I tried a Tan Towel from Sephora's Sun Safety kit.. It made me a few shades darker, and lasted a week or two. I forget when I applied it, but I've been out in the sun more often (tsk tsk) so I'm a little less pale than I was before I tried the towel. I also got St. Tropez's self-tanner which has great reviews, but I haven't used it yet.
