8 Body-Toning Creams That Actually Make You Look Slimmer

The Product: SkinCeuticals Body Tightening Concentrate ($78)

How It Works: This paraben-free concentrate is made up of tripeptide, yeast extract, and hydrolyzed rice protein, which help the skin to feel more firm. It's specifically targeted for hard-to-tone areas like the thighs, butt, knees, upper arms, and abs. In addition to its contouring capabilities, it also has a cooling, slight tingling effect upon application.
