There is no such thing as what works well with facial fillers. Commonly used facial fillers include hyaluronic acid, autolipids, and prosthetics, but due to the variability in an individual’s physique, it is impossible to generalize as to which one should be chosen. Facial fillers are a type of treatment used to compensate and improve facial depressions, or lack of facial height. Common materials include hyaluronic acid, autologous fat, and prosthesis. Their materials are different and patients can choose the right procedure according to their own situation. Hyaluronic acid facial filler is mainly by injection, hyaluronic acid material is injected into the local skin, by increasing the volume of subcutaneous tissue to support the facial depression and unevenness, which can realize the role of filler. Or it can be filled by autologous fat filler and autologous tissue filler, where the fat from the parts of the body with much fat, such as abdomen, buttocks, thighs, etc., is extracted and injected into the localized skin depressions after being specially processed into pure fat particles, which can make their face flat. Some patients can also choose prosthesis, mainly solid medical silicone, expanded polytetrafluoroethylene, high-density polyethylene and other materials, which will be filled into the required areas, so as to achieve the effect of plastic surgery. For patients who have the need for facial fillers, they need to visit a regular hospital and take treatment measures under the guidance of a doctor.
