Then use pure water (I bought Evian). I think Kunlun Mountain or Ipoh will do. Be sure to use edible pure water! Apply the paste to the face 15 minutes. Better paint it thicker. It's ok to apply it to the acne area. Then wash it off with water (be careful not to wait until it is dry. Wash off when the surface is dry. If it is too dry, it will stick to the skin. The acne will be relieved obviously the next day. It will be less red. Only once every other day. If the acne marks are removed, you can cook some Tianqi water. After warming, apply it to your face. Tianqi can promote blood circulation and remove blood stasis. Usually adding some food will also have an effect ~ I hope it will help you! Not to mention other people who pay attention to diet. Ps: Don't drink milk.
