Cosmetic lip fillers, fat transfers, and lip implants are different ways by which you can augment your lips- create fuller lips. Lip fillers contain hyaluronic acid or collagen protein derived from bovine or animal. In fat transfers, the extra undesirable fat is taken from any fatty body parts and injected into the lips. Lip implant is a surgical method in which incisions are made and lip implants are placed to enhance the lip's shape and size for a lifetime.
