a variety of scents to help mask what is generally considered the unpleasant odour associated with sunless products. Unlike just 5-10 years ago however, most products are now pleasantly scented, or even without scent.

The actual long-lasting colour change takes anywhere from 2-8 hours depending on the exact formulation. During this time clients cannot shower, or do any vigorous activity that may result in diluting or removing the product thereby affecting the result.

The long-lasting colour change develops in the outermost layers of the epidermis, which is why the colour generally lasts 4-10 days and not longer. Professional treatments usually contain higher levels of DHA ranging from 5 – 15%, resulting in longer-lasting colour in comparison to at-home selftanning treatments which usually contain concentrations below 5%.
