Don't bother trying this product. It advertises that it's like getting a shot of collagen in your lips. I didn't see any real difference. I felt a little tingling and that was it. A better product (and much cheaper!) is Sally Hansen Lip Inflation.
I bought a product called Lip Plump once, and it was useless.
they are all useless, I have tried several.
I share the frustration. I'm probably going down the path of lip augment with juvederm or restylane. Too many $40 lip "plumpers" that didn't do the job
