You can wash it every day. I will wash it every day. After using it for more than half a year, my face was very white.

However, you must wash it with facial cleanser first, and then with milk. Milk has no cleaning effect.

Also, remember to rinse after washing with milk, otherwise the milk will ferment on your face and be harmful to your face. After washing, apply some toner and you can go to bed.

Ha ha! ! Hope useful to you
