The groove that starts from the side of the nose wings and extends to the corners of the mouth is called the nasolabial line/groove. Weight changes become more noticeable with increased facial expressions and advancing age. It is the place where most fillers are applied. If these lines are obvious, you may look tired, unhappy or older. After nasolabial filler application, there will be no problems with your facial muscles and you can continue your daily life where you left off. The application is performed by injecting hyaluronic acid and peptide under the skin with a needle or cannula. Numbing creams are applied to the treated areas to prevent pain. Rarely, local anesthetic injection is required. Nasolabial filler application can be done alone or together with other area filler applications. The amount of filler to be used may vary depending on the size of the problem, but the effect of the application will appear immediately. In fact, after one side is done, you can compare it with the other unfilled side in the mirror. There may be redness and swelling for the first day or two. The best image appears within 3-4 days. A check will be made at the end of the first week. Rarely, bruising may occur after this application, which is performed with a needle. If it occurs, you can use bruise removal creams and concealer creams from pharmacies. The effect of nasolabial filling application will last for 15-18 months.
