Using this Laneige cushion foundation is super easy. First, gently press the puff onto the cushion to pick up the product. Then, apply it evenly to your face in a gentle, circular motion. For best results, start from the center of your face and work your way out. Make sure to clean the puff regularly with a mild cleanser to keep it hygienic. When not in use, store the cushion in a cool, dry place. Avoid exposing it to direct sunlight or extreme temperatures, as this can affect the quality of the product. And always remember to check the expiration date before using.
