The patient's expectations are extremely important in the application of lip fillers. This procedure is used to treat various issues such as asymmetry, cleft lip, and upper lip lines. As it is not a surgical procedure and the risk of complications is low, it is often chosen by people. With this method, asymmetry disappears and volume is given to the lips, which reduces signs of aging around the lips. The most important thing to consider in the process is that it is carried out by professionals in a well-equipped center. In procedures that aren't carried out by experienced doctors, undesirable outcomes such as unnatural, overly large, and misshapen lips can happen. Another important point is the quality of the filler product. It is not suggested for use in pregnant or breastfeeding women, as well as in people with coagulation disorders.
