Yesterday Dior dropped a little BTS video of Bella Hadid getting made up by Dior artist Peter Phillips, and while there were takeaways that were not so wearable (like, dark chocolate eyeshadow from lash to brow), we did spot a familiar product in Dior's ever popular Lip Maximizer plumping gloss. Bella can't get enough: "It's my favorite stuff. Ever since I got it I haven't taken it out of my bag."

The idea that all it takes for fuller lips is a few swipes of gloss is a little dubious, but people seem to love a good lip plumping product. Noted Hadid [Gigi] called out one in her Top Shelf After Dark; Glossier's Community Manager Kim Johnson swears by it as one of her mainstay lip products (the above tube belongs to her). They supposedly sting when applied, which might lead some to believe that there are active ingredients at work. But are there? Are they actually effective? Please share your experiences below—if only because we all want to look a little more like Hadidlike.
