Beauty is in the bone but not in the skin, a good-looking face must have a contour, and a face that lacks a sense of contour is missing a certain degree of beauty. The arch of the eyebrow supports the bone phase of our upper face, and a full arch of the eyebrow will visually give people a clear outline of the beauty of the curve, and at the same time, it also strengthens the bridge of the nose, the three-dimensional sense of the eye sockets, so that the eyes look deep and fascinating, which is the key to highlighting the beauty of the facial curves. What is the arch of the eyebrow? The arch of the eyebrow, also known as the “brow bone”, is a bow-like elevation located above the supraorbital rim and below the forehead. It is a bow-shaped elevation of the frontal nodes parallel to the supraorbital rim, and it is also the junction structure between the forehead and the orbit, and it tends to overlap with the eyebrows. The structural layers of the brow arch from the outside in are skin (including the brow hairs), subcutaneous tissue, and frontalis muscle and bone, with less adipose tissue. The brow arch is higher in Caucasians than in other races, and higher in men than in women. Oriental eyes are not as deep as those of Westerners, and this is directly due to the shallow sockets and low brow arches of Oriental people. The low arch of the eyebrow makes the bridge of the nose and the eye sockets less three-dimensional. What kind of people need eyebrow arch? People with underdeveloped brow bones are suitable; people with protruding eyes that make their eyes look dull are suitable. Underdevelopment of the forehead and brow bone is one of the facial features of oriental people. If the brow bone is very flat or even concave, the eyes are protruding instead, and they will look lifeless. Through the surgery of eyebrow arch augmentation, the eyebrow arch is raised, and visually the protrusion of the eyes is relatively low, which can improve the problem of protruding eyes. So what are the methods of brow arch augmentation? Autologous fat brow augmentation: excess subcutaneous fat cells are sucked from fatty parts of the body and processed into pure fat particles, which are then injected and transplanted into the arch of the eyebrow to achieve the effect of augmenting the arch of the eyebrow. Prosthesis brow arch augmentation: the use of prosthesis implantation to highlight the contour of the brow bone, increase the local three-dimensional sense, improve the local flat appearance, increase the sense of depth of the eyes, and improve the problem of protruding eyeballs. In the choice of surgical methods, usually brow arch augmentation is carried out by means of prosthesis implantation. Of course, different personal conditions make the suitable methods different, and some people usually confuse it with the problem of sunken eye sockets when judging their own brow arch problem. Therefore, when we choose brow arch augmentation surgery, we must choose a regular hospital and select a suitable surgery method under the diagnosis and advice of a professional doctor.
