Perhaps the most effective sunless tanning products I've heard about are lotions and sprays containing dihydroxyacetone (DHA) as the acting ingredient.

Apparently the sugar interacts with the dead skin cells, a color substitution occurs. This change usually lasts about five to seven days from the initial application.

I'm just wondering if anyone can point me in the right direction as to the best and cheapest option that's known to work. I really don't need to end up all Orange.
