Although your complexion already holds somewhat of a tan, a too-orange effect can also be apparent if you choose the wrong formula, or if your self-tanner reacts to a product already layered on your skin. "Make sure you used basic products like body wash and scrubs that are mineral-oil free and do not leave residue behind on the skin," says Evans. "Certain products used with a self-tan can interfere with the overall color." Because the St. Tropez Self Tan Luxe Dry Oil ($50) is so hydrating, you can take the minimal route on the lotion and apply only where needed. We also love the natural sun-kissed effect Guerlain's Terracotta Sunless Gel ($52) imparts, not to mention how easy it is to blend.
