Lip augmentation encompasses a broad range of procedures from simple injections to surgical implantation of permanent implants.
Temporary injectable fillers used for lip augmentation include a wide variety of natural and synthetic compounds (also see section on dermal fillers) such as bovine (cow) collagen, human (foreskin) collagen (Cosmoplast), human (cadaver) collagen (Cymetra), hyaluronic acid (Restylane), and fat.
Fillers such as silicone and polymethylacrylate (Artecoll) are permanent fillers sometimes used for lip augmentation. Implants are more permanent methods of lip augmentation and require surgery.
Most of the implants are made of expanded polytetrafluoroethylene (ePTFE) and can be removed if needed.
