Cervicomental angle
The cervicomental angle refers simply to the angle between the neck and the chin from side-on. This angle is well-defined in some individuals, almost 90°, but less well-defined in others. This is often due to the natural shape of the face, its bone structure (for example a receding chin or « retrogenia »), and its anatomy, but other factors can come into play.
With time, our skin naturally loses tone and elasticity due to a decrease in the production of collagen and elastin fibres responsible for the suppleness and firmness of our skin.
Generally speaking, a young face is shaped liked an upside-down triangle known as the triangle of beauty. As the skin ages over the years, it begins to sag, changing the contours of the face and inverting the volumes; the lower part of the face becomes squarer. In women, the menopause can affect the sagging of the tissue.
Sometimes, fat deposits of varying sizes can settle under the chin (trivially known as a « double chin »). This excess fat further accentuates the blurring of the cervicomental angle and can be difficult to eliminate.
We also know that the quality of the skin is weakened by external factors such as excessive consumption of tobacco or alcohol, or sun exposure. The angle between the neck and the chin blurs, and the harmony of the face changes resulting in a tired, less gracious appearance lacking dynamism.
