How to get rid of undereye circles?
Those annoying blue shadows are caused by dilated blood vessels beneath thin undereye skin. While creams with skin-plumping vitamins C and K can reduce the circles' appearance in four to five months, the best quick fix is a light-reflecting cover-up. We like the Dior Skinflash Radiance Booster Pen ($36; sephora.com). Choose a shade lighter than your natural skin tone and dab it under your eyes.
