Do sunless tanners really work?

I am extremely pale, and used to be proud of it. Now I'm thinking a little color may be a good idea, but I won't tan outside or in a bed. I burn very easily (10 min. in the sun is all it takes), Melanoma runs in my family, and I've already had sun poisoning from 2nd degree sunburns which increased my susceptibility. I also can't afford spray tanning.
