Abstract
Abstract A hyaluronic acid-containing aqueous solution or aqueous dispersion of collagen having a pH of from about 6.5 to about 8.0 and an osmolality of from about 250 to about 320 mOsm/kgH₂O. The aqueous solution or the aqueous dispersion of collagen is useful as an agent for correction and reparation of a depressed part of or a void in soft tissue of mammals.
