Injectable collagen implant--update.

Injectable collagen implant (ICI), a new biomaterial reportedly useful for correction of scars and certain aging skin lines (wrinkles), was recently introduced. The purpose of this paper is to evaluate the safety and efficacy of this product. Data for this study were obtained from a survey which was sent to a group of cutaneous surgeons. They were asked about test site and treatment site reactions and about their satisfaction with ICI. The incidence of adverse reactions is low, and the severity of the reactions does not appear to be serious. The long-term benefit of ICI has not been established.
