Lip augmentation procedures enhance the fullness of lips and make them more attractive. Like the rest of our skin, our lips loose collagen and fat during the aging process. Other factors which accelerate the signs of aging around the lips include smoking and sun exposure. Lip augmentation is an ideal procedure for patients who have always had naturally thin lips that they are self-conscious about, and also for those who want to return their lips to the shape and fullness they had when they were younger. This is accomplished by implanting synthetic or biological materials into the lips to make them plumper and more appealing. Most people who are thinking about a lip enhancement procedure want fuller lips that are smooth, plump, wrinkle-free and youthful looking. If you are interested in lip augmentation, you have a variety of options. These include lip augmentation surgery, and injected substances. Lips may be injected with collagen or with fat transferred from another site in the patient's body. Both liquid collagen and fat are absorbed and repeat treatments are necessary to maintain results.
