Any ABT
solution will have slight variances depending on the skin of the client. How well they have exfoliated, how hydrated they are, prior UV tanning damage, can all affect how well their skin "takes" the ABT
solution .
I recommend going to a more sunless tanning oriented board, such as abtan.com or sunless.com and doing a search on "best solutions" to see why people like certain solutions.
In my experience, Tampa Bay Tan is the best, but you should really get samples of as many solutions as you can, and go from there. Best of luck to you!
