Aging causes loss of facial volume, descending soft tissue and decreased skin elasticity. The loss of facial volume is a result of diminishing dermal collagen, hyaluronic acid and elastin as well as fat atrophy and even skeletal bone loss. Facial contours change with age from high cheeks and a small chin to flattened cheeks and prominent jowls. Fillers contain synthetic hyaluronic acid and are used in different areas of the face to enhance volume and reduce appearance of wrinkles. Hyaluronic acid is a naturally occurring substance in the skin extracellular matrix that provides structural support and adds volume and fullness to the skin. The effect of most commonly used fillers last 6-12 months.
