Abstract: Beads for use in dermal filler polymers, which are characterized in that they are spherical, have an average diameter between about 40 microns and about 500 microns and range in diameter between about 20 and about 900 microns. The present invention further includes each of a dermal filler incorporating the beads, an apparatus containing the dermal filler along at least one filler polymer, which is hyaluronic acid or a derivative thereof, and a method for injecting the dermal filler nasolabial skin folds of a patient's face.
Abstract: A biocompatible, degradable dermal filler system is composed of unmodified macroporous chitosan microbeads dispersed uniformly in a continuous phase composed of cross-linked hyaluronic acid gel particles and unmodified hyaluronic acid.
