BTW, I find strange that fat loss gels using Forskolin or Forskolin and xanthines combination don't show tanning effects. They use similar formulation as used in patents and the forskolin tanning solution used on mice. And they have to get through skin to fatty tissues. One of them would likely be a good tanner, since it's been proven to realy reduce fat (and it uses 2 cAMP stimulator). Here is its formulation:
Aqua, Ethyl alcohol cosmetic grade, Propylene glycol, Coleus forskohlii extract, Camellia sinensis extract, Methylal, Theophyllinum, Glycerin, Carbomer, Triethanolamine, Phenoxyethanol and mixt Paraben
Menthol, Imidazolidine urea
