After reading Girl Gloss's post about the blogger's favourite lip products part 2., I began to wonder: 1. why they don't sell stila in my country 2. why MAC is so outrageously expensive here and 3. Don't You have any idea of the working mechanism of the lip plumpers!?
Basically, there are 2 type of lip-plumping products. The ones that irritate our lips, and the other, that try to affect the collagen produce or amount of the lips.
The ones contain potential irritants, like cinnamon oil (or extract), ginger (oil/extract), rosemary (o/e), menthol or other, no matter what kind of, but irritants! By irritating Your lips makes blood circulate faster, and causes swollen lips. As I've noticed, it often cause a little pain (sting, itch, whatever) on the lips, and to avoid this feeling, Your lips must be very-highly-precisely moisturized. I just couldn't imagine a girl having that moisturized lips without drinking 3 gallons of water a day, and applying lip balm any half an hour.
One of the irritating lippies is Clinique's Full potential lips gloss. I still have 2 tubes of it, one full size blossom shade and a little peach plump shade.
Others are just simply add something to the lip's natural collagen stock: using peptides, to stimulate the inner production, or by adding hydrolyzed collagen that can pick up some inner water. Peptides are not 100% effective, but the collagen...If it's the right formula, it can make You so much more confortable with Your lips.
Lipfusions contains hydrolized collagen - to be more exact, atelocollagen, that is tiny enough to get into the skin. Inside, they pick up some from the body's natural water, and getting much-much-MUCH more bigger than they were. This makes the little (I say little- they won't turn blade-lips into angelina lips) change on the lips.
My personal Favourit is the Lipfusion XL. Besides the collagen it contains hyaluronic acid, that gets into the skin too, grabs up some water, and holds it, keeps it close to the little collagen-booboos, and keeling it close to the surface, makes the lips much more moisturized. For me, it's the ultimate lip-plumber, and (as a new category) the ultimate overnite-lip must-have product.
To be honest, what I see is worth the price. I have different sized upper and bottom lips, and by making my upper lips much more visible, I'm ready to give that much money for a Lipfudion XL.
By the way, I think that lip plumpers must be tested by girls, who have different sized lips, like me. I certainty see the change, but my naturally-plumped-lipped girls just don't see the wonder, only can feel the super-hydrated feeling.
I can get it from the strawberrynet or similar sites (of course they don't sell them in here) about 40USD, but for me, applying every night, lasts nearly 6 months long. :)
...seems like WE totally agree :)
