UsageAfter having prepared skin with a lotion, I pick up an appropriate amount, and it is easy for the whole face little by little carefully, and, please stretch it out.When symptoms such as a rash, a reddish tinge, the swelling come out, I cancel use and recommend the consultation to dermatologists. Please keep it out of reach of infants. I avoid direct rays of the sun, and, please keep it in a cool and dark space.
