Alloplastic injectable biomaterials for soft tissue augmentation: a report on two cases with complications associated with a new material (DermaLive) and a review of the literature

A wide variety of biological and alloplastic injectable biomaterials are available for soft tissue augmentation, but the ideal material has not yet been discovered. Biological materials such as collagen and hyaluronan yield temporary results, while injectable alloplasts are apt to cause varying degrees of foreign body reactions that may result in lumps and chronic inflammation.
