I want to caveat here that I do dabble in lip filler from time to time, but I still rely on a plumping lip gloss in my day-to-day. For those times in-between appointments or when I want to take things up a notch even more, a volume-boosting formula is a maintain in my everyday make-up routine. And if you don't fancy fillers but want to see a temporary plumpness, a plumping lip gloss is unbeatable.
There's much speculation over whether lip plumpers actually work, but in my experience when you find a good one, they make all the difference. So, how do they work? Most rely on the product (and its ingredients) to cause a very mild irritation to lips, which in turn increases blood flow to the area. Thus, lips appear plumper, usually for a matter of hours at a time.
