While some people loathe thick and prominent lips, others consider full lips to be a sign of sexiness. In recent years, windy full lips have been featured in fashion magazine models as a symbol of sex appeal. As the skin ages, the upper lip becomes thinner and longer. Lip augmentation helps older professional women rejuvenate and restore their self-confidence. They can choose from injections, prosthesis or free grafts. A portion of the white lip is removed to raise the red lip margin, thus achieving a rejuvenating ratio of red lips to white lips. The mass media also does not present thin lips as a beauty feature. And the aim of pursuing thinness is often to achieve the same lip performance as the average person in order to overcome the quirkiness associated with thick lips. Filler injections Collagen injections We apply bovine and human collagen for lip injections. Although effective for only 4 months, the injection procedure is simpler than surgery and the recovery is quicker, which is favored by some. For these patients, cost is not an issue, as the cost of multiple injections is much higher than the cost of surgery. Some patients try lip augmentation injections to see the results and to get out of the surgical treatment, those who like the results may want to move on to a more permanent surgical procedure, and older patients often choose collagen injections to improve lip wrinkles. Autologous collagen Autologous collagen is an extract of liquid collagen from the patient’s own tissue, which can be obtained from the patient’s skin during a wrinkle reduction procedure and then sent to a laboratory for processing and extraction of the collagen for injection into the patient. The process can be time consuming and costly to transport. Restylene, which consists of injectable, non-animal-derived, stable hyaluronic acid, 20 mg/ml, the latter made by bacterial fermentation. Hyaluronic acid has a tremendous ability to bind water, forming highly viscous polyhydrides. The intercellular matrix of the dermis is the same for all races and is highly histocompatible, unlike collagen, which requires skin testing. Injections can be painful and sometimes require local anesthesia. Injections may produce surface unevenness, but this will improve with time. The effect lasts for more than 6 months. Hylaform This is a hyaluronic acid extracted from the crown of the rooster, with a higher molecular weight and a lower concentration of 6mg/ml. Fat injections Fat injected into the lips disappears more quickly than other areas. Injecting into muscle tissue will increase the survival rate. It is also important to control the injection volume and “leveling” during the injection process, generally centered on the upper lip edge and the lip bead. The surviving fat will survive for a long time. Surgical lip augmentation 1, prosthesis implantation 2, allogeneic dermis Allogeneic dermis is a non-cellular dermal matrix derived from human skin. The cell-free matrix serves as a template for fibroblast and endothelial cell growth. 3.Teflon Among the many prostheses, expanded fibrous PTFE is used as lip augmentation material. The Sam surface prosthesis is a flake prosthesis that can be cut to a predetermined size. Ultrasoft is a hollow tube that allows the tissue to open into the cavity. 4.Pre-operative consultation Before surgery, patients should understand the advantages and disadvantages of various prostheses to make the right choice. The patient should also be aware of the temporary nature of the allograft dermis and the possibility of access to the prosthesis. 5.Post-operative care Ice packs should be applied to the operated area for 2 days, especially for allografts, and broad-spectrum antibiotics should be applied for 1w before and after surgery, and lip activities should be reduced for 1w, and strenuous lip movements such as whistling, kissing, opening the mouth wide and grinning should be prohibited within 1m. Prevent food from touching the wound area when eating. 6.Recovery The swelling is obvious in the first 3 days, accompanied by salivation, the swelling will subside within 1w, and hard nodes may appear, lasting 6m. It is seen in a small amount of Ultrasoft.
