According to the American Academy of Aesthetic Plastic Surgeons, 1,448,716 people received hyaluronic acid (HA) injections by plastic surgeons in 2007 (Table 23-1). The actual number is likely much higher when factoring in procedures performed by dermatologists and other aesthetically oriented physicians and physician extenders. Although collagen products (Zyplast and Zyderm) were the first dermal fillers to become widely available, collagen fillers have largely been replaced by HA fillers.
