If you were to bottle together wasabi and lip balm, this is what you would get. Oh yes, it burns. Does it make your lips plumper? Not sure, I wiped that sh*t off fast. My lips did feel a little more moisturised, maybe. It has a thick consistency. While it does feel like I haven't given this product a proper chance yet, it's questionable whether maybe making your lips swell a little by burning them is really worth it? I'll come back to edit this review if I try it out again, but the trauma of the burning sensation combined with the smell (familiar but not in a good way lol) is making the chances of that relatively slim. This feels more like a novelty product you'd make your friends or family try as a prank.
