Diamond face is a special face, which is characterized by prominent forehead and cheekbones, while relatively depressed eye sockets. The prominent cheekbones make the temples and cheeks depressed and flat, while the nasal roots are relatively flat. This kind of face is often called a rhombic face because its overall outline is rhombic. The characteristics of rhombic face make the facial contour unique and easy to identify. For people with this face shape, appropriate hairstyles and makeup artists can help balance the proportion of the face, such as choosing appropriate hairstyles to reduce the protrusion of forehead and cheekbones, or adjusting the shadow and light effects of the face through plastic surgery and highlights.
