I have tried City Lips (OK), Lip Venom (OK), Lip Fusion (Nice gloss, no plumping for me), Sally Hansen "Lip Inflation" (Pathetic), Too Faced "Lip Injection" (Below average), Cinnamon Oil mixed with generic lip gloss (messy), something from Rimmell (Pathetic) and MAC's Plushglass (Nice gloss, no plumping for me), Lorac "Lotsa Lip"(Nice gloss, no plumping for me) .
Then I came to the realization that I just dislike my lips, and tried Restylene about six weeks ago, as well as continuing to use Lip Fusion (because I like it as a gloss anyway).
The Restylene is not lasting very well, and the first injection of the product left me with a lumpy, lopsided lower lip - primarily due to my lips doing strange things when I smile. I had a bit more product placed much deeper into the lip cavity, and one the swelling subsided, it looked OK, but no Angelina Jolie.
I wish that I could tell you that any of the products I have used actually "plumped" my lips, but they didn't really. I have just discovered this forum, and will be trying Dermaglow Instant Lip Plumper next.
I think that the idea of using the "cool wax stuff from benefit" is great, and I think that I may try that too.
In summary, all of the plumping products that I have used and liked worked because I used them A LOT, and their formulations improved the condition of my lips (Kept them moist), and this resulted in a fuller look because my lips weren't tight,chapped and dry.
One product that I didn't like, but I think deserves an honorable mention is "Lip Venom". It did make my lips a little bit fuller, but it bled up the vertical lines and made my lips look like they were in need of a "Tucks" pad. Not a good look.
For anyone who has a Costco membership, they have a great deal on twin-packs of Lip Fusion.
Thanks for all of your posts. I hope that this was helpful.
