Have you ever glanced in the mirror and been surprised to find a shadow-like fullness beneath your chin, thinking “wait, is this a double chin?” A double chin can become noticeable due to various factors — age, bone structure, and postural habits — even without being overweight. Left as is, it can blur your facial line and give an aged impression, so if it concerns you, we recommend starting care early. This article details the causes of a double chin, resolution methods, and KADOMORI’s recommended treatments.
What Causes a Double Chin?
A double chin that concerns you every time you look in the mirror. You might tend to think “is it because I gained weight?”, but that’s actually not the only cause. Various factors are involved, including bone structure, weakened muscles, postural habits, and lifestyle habits. First, let’s introduce the main causes that unknowingly create a double chin.
A Small Chin
If a double chin concerns you but you can’t find weight gain or age-related sagging, it may be caused by a small chin. When the jaw bone is small, the distance between the neck and chin tip shortens, so even slightly looking down can easily fold the skin, making it look like a double chin. Regardless of body type or age, there are cases where a double chin becomes noticeable due to bone-structure influence. When the original contour is the cause, training the facial-line muscles or being mindful of a posture aware of chin position can lead to improvement.
Influence of Obesity
A well-known cause of a double chin is excess fat, meaning the influence of obesity. The human body has “subcutaneous fat” just beneath the skin and “visceral fat” around the internal organs, but a double chin is mainly related to subcutaneous fat. When fat accumulates under the chin, the facial line blurs, making it look like a double chin. Not just fat directly on the face, but whole-body weight gain can also have an influence, so reviewing your diet and exercise habits is important.
Weakened Expression Muscles from Aging
Weakened expression muscles from aging is also one cause. When facial muscles weaken, they can no longer firmly support the skin and fat, causing sagging beneath the chin. Also, the facial bones gradually shrinking with age, or subcutaneous fat shifting, is also related to facial-line looseness. Gradually activating your muscles through expression-muscle training and massage you can continue without strain is important for prevention and improvement.
Posture
Your everyday posture can sometimes be a cause of a double chin. Continuing a downward-looking posture for long periods, like when looking at your smartphone, pushes out the fat and skin under your chin, making a double chin more likely to form. Once that state becomes habitual, the double chin can become harder to resolve even after correcting your posture. Being mindful daily of stretching your neck, keeping your back straight, and holding your phone higher naturally leads to a cleaner facial line.
Poor Tooth Alignment
Tooth alignment and a double chin might seem unrelated at first glance, but they can actually be deeply connected. Poor tooth alignment tends to affect your bite, creating imbalance in how the muscles around your mouth and jaw are used. As a result, the facial line can become more prone to sagging, or muscular imbalance can make fat more likely to accumulate under the chin. Orthodontic treatment or bite adjustment can balance the whole face, sometimes leading to improving a double chin. Tooth alignment is an important point not just for beauty but for health too.
How Can You Resolve a Double Chin?
A concerning double chin can be expected to gradually improve through care. Recently, more people are choosing cosmetic medicine too, making it possible to take countermeasures suited to your lifestyle. Here we introduce various methods for cleaning up a double chin, including hyaluronic acid injections, reviewing posture, and dietary approaches.
Hyaluronic Acid Injections
Hyaluronic acid injections are popular among those who want a cleaner facial line. Injecting hyaluronic acid to refine the jaw’s contour makes the jaw look tightened, easing the impression of a double chin. For those with a naturally small chin, it’s effective as a shape correction. Treatment finishes quickly, and being able to feel change right away is also one of its appeals. However, since the effect doesn’t last forever, maintenance every few months to half a year is needed. While downtime is minimal, internal bleeding or redness can occur, so watch your condition after treatment.
Postural Improvement
Everyday posture can sometimes create a double chin without you realizing it. When looking at your smartphone or computer, do you find your neck jutting forward or adopting a downward-looking posture? Continuing this posture makes fat and sagging more likely to accumulate under the chin. To prevent a double chin, first being mindful of correct posture is important. Just keeping your back straight, tucking your chin slightly, and being mindful of a posture where your neck extends can change the impression of your facial line.
Dietary Improvement
One cause of a double chin is excess fat accumulating on the body. For this reason, reviewing your diet is very important. No special diet is needed — the basics are getting a balanced intake of vegetables, protein, and carbohydrates. Watch your intake of greasy or sweet foods. Also, pay attention to your posture and breathing during meals. Continued mouth breathing makes the muscles around the mouth harder to use, potentially leading to sagging. Being mindful of nasal breathing also naturally trains your facial muscles.
