Are you referring to a moisturizer with sunless tanner built in? I have tried Olay Touch of Sun, but I still like the Jergens brand. The drugstore brand typically works just as well, and is at least a couple bucks cheaper than the name brand. If you plan on applying it to your face, look for the formulation that's made just for faces.
I really like these tinted moisturizers, because those sunless tanners have a habit of really drying out your skin.
