Before using lip balm and petroleum jelly, you can actually use your toothbrush, gently scrub your lips with it. It'll remove all the dead skins that's on your lips.

Believe me, after you do it, your lips will feel softer and not so chapped.

There's another way to do it. Homemade recipe. Using Sugar and Honey helps too~ *winks* Just blend sugar and honey together, and use that as a natural scrub.

Good luck~
