What it is: E.L.F. Cosmetics Prismatic Glowtion ($8)
Why you need it: A good, full-body highlight transcends seasons, but Spring calls for a lighter formula. Ditch your heavy powder luminizer for this creamy drugstore option. Along with prepping your skin for makeup, this sugar-cane- and vitamin-E-infused primer leaves a subtle shine that glows from beneath your foundation. Since it's a liquid, there's nothing stopping you from rubbing this shiny stuff over your collarbone, legs, or anywhere else you want to totally radiate.
