Volume loss is the number one factor responsible for the facial changes associated with ageing. In youth, volume is created by a strong bony skeleton and supportive overlying fat pads which create harmonious fullness in all areas of the face. The ageing process means that bone gets reabsorbed and fat pads deflate. Furthermore, as tissues lose their support, they become lax and move downwards creating a sagging appearance. Fillers aim to replace the volume lost through bone reabsorption and fat pad weakening. The most commonly used ones consist of hyaluronic acid which is a naturally occurring substance already present in human skin. Depending on their manufacturing process, fillers vary in their consistency and firmness. These characteristics dictate their suitability for treating different areas of the face and addressing a number of aesthetic concerns. The more robust types of fillers are commonly placed deep into the cheeks where they act as anchors that help lift lower parts of the face upwards and consequently soften nasalabial folds and jowls. Their firm consistency means that they can also be used along the jawline, chin and nose in order to change the shape and contours of the face and create the appearance of a more flattering bony structure. Thinner, more delicate fillers are better suited for superficial placement in order to reduce wrinkles and improve the quality of the skin. For more information on filler treatments read here.
