Good luck! I have tried a few (not on my face, but on my legs). Jergens has too much of a smell for me that I won't try them again. ST Tropez seems to be a good one. Mine came with a mit to help even it out more. I currently have a bronzing oil sunscreen from Australian Gold that worked ok. I also have these sunless tanning drops that you mix with lotion. Those were ok, but I did seem to get more streaks than I would have liked. Since you are talking about your face, maybe a bronzing powder?
Whatever you chose, don't go cheap! The cheap ones seem to be the ones that don't work as well. Invest in a good one and let us know your thoughts!
