As I've gotten older, my lips aren't quite as full as they used to be, & they have some fine lines around the edges. I really don't want to go the route of lip injections, so I wanted to try something less drastic (& less expensive) first. This stuff had the best reviews, so I went with it.
I did not experience any burning, just some tingling. The first couple of times, the tingling was intense, but not painful. Now it's just mild tingling (I guess my lips have gotten used to it). The product has a minty smell/taste, also. It definitely reduces the fine lines in my lips, but not to the degree that I think this stuff is worth the price tag! I like it OK, & if it was $20 or $25 a tube, I might repurchase, but at $50 a tube with limited results for a just a couple of hours (at the most), I just can't bring myself to buy this again when this runs out. continued >>

All in all a great lip conditioner- which I dont thik is what it is meant to be but my lips get so dry no matter what type of balm I use. This is by far the best at keeping them supple and juicy looking.
They do plump up but not like you have just had lip injections. They give you a more fuller look. Which is what I was hoping for.
All in all a great little plumper, without the painful burning tingling that many seem to have. Whilst it does have a slight tingling- its worth it.

I made a review of this item and timed demo on youtube in case anyone is interested: http://www.youtube.com/watch?v=1_q34piivms

On a scale of 1-10:

As a gloss -10
Combined score of 9.2 ! (i think..lol)
Overall this is my HG for lip plumpers. There are other plumpers out there that work, yes, (ahem,toofacedlipinjectionextreme*cough*) HOWEVER, I find that if your wanting to use as a gloss over your lipstick or plain lips for when you go out, you sacrifice in that the taste is horrible, the formula is thick and sticky, or it works so well that it makes the edges of your lips become inflamed and makes you look like you just rubbed a habanero pepper all over your mouth. Not what we exactly want, right?
The price is exorbitant, yes, but I must admit I have 2 of these now. One is in my skincare case that has 2 ends with the original micro-injected collagen gloss and the 2x injected on the other end that I use at nighttime and in my M/U case I have the full size gloss of the 2x micro-injected collagen HA whatever..YA. Forget the flowery name, it works!!!
I don't care about them saying the 2x is for nighttime use, it works better IMHO for use as a top coat gloss than the other original one that has a more milky color to it.
Obviously the price hasn't really deterred me yet...because I keep buying these suckers and am about to purchase another because I'm almost out and I don't want to go a day without having this! :P

I've been using this for a month and really pleased with it. I suffer from very dry lips and neutrogena lip balm has helped. But this product is amazing! I don't need to use that balm every 2 hours anymore. I use this product at night before I sleep and my lips are comfy throughout the day. Yes there's a lovely addictive tingly feeling…I like it so much…weird lol. And it DOES plump up my lips, define them and reduce lines. Makes them look fat. The first night I used it, awoke and went to the kitchen in the morning for coffee. DH was already there. He stared at me: what happened to your lips? Me: why? DH: they look fat and gorgeous.
I didn't expect so much from this product. It was recommended by our MUAers on makeup board so I read the good reviews and decided to spend the $. It's really worth every cent.

I am just nearing the end of my first tube of this stuff, and it has so far lasted me 10 months and I have used it every night. Therefore I dont feel so bad about the price when I know the product lasts for almost a whole year! However, I do not find that it is a great plumper, I have had better results with Bare Minerals Buxom glosses for that. But I do love that it moisturises my lips so well! I used to suffer from dry lips and constantly had to put balms and glosses on. Now after using this stuff every night my lips feel smooth and soft in the day without the need to put anything on them! I will continue to repurchase this item! :)

I first tried this product many years ago when I was 14 and loved it. This stuff doesn't give you super huge lips, but it does plump and make them look smooth and kissable and feel absolutely soft. The price is high and I wish it were cheaper, but it's kind of worth it. The stuff tingles and stings but after a few uses you get used to it and it goes away. It has a nice fruity smell, and it really glosses your lips up. It's the best lip gloss I've ever tried.

My absolute must have product! I have tried every lip plumper under the sun you name it (Duwop LipVenom, Urban Decay Blow, Too Faced Lip Injection and the Too faced Lip night treatment, Sally Hansen Lip plumper) and this is by far the best is actually works. OK so I haven’t exactly got the smallest lips in the world, but its makes the lines in my lip disappear and my lip do look at lot fuller and plump  They feel very pillowy and I adore the minty fresh feeling I get when I put it on  The packaging is like a shinny mirror which I like because it means if I don’t ever have a mirror on me I can just look into this.
I brought this Lipgloss about 2 months ago and I still have a lot left! And I use it religiously! It is damn expensive though! £25 for one lipgloss but I absolutely love this product and would pay this sort of money for plump cushiony lips  The consistency is quite thick but I think that adds to the feel of making it work  ABSOLUTE MUST HAVE PRODUCT!!

great product. i put a thick layer on before bed and wake with full lips!

