This is a cost-effective refill. Please be sure to refill into the AYAKA Bright Empowering Amulet Serum container. 1. Thoroughly wash the AYAKA Bright Empowering Amulet Serum (30mL) container and the inside of the pump and cap with warm water (avoid boiling water) and dry thoroughly. 2. Cut off the tip of the spout along the dotted line. (Please note that holding the pouch too tightly may cause the contents to spill out.) 3. Bend the spout along the line to make it thinner, then insert it into the mouth of the container and slowly pour the contents in. 4. After refilling, record the manufacturing code on the bottom or cut it off and keep it. You may need it when making inquiries about the product. Please be careful if you have a history of allergies to the ingredients. *The active ingredient, L-ascorbic acid 2-glucoside, may cause the contents to discolor, but this does not affect the quality. <Caution> - Never wash the container, pump, or cap with boiling water as it may cause deformation. Residual moisture may cause the contents to deteriorate, so be sure to dry thoroughly after washing. Also, drying with a hair dryer may cause deformation. After opening, refill the entire contents at once. When opening or refilling, be careful not to cut your hands on the spout or the edge of the bag. Do not store in direct sunlight or in a place with high or low temperatures. If the contents are difficult to dispense after refilling, press the pump several times. If the product becomes dirty or the pump does not work well, purchase a new unit. Use with care, paying close attention to any abnormalities on your skin. Discontinue use if it does not suit your skin. Not a food or drink
