Adopt the Ceramide Boosting Mask as your SOS hydration ritual after your evening cleansing. On clean, dry skin, apply the mask smoothing it well to remove air bubbles, then leave on for 10 to 20 minutes to let the ceramides strengthen your skin barrier, achieving the Korean glass skin effect. Remove it, gently pat the excess until absorbed without rinsing, then follow with your night cream to lock in hydration. Ideal 2 to 3 times a week, or as a treatment before an event for plump, soothed skin.
