Fillerina Lip Plump is a roll-on lip gel that is said to give you fuller, more pouty lips with results that last. It is not a temporary lip plumper, but rather works gradually and lasts for 3 to 4 months with reduced use. Fillerina Lip Plump promotes the increase of lip volume due to the filling and plumping properties of its 6 hyaluronic acid molecules with different molecular weights (from 1000 Dalton to 2 million Dalton). Hyaluronic acid can provide these effects because of its ability to absorb and hold water. In fact, hyaluronic acid is able to hold more water than any other natural substance—up to 1,000 times its weight in water. This is possible because hyaluronic acid is a glycosaminoglycan (GAG), a long polysaccharide (sugar molecule) composed of disaccharides called amino sugars and uronic acid. GAGs are negatively charged and thus tend to attract positively charged sodium and potassium ions. In turn, this causes the GAGs to absorb and hold a large amount of water. Applying Fillerina Lip Plump will help to attract moisture to the lips, resulting in smoother, softer lips with decreased wrinkles and a more plump appearance.
