My lips are quite thin, so I am always looking for ways to plump them up without surgery. Sadly this product did absolutely nothing, I've tested it on multiple occasions. After application, you can feel tingling on your lips, as if you've just eaten spicy food. It has a sweet scent and test and visually it looks like wasabi. Unfortunately, this product serves as a lip gloss rather than plumper, but others might have different experience than me.
