Dermal fillers are injectable gels synthetically made to be structurally identical to their naturally occurring counterparts in our skin. They are made from hyaluronic acid (HA), which occurs naturally in the skin. HA’s structural matrix helps to keep the skin firm and moisturised by attracting 100 times its weight in water.
From our early 30’s onwards (and sometimes earlier depending on lifestyle factors) we start to lose the HA content in our skin. Collagen and elastin (which keeps our skin firm and elastic) is also lost as well as the fat contained in fat pads around our face. All of these contribute to the loss of support given to our skin, so inevitably our skin starts to sag, wrinkle and age. We also lose bone from our facial skeleton, most notably at the temples, maxilla (where the upper teeth attach to the bone) and along the jawline. This can further compound the loss of support.

Fillers can be used to replace some of the lost volume in our face and so help to support and moisturise the skin, leaving it looking less wrinkled and firmer. Thick fillers (High G Prime) can be used to mimic bony support particularly along the jawline and cheek.
