Hello, grinding cheekbones is suitable for people with high cheekbones and low zygomatic arch. Because the zygomatic arch is located on the side of the face and the thickness of the zygomatic arch itself is limited, it is not suitable for grinding bones for people with high zygomatic arch. The lower angle of cheekbone plays a very important role in maintaining the normal face shape, so it is forbidden to grind all the lower angles of cheekbone when grinding cheekbone.
