Over the past decade, the use of nonsurgical products and devices to correct facial contour defects and signs of skin aging has exploded with new lasers, toxins for muscle relaxation, and dermal fillers revolutionizing aesthetic medicine. Of all the nonsurgical modalities employed during this period, the dermal filler industry has seen the most growth in demand. In 2006, the worldwide market for dermal fillers increased by 19%; and the US market is expected to increase a further 20% to 25%. This is due in large part to new products, particularly the hyaluronic acids such as Juvéderm, which now promise greater longevity, fewer side effects, a more natural appearance, and easier administration.
