Hyaluronic acid fillers: Restylane and Perlane

Abstract

The list of injectable skin fillers available for soft-tissue augmentation is constantly growing, giving aesthetic surgeons more options in the treatment of scars, lines, and wrinkles. Various products for soft-tissue augmentation are currently available in the United States based on hyaluronic acid. One should keep in mind that for these hyaluronic acid gel to have the desired longevity they must have repeating chemical bridges to withstand the constant mechanical and chemical enzymatic degradation to which they are subjected once implanted. Restylane and Perlane have proved to be safe, effective, and liked by patients. The Restylane family of products is currently expanding and soon practitioners will be able to have a diversified arsenal of cross-linked hyaluronic acid products to rejuvenate the aging face.
