If you don’t have time to hit the gym but want legs as amazing as Jennifer Lopez‘s, try skin-highlighting makeup. “Legs look leaner and more toned when they have a bit of a glow,” says N.Y.C. makeup artist Linda Hay, who suggests exfoliating weekly for a smooth base. A gradual tanner can add a hint of color over time, but if you want instant results, go with bronzing lotion like Scott Barnes’s Body Bling (pictured, $38 at scottbarnes.com). Apply in a circular motion to prevent streaking. To create the illusion of slimmer legs, dab a touch of highlighter down the center of each leg, blending well to ensure a natural effect.
