I had the natural spray tan just prior to a Caribbean vacation. It was ok -- but not what I expected at all. First, this is a sugar based tinted spray. I think it just stains the skin. Be aware there are a bunch of rules you must follow to maintain the color, like no washing hands for a day, no oil products, no Dove brand etc.... I had to stop on the way home to buy soap. Be sure your nails are already done before this treatment. When I got home I realized I had spent a ton of money on new makeup -- foundation specifically and this tan color was way different than anything close to what I naturally look like -- so I immediately washed it off my face and neck... well that meant I lost the color from the tops of my hands. Probably just as well because I am a big believer in hand washing!
Bottom line .... it worked to warm up my dead winter white arms and legs at least long enough to get me to the islands and into the sun. No idea how long it really lasted.
