Visit any Japanese drugstore and you will come across an impressive selection of sheet face masks. Sheet masks are a huge skincare trend at the moment, and the quickest and easiest way to achieve an extra boost of hydration and glowiness for your skin at home. Lu Lu Lun is one of the most readily available and popular brands of Japanese sheet masks, with three different formulations available (moisturizing is pink, high moisture is purple, and brightening is white). My favorite is the high moisture mask, which comes in the easily recognisable purple foil pack. This pack contains seven sheet masks, one for each day of the week, for only ¥400!