Well color me shocked - I expected nothing and it actually delivered. With regular night time use, it's given me a little bit of plump, fine lines smoothed out, lips are softer.
If I hadn't randomly received a few packets of this with a purchase of something from an entirely different line of products, I would have never tried it. Have tried lip plumpers before and found them nothing special - tingly and at best, made my lips a little puffy for a few hours, if that,.
I opened a packet and immediately didn't like it - it's gooey, sticky, ultra high gloss - yuk. Didn't think I even got as much "tingle" and immediate temp plump from it. Then I read the instructions about it being more of a nighttime treatment and that with regular use, you would see benefits. My reaction - "yeah right" - to say I was skeptical would be an understatement. So I came to MUA thinking I would confirm what I suspected, but was surprised to see enough positive reviews that I thought I would go ahead and use the 4 sample packets everynight for as long as they lasted (a few weeks). So glad I did. Started to notice results after just a few nights, and after a few weeks I can say that for me - it has actually delivered. Nice, subtle, pretty results. Of course the list price is hideous, but I found some on sale on Amazon (about $34 instead of $50), and ordered a tube. The results are nice enough though, that I would have still bought at full price. I guess ya just never know.

I have been using this product overnight for about 3-4 months now. I have pretty full lips to begin in, but who doesn't want fuller lips? This is what I have been noticing.
1. THE SOFTEST LIPS OF MY LIFE! I have struggled before with flakey dry lips, despite exfoliating several times a week and applying some expensive lip moisturizer. But ever since using Lip Fusion XL my lips have been incredibly soft, kissable, and smooth. They almost looked airbrushed. I do wear nude lipstick everyday and love matte lipsticks and my lips look flawless when I apply lipstick in the morning. I don't use any other kind of chapstick, just Lip Fusion. I find that a lot of other lip plumpers (ie: Lip Venom) irritate the lips, but this does not.
2. Minor plumping. This product will not give you cheesy, duck lips that come from injections, and you shouldn't expect lip injection like results. I have noticed that the results I have from this are similar to how 'puffy' my lips get after bawling my eyes out for hours. My boyfriend noticed and commented that my lips were bigger after he came home after a month long business trip. The lines in my lip are smoothed.
This product will NOT give you Angelina Jolie lips if you have thin lips. The results will not be incredibly noticeable. Your lips will look like your lips, but better. Is this worth 50 dollars? For me it is, due to the moisturizing effects and the minor plumping. For me, this product works as my lips are slightly bigger. I will continue to repurchase as I am very happy with the results.

I don't like the price. I refuse to believe that they cannot sell this for less than what they are.
That said, this product works far better than any other plumper I've tried. It is not uncomfortable, at all. No stinging whatsoever. It isn't so sticky that I would avoid wearing it on a windy day.
My lips are rather full to begin with, but my upper lip is lacking in comparison to the lower. That's why I've tried so many plumping glosses. I've come to realize that no topical product is going to produce a dramatic change in size. BUT, this product definitely produces a noticeable difference. Without any help, my lips are pillowy.
But after using the Lipfusion XL, my lips look like overstuffed cushions. Only not weird, if that makes sense. They're also moisturized to the max, and very very soft. The color also seems to be a bit deeper.
I would not recommend that anybody go out and buy a full-sized tube. I would suggest a sampler. As with everything else, there is no guarantee that it will work for everyone. That said, I will repurchase when I run out.
I docked one lippie for the price.

After using this product for one week, overnight, I can say that it does what it is supposed to do but doesn't perform miracles. It *won't* change the basic size of shape of your lips, but it *will* thoroughly hydrate them, and do that better than any other lip treatment I have tried.
My two complaints are: 1. It is a sticky product. Apply just before bed and after brushing teeth. In the morning, you will have a little gunk at the inner lip line. Nothing horrible, but still......I guess that is the price you have to pay.
2. The actual price you have to pay. Waaaay expensive for what it is. Still, it works.

It seems that this product plumps in two ways.

First, about 10 minutes after application, it mildly stings the lips which causes them to swell somewhat. The sensation is mild (and I've rather grown to enjoy it actually). This first plumping effect wears off relatively quickly (within a half hour or so). But this product works more effectively as an overnight treatment.
Before bed, apply to bare, well moisturized lips. I am always sure to remove all oil (i.e. from my night cream when I use it) and add a bit of water or lick my lips thoroughly. This product works by attracting moisture to plump the dehydrated marine collagen particles in it, to rehydrate and make your lips fuller. (The product can also dry your lips over time if you don't moisturize with another product sometime during the day.)
So does it plump?? Yes! It isn't dramatic but it is definitely noticeable. After about 5 days, I started seeing lasting results so I switched to using it every other night to keep the results. I can feel my lips are plumper every time I rub them together and they definitely look fuller.
Interestingly, I got lazy about using the treatment overnight and started just wearing it as lip gloss every few days and you know what? One day I looked in the mirror and my lips were back to their previous (normal) size. So I went back to my old routine of using it overnight and I can see the difference once again....
I like the chrome-looking square tube and I like the fruity flavor. But I *love* the results. I don't like the price much, of course, but I would buy it again because it really delivers noticeable, lasting, semi-permanent results.
------------------------------
As a side note, last month at Trade Secret they were having a huge sale of many products that they are discontinuing, including LipFusion. LipFusion XL and the LipFusion colored glosses were $7 each! So call Trade Secret stores near you to see if they have remaining stock.
(I liked the glosses, too, but XL is, well, XL!)

