With the mother of all jet lag the SHISEIDO BENEFIANCE WRINKLE RESIST 24 PURE RETINOL EXPRESS SOOTHING EYE MASK is what I reach for before I go anywhere near a concealer. They are great for on the plane or if you have had a few too many late nights / early mornings I sometimes put one on in the taxi on the way to a job (giving many an Addison Lee or Uber driver a fright).
Great alternatives include ELEMIS PRO-COLLAGEN HYDRA GEL EYE MASKS and for the younger ladies EYEKO HYDROGEL EYE PATCH.
