I've used the dark for the last year+. I was so excited to try the ultra dark. The ultra dark isn't really a "tan" shade like a tan from the sun. It's more or a pale brown natural skin color (if that makes sense???) Also, I've had to spend a few days exfoliating and getting it COMPLETELY off before re-doing the tan. It DOES NOT come off evenly. I did not have this problem with the dark. The first time I re-did my tan and did not get the tan before completely off and it looked horrible, super splotchy. With the dark I could layer it up and it was always even. I don't like how I have to take a few days going completely back to my very pale skin color before reapplying. It is very noticeable to people when you are super pale one day, and then pale brown the next, vice versa. I will not get the ultra dark again, when I re-order I will go back to the dark, where the color looks much more like a sun tan than a pale brown color.
