my mom always told me to do this and it actually works.
the best kind of toothpaste to use is the kind that is plane white but aqua fresh or anything with different colors still works.
first wet your face then pat it dry so it is still a little damp then put the toothpaste on your pimples not on the whole face. i would reccommend doing this before sleep and leaving it on overnight (or else leave it on for about two hours) then really rinse your face and wash like you would regular.
