Right, I have purchased many many lip plumpers and none have even slightly worked on me!I was lucky enough to receive this lip plumper in an advent calendar. I was very sceptical as I've said, nothing has worked previously. I had the clear gloss.I applied it and OMG, I could see results in seconds!!! It leaves a tingle on your lips but it's totally bearable and isn't painful. It was a clead gloss yet as it started to work it gave mg lips a lovely dark pink / rosey pink colour to my lips, I'm assuming it's because it's drawing the blood to the surface?It lasted a long while too, I applied a lip crayon over the top to add slight colour.Honestly if like me and lip plumpers have failed you, give this ago!! I will be buying many many in future.
