These days, with more variety on the beauty market than ever, essential products like lipstick truly have to stand out. Miley Cyrus knows this firsthand from her latest go-to lippie, Maybelline's Moisturizing Serum Lipstick, which she told InStyle is "changing her life." With an innovative serum formula that blends beauty and skincare together, it's easy to see why. Cyrus's drugstore beauty pick - which happens to be on sale now for just $8 - is breaking new ground in the star's beauty routine.
