What Is a Double Chin?
A double chin, or submental fat, is a layer of fat that develops beneath the chin, often associated with excess weight . It can make you appear as though you have two chins, and is sometimes linked with a bit of weight gain but that’s not why it happens. Genetics, age, posture and skin laxity are all factors. For a lot of people, it’s an insecurity, especially when you see it on the side or in pictures.
What Causes a Double Chin
Several factors can lead to the appearance of a double chin, prompting the need for double chin treatments :
What Does a Double Chin Look and Feel Like?
A double chin can look like a pouched of soft fat beneath your chin or jaw line, which is usually more prominent when you tilt your head down or side profile.
This is the most visible sign of a double chin, one that may be hidden in daily routine but more noticeable in pictures or while gazing down. It could vary from a small flng of fat to a bigger layer, which can depend on weight, age, and genetics.
As fat deposits or skin laxity accentuates, the sharp angle of the jaw is rendered less sharp or disappears altogether. This may happen even without noticeable weight gain, from muscle atrophy, or the loss of collagen.
Aging, changes in body weight, or genetics can cause collagen to diminish and elasticity to break down over time, leading to the development of double chins and sagging skin.
In profile photos or mirror views, the bulge beneath the chin can look more defined. Many people first notice their double chin from side angles rather than head-on.
A double chin is nothing to be medically worried about, but if the aesthetic aspect bothers you you can seek advice from a cosmetic expert. They may suggest customized solutions to enhance contour and confidence.
Seeking Professional Help for Double Chin
A consultation may help to develop a personalized treatment plan to help you reclaim your jawline and minimise submental fullness. At the Harley Street Skin Clinic we have a number of treatments which are developed with the aim of safely and effectively re-contouring the area.
Both fat collection, muscle weakness and sagging skin can cause a double chin. Our skin elasticity drops as we age, as does the production of collagen, which in turn lets gravity take the skin south. At the same time, poor posture and genetics can cause muscles to weaken and the skin to become looser under the jawline. In some instances people of healthy weight can develop a double chin because of the way fat is distributed in their genes.
As part of the ageing process, your skin loses firmness, and muscle tone diminishes, making it harder to lose weight and combat a double chin . Weight gain makes fat accumulate around the body, including under the chin. Genetics can play a role in where fat is deposited, so some people may also inherit a predisposition for submental fat.
Others may feel less confident during social interactions or when their picture is taken as a result of the excess fullness beneath the chin.
Feeling that you are always aware of how your chin appears can bring emotional pressure or self-consciousness.
Most are self conscious about how they look or whatever angle they’re shooting in because of how the double chin looks, which is why some people resort to double chin exercises .
A double chin may develop along with, or be exacerbated by, poor head and neck posture, which may cause spinal imbalance over the long term.

Fat levels can easily cause double chins as the submental fat will be more visible as fat levels accumulate. Regular exercise and a healthy diet can prevent facial fat from settling in this region.
Practice good posture
When posture is bad, neck and chin muscles lose strength over time. Holding your head high and keeping your shoulders back tones the muscles and diminishes the skin folds beneath the chin.
Do facial and neck exercises
Exercises that target a double chin, such as chin lifts, jaw jutting and tongue presses, can help to tighten the area under the chin. In the long run this can help the lip gain more definition and diminish the sagging.
Avoid high-sugar and processed foods
Processed foods that are high in sugar can cause weight gain and bloat in the face. Fat digestion is controlled by eating wholefoods high in fibre, protein and healthy fats which can help to decrease fat storage under the chin.
Use firming skincare products
Consider using topical products containing peptides, retinol or caffeine that can increase collagen production and keep skin firm. Regular use may help minimize the appearance of sagging under the chin.
Get Enough Sleep
Restorative sleep aids collagen repair and fat regulation.
Not getting enough sleep can cause fluid retention and facial puffiness including under the chin. Deep sleep also plays a crucial role in skin regeneration and overall metabolic well-being.
Avoid smoking
Toxins in cigarettes break down collagen and reduces blood flow, resulting in early aging of the skin. This creates a greater risk of sagging, loose skin under the chin.
Massage the neck and jaw area
Increase circulation and encourage lymphatic drainage.
Light massaging on the chin can help promote circulation and minimize fluid retention, especially for those who are overweight . It can also tone muscles and promote improved skin texture over time.
