self tanning

thanks guys, I have been using the lotions for a few years now. (different brands). but... my daughter says after a while I start looking yellow. I thought I would gets some reviews on her on the different brands.

how long does the spray on tan last? and what is the cost?

I used to use the tanning beds when I had my own salon. (years ago) that was great because I also used that time to fully relax. wrinkles seem to be a problem after a while with those and the "real sun", so I decided I would be better off in the long run if I switched to the lotions.
