In general, it’s not the best idea. Spray tanning solution is drying to the skin. Spray tanning on top of another airbrush tan will dry out the skin to the point where the new tan will not fully develop well. Especially in climates like Minnesota/Wisconsin with harsh winters and dry skin most of the year. It can cause patchiness, poor fading, and poor coloring. Typically, you want to wait until the first spray tan has faded before getting another one.
