I have tested a lot of different lip plumpers, as Sister Mia often bought it before.
A lip plumper is a lip gloss that contains various substances that get lips to swell which gives a fuller effect. It can be chemical substances that bind water or natural substances such as chili peppers and ginger mint.
However, it has never worked on my lips, I think you are a little differently sensitive to it. You can, for example, check this old post and you will see an example.
A tip is to test before you buy!
In addition sticks lip plumpers often in the lips, and the from gloMinerals which I tested today almost hurts!
But my God so nice color! The shade is called Very Cherry.
Definitely worth the unpleasant feeling, just for the shine itself :)
Lip plumper immediately after application.
After approx. 5 minutes.
