This is the Busy Babe Golden Nights Express Tan, and the reason I wanted to try it is because it’s an express self tanning mousse that develops in as little as one hour. One hour gives a light glow, two hours gives a medium bronzed look, and three hours gives a deeper darker tan. Since I personally love a deeper tan, I left it on for the full three hour express tan test, rinsed it off, and now the color will continue developing over the next 24 hours. selftanner sunlesstan expresstan beautyover40 beautyfinds
