This is nice but not worth the cost.

I got this a couple days ago and I’ve been using it numerous times a day. It does not stay long, but it does leave a nice shine. I am not impressed with the level of hydration because I feel like my lips are more dry after using it than before. I can feel the plumping, but it’s not a real noticeable effect at least on me. My lips too appear to be smoother. And it stays on, but not real well.

Useless. TOTALLY USELESS.

Worthless product. Accidently bought it meaning to get an eye primer, but, this stuff is USELESS. It reminds me of the cheapest lip goop made for teens, but, it isn't even scented or glossy. It plumps up nothing but it DOES burn. It's not even useful as a PRIMER. It's thick and lasts 5 mins. USUALLY, PTR products are EXCELLENT but this is a COMPLETE waste of $.

Seriously??? Nope

I have used a different lip plumper for years but after trying the Firmx thought maybe I should try switching and give this a shot. The video completely turned me off from wanting to try this product. Why would any of these women with lip filler or naturally full lips need this product??? How is it showing how well the product works by showing women with already above average full lips??? Show it working on someone with thin or deflated by aging lips then I’ll try it out.

Feels nice

I bought this a month ago and wanted to give it a chance before I made my review. The lip filler feels very nice, tingles a little, but didn't plump my thin lips. I'm still happy I bought it .

Great feel

I really wanted to give this 5 stars but I don’t feel it gave me anything close to lip filler results, I do like how it makes my lips feel but deft not lip filler type

Not the best

I I use a lot of Peter thomas Roth products never been disappointed in anything other than this one it was not effective at all for what it was advertised for. Maybe it’s just me, but this product wasn’t a good product for me.
