I know that there's lots of lip plumpers out there. I'd tried Lip Venom but didn't get great results(just nasty burning) so I thought they were all worthless. So when I tried this one, was I in for a surprise! This stuff stings(not as much as LV) but when I saw the results yeow! My puffed up, turned pink, and looked incredible! The only downside was that the effects last about an hour. A simple reapplication gets the process going again though. In the end it does deliver so that's why I'd buy it again.
