How to make skin white and healthy

I have a small folk prescription: after cleansing, melt the white sugar and apply it evenly on your face./kloc-Wash it after 0/5 minutes. Twice a week. Stick to 1 month, and you will find that your face is white and tender. As a poor student, I usually do this. This is my personal experience. I think it is economical, convenient and effective.
