Lip fillers consist of synthesised hyaluronic acid (HA) or sodium hyaluronate, which is a natural component of lip collagen. The hyaluronic acid is a gel-like solution. Hyaluronic acid holds water which gives volume and hydrates the lips.  So HA's inherent water-holding properties restores a natural fullness to your lips.

 

Dermal Fillers are similar in many ways to Lip fillers. The difference between the lip fillers and  skin fillers is the number of cross-linked molecules per ml. In lip fillers, the number of molecules is 2-3 times higher allowing a more fluid look, which prevents lumps and uneven points.
