摘要：
Disclosed herein are cohesive soft tissue fillers, for example, dermal and subdermal fillers, based on hyaluronic acids and optionally including proteins. In one aspect, hyaluronic acid-based compositions described herein include zero-length cross-linked moieties and optionally at least one active agent. The present hyaluronic acid-based compositions have enhanced flow characteristics, hardness, and persistence compared to known hyaluronic acid-based compositions. Methods and processes of preparing such hyaluronic acid-based compositions are also provided.
