Homemade Acne Treatment

I used to have really bad acne. My mom always told me to apply toothpaste to my acne, let dry and wash off but that sometimes drys out my skin. My sister always stirred egg white until it was frothy and put it on her face until it dried, then the same with the egg yolk immediately after. That never worked for me. So I tried several different home remedies and finally found one that's rather cheap and very effective.
