Hyaluronic acid fillers in facial rejuvenation.
Nonsurgical procedures have become very popular for the rejuvenation of the aging face. Trends now are for less invasive procedures as well as for more preventative intervention to slow the damage from ultraviolet light and environmental factors, as well as from intrinsic aging. The goal of these procedures is to eliminate or delay the need for corrective surgery. The regular use of sunscreens; retinoids and improved cosmeceuticals; injectable neurotoxins; soft-tissue augmentation products; and minimally invasive laser, light, and radiofrequency treatments are decreasing and delaying need for invasive procedures. Injectable fillers entered mainstream cosmetic medicine with the development of bovine collagen injections in the 1980s. The availability of improved fillers that are less allergenic and longer lasting has resulted in a renaissance in filler techniques. No single filler has proven to be more popular than the category of hyaluronic acids (HA). This article will review the use of the hyaluronic acid fillers that are currently approved for use by the Federal Drug Administration in the United States and describe the significant differences between them to assist the practicing cosmetic physician in choosing and using this category of dermal filler.
