◇If cream gets on the mouth of the container, wipe it off thoroughly. ◇In rare cases, the moisture in the cream evaporates and the whitening active ingredient crystallizes and adheres to the mouth. It may feel rough when it touches the skin, but this does not affect the quality. ◇After use, close the cap tightly. ◇Do not store in direct sunlight or in high or low temperature locations. ◇The container can be used as is, so after use, remove the container and use the refill (sold separately).
