I use Jergins. I do recomend you exfoliate your legs a thoroughly beforehand. I shave my legs right before hand, but not my pubic area. Otherwise, the follicles on my legs turn a slightly deeper color.

and yeah, if you use Jergins and only apply it every other day, it will still give you some color. I forgot to apply it to the backs of my knees the first time and you could see the difference.
