Naturally found in the skin of humans and, in fact, all mammals, hyaluronic acid is a polysaccharide chain, which contributes to hydration and elasticity of the skin. Links between different Hyaluronic Acid polymer chains are promoted. On the other hand, less efficient links between portions of the same chain are minimized thanks to the advanced cross-linking process of Liquidimplant. The degree of cross-linking is then selected to provide a desirable level of durability in the skin. Optimizing all these properties provides a dermal filler with superior performance and patient satisfaction. This cross-linked Hyaluronic Acid is finely tuned with the size of the particles to produce a gel able to flow readily through a fine needle and to provide a soft, smooth feel to the augmented skin. The osmolality and pH of the gel are balanced to be compatible with the fluid in the skin, neither drawing-in nor releasing water, minimizing the need for over-correction. A slow expansion of the gel particles partly offsets the natural loss in dermal filler volume as time goes by, maintaining the level of correction.