I was really exited for this product after reading all the good reviews, but this was a disapointment,
I uses it for three nights, and countiued to use it thrueout the day, bur i couldnt really see any difference. It made my lips sligthly more red, and it gave them a wet look shine, but thats about it.
The gloss also dried iut pretty fast. After 1 hour you coulnt even see that i had put something else than lipbalm on my lips. Tha package is also awful! You cant see how much is left, and the aplicator is too small, so you have to dip it several times to cover all of your lips.
I will not buy this product again, but i will use it as a clear gloss if i want a bit more heavy look.

I received a very generous sample from Fusion Beauty when I liked them on Facebook. Then, I liked it, and bought some. First of all, I have little lips, and Lip Fusion does a good job puffing them up, if you want to use that phrase.
I apply it at night, along with Latisse. I notice softer lips, with more shape. I''ve noticed when I forget to use it, for longer than 2 nights, that my lips kind of go back to shrinkage.
It is pricey....but then, injections cost much much more, and have more side effects. It is like this: It works, I can tell a difference,and I am worth it.

Please see review for Sally Hansen Lip Inflation Extreme, As I wrote a pretty detailed review of LipFusion XL there and would rather not repeat myself here.... smart phone typing gives me thumb cramps....

I love this stuff. Yes, it's expensive (but getting lip injections is MORE expensive - so, it's actually cheap if you look at it that way).
I've been using this religiously every night for over a week and i notice fuller, more plump lips. before bed, i wash my face as usual and then, instead of putting aquaphor on my lips, i did a nice layer of this. (don't forget to brush your lips when you brush your teeth - i notice when i exfoliate my lips this works even better)
in the morning, my lips are noticeably plumper. in the morning, i apply either my clear lipfusion gloss, a colored lipfusion gloss or the lipfusion balm to keep the plumping action going throughout the day.
i don't think i will ever not buy this stuff again. i love love love it!
you can get the XL for about $30 at different websites (amazon, ACW, ebay). otherwise it's $50 at sephora, etc.

I've been using this product for over a month now and I can honestly say it doesn't work -for me-. In reality it's a gloss that seems to moisturizes and has staying power; but it most definitely has no plumping effect. I'm 20 years old and so I don't have an issue with lines or a loss of plumpness; what I wanted was poutier lips. And this product just didn't deliver. And for those who are curious about flavor/scent; there's a weird sweet/dental smell/taste to this. I really didn't like it. Maybe that's why it seemed to have staying power... I never wanted to lick my lips cause this stuff tasted pretty gross. I will not be repurchasing-that's for sure.
2 lippies because I didn't have a bad reaction and it works as a nice gloss.

After reading so many good reviews on this product I decided to give it a try despite the price tag. I have tried a lot of different plumping products before and always came to the same conclusion: none of them work, especially not long term.
The only reason I got it for this price is because I got a bunch of other samples and free gifts with it (from Sephora)... though it still doesn't justify the price tag. If I like it I will try to get it on sale next time.
*UPDATE*
After wearing this product for 4 days and 3 nights I have come to the conclusion that it is absolute crap. I cannot believe that I fell for the hype and actually spend $50 on a product that I thought would create miracles; something that you cannot achieve without plastic surgery or other types of injections.
This product does NOTHING for me. Sure, it moisturizes a little bit and looks nice when you're wearing it, but so does Vaseline and any other products that costs a fraction of the price of this piece of crap.
I am super disappointed that in 4 days of use I have not seen a single shred of change in my lips. I don't have very big lips, and mine tend to be very sensitive. I have always had problems with cracking, chapping, and peeling lips since I was a kid, which has resulted in a lot of lines on my lips. I basically have slightly dry lips all the time which is why I use a lot of lip glosses and such. Don't use a lot of lipstick and overly pigmented glosses because they settle in the lines.
I couldn't wait to try this product because it sounded like something I would really benefit from because so many people claim that it fills in the lines. Not for me. At all.
I will not return it only because I already said goodbye to the money, plus I don't like returning used products... so might as well keep it and use the rest of it as a lipgloss/moisturizer.
I don't actually believe that this product deserves such high reviews and get the feeling that a lot of ladies are giving it high scores to justify paying a freakin' fortune on a 0.29 oz tube of lipgloss.
Never again. This company should be ashamed of expecting people to pay $50 on such a mediocre product. Ugh!
I was going to be fair and give it more time to work before updating, but I think a few days is long enough for it to do something... Nope. Never purchasing again and will definitely give up on lip plumpers because I have spent a lot of money on such product and have yet to see one do something.
