I first learned about this trick back when I was in High School and I have been doing daily it ever since and I have never had chapped lips. If you wear our lip stains then this is a MUST DO before application, or if you simply want nice chap-free lips! I actually do it right after brushing my teeth in the shower so my skin is already soft and moist from the warm/hot water. Just make sure all of the toothpaste is rinsed from the brush, a few scrubbies and you're good to go! No need to spend money on expensive lip exfoliators!

4. Make flaky lips smooth by applying a balm over your lips, and then exfoliating away any dead skin with a toothbrush.
