StilaStila Lush Lips Water Plumping Primer

BUY at Birchbox

Part primer, part lip-plumping balm, this product is 100% awesome. The formula delivers heaps of antiaging peptides, vitamins, and hydration to lips, sealing in moisture and creating the illusion of major volume. Meanwhile, subtle pigments work to even out discoloration, providing the perfect canvas for your lip color of choice. We love using it with matte lipsticks because it prevents caking and dryness while making color last all day.
