Conventionally, the ideal chin is thought to be one that extends to just behind a vertical plane dropped from the vermilion border of the lower lip in the profile view (1–3) (Figure 1A). A chin that fails to do so is considered to be deficient, requiring augmentation.
Your chin should have enough projection that if you hold a pencil straight against the front of your lips, it touches the tip of your chin. If your chin lies behind the pencil, your chin is recessed and your profile looks weak.
Ideally, the front most point of the chin is approximately in the same vertical plane as the lips when looking at a person from the side. You can see this by having someone take a profile picture of you. Another useful tool is called the Rickett's Esthetic Line.
Some people are born with a receding chin, and children often grow out of it as their bones grow. But other people develop a weak chin over time. A pronounced overbite may lead to a weak chin and a weak jawline. Age might, too.
Optimal chin projections are somewhat subjective and rely on other factors like overall facial measurements, nose size, and the patient's height. But as a rule, considering an individual's profile, the front of the chin should come close to an imaginary vertical line drawn down from the extreme edge of the lower lip.
Diamond. The diamond shaped face is the rarest of face shapes, and is defined by a narrow forehead, wide cheekbones and a narrow chin.
Bone – The ideal mandibular angle is sharp and full, and the front of the chin projects to about the level of the lower lip when you look from the side.
The mental crease, or labiomental sulcus, is the horizontal crease underneath your lower lip and above your chin.
The labiomental fold is a transverse indentation of the face, which marks the intersection of the lower lip and chin. It plays a significant role in movement of the lower lip and in facial expression.

Large Chin: A large chin is primarily a personal aesthetic concern. If the size of the mandibular protuberance is disproportionate to other facial features, or overpowers the jaw and mouth area, one may feel their chin is too broad.
Prolonged poor posture—often characterized by a forward head and rounded shoulders—can lead to neck pain, a neck hump, and postural kyphosis, an abnormally curved spine. Tucking the chin helps reverse kyphosis by putting the upper cervical vertebrae into flexion and the lower cervical vertebrae into extension.
A weak chin, which people may call a recessed chin, refers to a chin that does not have a prominent appearance on the face or jawline and may appear to slope backward from below the mouth. In some cases, a weak chin may result from genetic factors.
A weak jawline is defined by its rounded angle and soft edge. A common characteristic among those with a less pronounced jawline is that the mandible, the lower jaw, is often set further inwards – towards the neck – rather than outwardly protruding.
A recessed chin is a chin that sets further back than the ideal. It's also called weak chin. Generally, when you have a strong chin, it gives you a more defined jawline, and this can look both more feminine and more masculine, depending on your face.
Marionette lines are vertical lines that run from the corners of the mouth to either side of the chin or jawline. They're caused by multiple factors such as: A decrease in the production of collagen and elastin. As we age, we produce less of these two substances which are important in keeping the skin tight and smooth.
The Most Common Causes of Lip Lines
Fine lines mainly occur because of aging and sun exposure. Sun exposure accelerates the aging process, and aging means we lose volume in our face and lips. As the volume dissipates, the lines appear. The skin is literally folding.
The vermilion border (sometimes spelled vermillion border), also called margin or zone, is the normally sharp demarcation between the lip and the adjacent normal skin. It represents the change in the epidermis from highly keratinized external skin to less keratinized internal skin.
Marionette lines run from the outer corner of the lips to the outer corners of the chin and naturally develop over time. Many of our clients want to correct these lines and find treatment to help them achieve a youthful-looking appearance, as marionette lines can cause the face to look saggy.
Perioral wrinkles are the fine or deep lines that occur around the mouth and lips. As we get older this area is often one of the first to develop wrinkles. Like most wrinkles on the face, sun exposure, genetics and smoking (smokers lines) are strong contributors to the development of these wrinkles.
We all have them, though it's puzzled biologists for a long time as to why we do. I'm talking about that odd little groove found below your nose that runs to your top lip. Technically, it's known as your philtrum and it's as ubiquitous to the human face as the nose or eyes.
A captivating chin may have a strong jawline, a defined jaw angle, and a smooth and proportionate profile. A chin that is attractive may have a balanced and harmonious relationship with the other facial features, such as the nose, cheeks, and lips.
Striking facial features look very masculine and attractive. A clearly defined chin line and jawline makes the face look more masculine and youthful. However, not everyone has a prominent chin line, and even if they do, it loses elasticity and volume with age.
The male chin is wider, angular and more protruding than the female chin. Women's chins are generally rounded, smoother and softer in appearance. The shape of the chin is an crucial aspect of gender recognition and critical factor for achieving the objectives of facial gender confirmation.
