I%26#039;ve read lost of stuff that says using toothpaste on a pimple will help to get rid of it. That%26#039;s all fine and good. But in all the same places, I%26#039;ve read that you should not use whitening toothpaste. Why is that?

An overnight home remedy for pimples is to put a dab of toothpaste on it to help dry it out or else you can try Calamine lotion it will also have the same drying effect.
