Apply the LUVUM Bamboo Hyaluronic Acid serum on clean skin, right after toner. Dispense 2 to 3 pumps into the palm of your hand, then gently pat onto the face and neck to enhance absorption. Use it morning and evening before your moisturizer to boost hydration and strengthen the skin barrier. The 50ml+50ml set provides a continuous moisturizing routine, ideal for dehydrated or dull skin.
