The situation of diamond face is more complicated. If you want to change the face shape, it involves the correction of many facial parts, which can be divided into: upper facial plastic surgery Because the forehead of the diamond face is narrow and sunken, it is necessary to fill the forehead and temples. There are two methods: surgery and injection. The injection method does not require surgery, and can be filled with collagen or autologous fat, which generally has no rejection and good histocompatibility. It is also more convenient to draw materials. The surgical method is to make an incision in the hidden part next to the hairline, peel off a cavity under the temporal bone, and implant soft tissues such as dermis, fascia or muscle taken out of the body into the cavity. Pre-engraved silicone rubber prosthesis can also be selected. Shaping the cheekbones in the middle of the face determines the face contour of the middle face. Both the zygomatic process (the front of the face) and the zygomatic arch (the side of the face, extending from the zygomatic process to the temple) affect the beauty of the face. The rhombic face shows that the cheekbones are too large and too wide, thus causing the visual impression that the face is too wide. Zygomatic reduction is used to effectively reduce the zygomatic bone. Using special instruments and micro-precision surgery, the zygomatic bone designed before operation is thinned, thus reducing the facial contour. In addition, it can also improve bilateral zygomatic asymmetry and make the middle part of the face achieve an ideal aesthetic image. The lower part of the face is mainly mandibular angle plastic surgery, because the diamond-shaped face generally has no obvious mandibular angle, so the lower part of the face is relatively narrow. Mandibular angle plastic surgery needs to implant autologous bone tissue on both mandibular margins. If you want to pursue better results, you need to do chin augmentation surgery, that is, chin augmentation. People with diamond faces have narrow chins. If you want to change the sharp and narrow shape, you should widen and enlarge your chin. Chin plastic, short chin, skew, too prominent and other conditions can be better corrected. What women envy is an oval face or an oval face. In addition to the aesthetic standards of "three stops and five eyes" and the golden ratio, the contour curve should be beautiful. To change the ugly diamond-shaped face, choose face-changing surgery to make the face narrower and narrower.
