Do Lipstick Plumpers Work?

Answer: Yes, I was really skeptical at first as well. And while the new lipsticks that promise to 'plump your lips' really do work, the effect is temporary. Here's how it works: Some formulas use a traditional lip-plumping ingredient, such as MaxiLip, which stimulates collagen & boost hydration. Others use ingredients that help lips retain moisture, which gives lips the appearance of being fuller.
