We all know that lip plumpers wear off quickly and few of them work at all. I say not all of them, DuWop Lip Venom is by far the best bang for your buck. It works the longest and you can actually feel the tingle as it works. Does it last forever, no! None of them do because this is not an injection afterall but if you want a subtle but plumper look for a bit this is the best one. Lip Venom is a transparent gloss that enhances the natural color and shape of the lips by increasing circulation with a spicy, tingly blend of essential oils including cinnamon and ginger. The result: An attractively pumped up pout. You can buy this at several places but I got mine at Sephora.com for $16. Enjoy!
