Prep Your Body
Shower and shave a few hours before self-tanning, then smooth the skin's surface with an exfoliator so the color goes on evenly. Use a non-oil-based scrub: Anything greasy will leave a residue that can prevent the formula from penetrating, says N.Y.C. tanning guru Anna Stankiewicz. She likes St. Ives Fresh Skin apricot scrub ($5; at drugstores).
