I've been on the lookout for a good lip plumper for a while now, and a few weeks ago found Dirty Works' lip plumper and decided to give it a try. It has a delicious chocolate flavor which i absolutely love, I mean who doesn't like chocolate, right? anyways. The first few times i used it it burned my lips a bit, but it was nothing too hectic, and after the 4th application it didn't even tingle. After about 3 minutes I can see the difference in my lip size, especially the bottom lip. It doesn't make a huge difference but it definitely works, and it even moisturizes as well! Just reapply every hour. I never leave the house without it!
