I have mixed opinions about this lip plumper. I went to sephora and asked what the best lip plumper in the whole store was and the employee pointed me to this product. I wanted to try it because it was under $30. I chose the clear color (matte) formula. I really liked the packaging- it’s slick and hip on one hand, yet on the other hand it’s kind of almost a chore to just open- you have to twist the top til it pops up and then pull the wand from the bottle. But that’s what makes it cool, too. It’s definitely different, though. I was also confused about the actual wand- I haven’t seen that specific type of application too before so it kind of threw me off a bit at first. I couldn’t understand how to apply the plumper using the strange (well, strange TO ME) tip applicator. Once applied, the plumper starts its usual tingling sensation and to me, it’s bearable. It’s definitely not a painful sensation at all which is nice. But as far as performance goes, well I can’t say exactly if it really, truly plumped my lips. This formula is matte so it’s not too shiny or sticky. It lasts on lips as long as any other lip gloss and rubs off after eating or drinking. I can’t say exactly if it plumped my lips to where they were noticeably bigger but it definitely tingled my lips to a semi-irritated red color and a kind-of-enflamed shape. I want to be honest and note that I’m prone to hereditary cold sores and although I don’t get them as often as I used to when I was young, they can still be triggered by different things like wind/cold weather, too much sun or burned in a tanning bed, as well as immune system weakness and other irritations. So when I applied this plumper for the VERY FIRST TIME, my lips burned and were irritated from the tingle sensation and must have gotten so stressed out that the very next day I woke up with a cold sore. Now, I don’t know if the plumper is what CAUSED it, but I wanted to note it anyways. This only happened that one time, and I have used my plumper a few times since with no problems to note. But that’s the thing- I have only used it few more times since I have purchased this product. So over all I think it’s good for the price but I feel like I need to test this more to have a more confident review, so for now I would say it’s ok!
