Ancient people often use the phrase “the sky is full and the earth is square” to describe a person’s face is good. The so-called good face and evil face refers to the feeling of goodness or evil at first glance, giving people the impression of mildness or aggressiveness. The fullness of the heavenly court means that the upper, middle and lower part of the forehead grows wide, even and more prominent, and the temporal part is not depressed. Generally speaking, the upper part of the forehead is the main reasoning, the middle part is the main memory, the lower part is the main intuition, if the three are even and full, it means that the person has a good physiological basis for intellectual development. In a good face, the forehead position of the heavenly court accounts for a large proportion. Facial science believes that people with a full heavenly court have more noble luck and are often promoted by others to obtain a successful career. In recent years, the technology of autologous fat filling has been developing rapidly. Autologous fat breast augmentation, buttock augmentation and facial filler can all achieve good results. Forehead and temporal fat filler can make forehead full, but fat filling forehead is the most difficult because forehead bone is almost a smooth plane and its surface is covered by only a very thin layer of soft tissue. Injecting a layer of fat under such a thin skin, if the amount is uneven, it is easy to show an uneven forehead, a difficulty that does not exist in breast augmentation and buttock augmentation.
