This is the big question everyone asks.  What causes skin to turn brown when you are spray tanned?  The secret is DHA.  DHA has been is use since for over 40 years and obtained FDA approval as a skin safe coloring agent.

A DHA based tan looks very similar in color to a standard brown UV based suntan. But you are able to achieve the equivalent color, of many hours of intense UV exposure, in a single product application. The products are called “sunless" because they do not utilize UV or Sun exposure to create the tanned color. Many lighter skin types find they can get much darker with a DHA based sunless tanner, then they can with UV exposure.

With proper product application and appropriate skincare, you will find your sunless tan can easily last 5 to 10 days, and fades similarly to a UV based Suntan. To “tan" again, you simply reapply the tanning product, and within a few hours, you can have a Summer Season tan, - year round.
