◇ If the mouth of the container is covered with cream, wipe it off well. ◇ In rare cases, the moisture in the cream evaporates, and crystals of whitening active ingredients adhere to the mouth. It may feel rough when it touches your skin, but there is no problem with the quality. ◇Do not leave in direct sunlight or in places with high or low temperatures. ◇If the container is damaged or peeled off, we recommend that you replace it with a new main container.
