Dermal fillers are smooth injectable gels used to restore or add volume to the face. Fillers vary in density (thickness) which determines which area they can be used in and helps achieve the desired result, whether that is to provide lift or contouring, create symmetry, or enhance a particular feature such as the lips. Many dermal fillers contain a compound that mimics the properties of a naturally occurring sugar molecule. This particular molecule assists in skin firmness and smoothness, by providing a kind of supporting network for other important structural tissue components, at the same time drawing moisture to the area and holding onto it. Over time, our natural levels of this compound diminish, which is where fillers can help – literally filling wrinkles and hollow areas from within.
