Injectable fillers are commonly used in Plastic and Reconstructive Surgery to correct serious and slight aesthetic defects due to their low invasiveness and an easy implant technique procedure. Synthetic hydrogels are proposed as filler materials for their similarity with soft tissue and to avoid many disadvantages of naturally derived materials such as short persistence, allergenicity, and immunogenicity. Our studies are focused on the biocompatibility evaluation of a polyacrylic hydrogel containing alkylimide-amide groups and pyrogen free water (96%) (Bio-Alcamid(R)) by means of the in vitro cytotoxicity and mutagenicity assays and the in vivo skin irritation, sensitization test, and subcutaneous implant. All tests conducted on Bio-Alcamid(R) showed no toxicity. It is a substance easy to inject and remove; it does not migrate, and its safety allows it to be a suitable filler for the correction of slight and also very serious aesthetic defects.
