I tried something called "Air Stockings" once - and only once! Sprayed it on before work in the shower (no, not when it was running) and was then late for work as I had to clean it down - what a mess!
I have one or two age spots on my face, and found when I used my usual Clarins facial tanning cream, the spots looked much worse as the colour seemed to "stick" to them. I plan to try again using Vaseline over the spots as a barrier.
I do use leg make-up made by L'Oreal or Number 7, very nice cover and doesn't matter if you haven't time to exfoliate beforehand. Otherwise I also find one of those body lotions with mild tanning effect take the glare away.
