Face filling is a cosmetic procedure used for aesthetic purposes such as reducing wrinkles, correcting or clarifying facial features, removing volume loss or plumping lips. This process is carried out using a series of substances called fillers. Fillers are usually made of materials such as hyaluronic acid, calcium hydroxylapatite, polylactic acid or polycaprolactone. These substances, when injected under the skin, help to achieve the desired results by filling the Cavities under the skin or increasing the volume of the tissues under the skin. Facial filling is a safe procedure that is usually performed by a dermatologist or plastic surgeon. During the procedure, the filler is injected into the selected areas through a fine needle or injector. The procedure is usually done under local anesthesia and usually takes between 15 and 60 minutes, but the time may vary depending on the type of filler applied, the area of application and the desired result. Facial fillers usually require minimal recovery time and patients can usually return to social activities immediately. However, side effects such as mild swelling, redness or bruising may occur after the procedure, but these usually go away within a few days. Facial fillers can have a temporary effect and results usually last between 6 and 18 months. At the end of this period, the filler is naturally absorbed by the body and its effect decreases. Patients who want to maintain the effect of the filler may need regular renewal procedures.
