Well, despite the feeling that your lips are being burned off your face, the Too Faced Lip Injection, did seem to plump up my lips. I only had it on for about 10 minutes. But they appeared as if they were swelling. And they were
red!
I haven't tried any other lip plumper though, unless you want to count the Buxom Lips lip gloss. Buxom claims to plump lips up, but I never saw much of a difference. It has a slight tingle, which I always liked. My lips appeared less wrinkled when I wore it, but not "plumped". Lip injection looked (and felt) like I was stung by forty bees.
If you
really want plumped lips, give Lip Injection a try. It's not an important issue with me. I'm sticking with my Buxom Lips
