Adopt the complete JOODOC Barrier Glow routine in 3 steps for plump, radiant skin. After cleansing and toning your face, apply the lightest ampoule first with gentle tapping, then follow with the other two in order of texture (from the most fluid to the richest). Use them morning and/or evening, focusing on sensitive areas to strengthen your skin barrier, then always finish with your moisturizer – and sunscreen in the morning.
