Nyx Pump It Up is one of many lip plumping glosses on the market. At a reasonable £6.50 via Boots.com, it works by tingling the lips making them swell a little & look bigger. It's not as painful as I've just made it sound, I promise, in fact I quite like the feeling!
From the nine colours I chose the neutral, translucent gloss 'Liv' so I can wear it over my usual lipsticks.
The product definitely works, you can see the difference in my before & after pics, so I would give it the thumbs up and recommend it. A short review, but there we go!
