Times have changed and pouty duck-lips have become beyond passé. However, there is a natural way to plumpen your pout with an at-home / diy procedure. The two required materials are a toothbrush (preferably straight bristled) and petroleum jelly.

Step by step:
Apply some petroleum jelly to the toothbrush
Rub the toothbrush onto your lips in a circular motion
(be cautious not to rub too hard, you don’t want to tear your skin)
Leave some of the petroleum jelly on your lips once your finished rubbing in order to rehydrate

One of the pros to exfoliating your lips is a temporary plumper complexion. The action of massaging your lip tissue promotes the flow of blood and creates a more ample and pillowy appearance.

Another pro is that it gets rid of dead skin — exfoliating renews your skin by promoting generation of new skin (due to the scrapping of the old, dead skin).

Additionally, exfoliating will also get rid of makeup residue.
Any excess lip-stain will be discarded along with dead skin.
