Spray Tanning the airbrush tanning revolution What is airbrush tanning? Airbrush tanning is the best way to apply the active ingredient DHA (found in most self tanning products). The fine mist from the airbrush ensures a perfectly even application to the skins surface and as there is no 'rubbing in' required you avoid streaking and patchiness. How long does it take to apply? It takes about 10 to 15 minutes to apply and 10 to 15 minutes to dry. How often can I get an airbrush tan? As often as you like - the solution is completely safe and DHA is approved for cosmetic use. Most people like to top up their tan once a week and it is completely safe to do so. How does the tanning solution work? The tanning solution is made up of TWO tanning agents. 1: an instant bronzer which gives an instant tan effect and allow you to see instant colour and application. 2: DHA - this ingredient gives the most natural looking colour but it takes up to 24 hours to develop. What is DHA (Dihydroxyacetone)? DHA is a colourlesss derivative of sugar cane that has been FDA approved for more than 30 years. DHA darkens the skin by interacting with the amino acids in the dead surface cells found in the outermost layer of the skin, causing it to darken naturally.
