Hello and thank you for your question. A lip augmentation is a cosmetic procedure that uses an injectable dermal filler to enhance the appearance of your lips. The procedure is designed for anyone who is not satisfied with the appearance of their lips, and for patients who want more appealing, plumper lips. In the hands of an experienced injector a beautiful and natural look and feel can be achieved. Hyaluronic acid filers such as Juvederm and Restylane are the two most common dermal fillers that are used to create fuller lips. Hyaluronic acid is a naturally occurring sugar that gives the skin its natural elasticity and volume. Like collagen, hyaluronic acid decreases over time, and skin begins to lose its volume. An ultra-fine needle is used to inject the material into the lips and along the edge of the lips to make your lips fuller and plumper. Although the results are not permanent, you can expect your lips to retain the plump fullness for up to six months. I recommend scheduling a consultation with an experienced physician to discuss your options. Best of luck to you P. Alexander Ataii M.D.
