Hello, dear friend, how are you? Did you touch water after using the product? Use sunscreen to protect your skin during the day Then when using the product, do not touch water for at least 2 hours after using it at night, so that the product can be better absorbed and remove the darkness. This product is very mild. The product quality is guaranteed and tested, dear. Everyone’s skin is different, the degree of darkness is different, and the use time is also different, dear Please keep using it and you will definitely get the skin you want, dear
