Many people are surprised to notice fullness under the chin even when they’re slim, so why do I have a double chin, but I’m skinny? Dr Ayad Harb explains that this is a common concern and not always related to body weight. Several factors, including genetics, posture, bone structure, and skin laxity, can contribute to the appearance of a double chin even in those with a lean physique.
In many cases, a double chin is caused by fat distribution influenced by genetics. Some people naturally store small amounts of fat beneath the jawline, while others develop one due to weaker bone structure or a shorter chin, which makes the area appear less defined. Ageing is another factor, as collagen and elastin decline, the skin can lose its firmness, allowing tissue to sag and create the illusion of fullness under the chin.
Dr Ayad explains that modern lifestyle habits also play a role. Poor posture, particularly from looking down at phones or screens, can weaken neck muscles and cause skin to fold. This repetitive downward angle, often called “tech neck”, can make the chin area appear heavier even without fat accumulation. Hydration, diet, and sleep quality can also affect how firm and lifted the skin appears.
Non-surgical treatments have made it possible to contour and tighten the lower face without invasive procedures. One of the most effective modern options is Endolift, a laser-based treatment that targets both fat reduction and skin tightening in a single session.
Endolift uses a fine laser fibre inserted just beneath the skin to melt small fat deposits, stimulate collagen, and tighten surrounding tissue. This dual effect helps lift and contour the jawline while improving skin firmness. Results appear gradually over several weeks and continue to improve as new collagen develops. The procedure is performed under local anaesthetic, involves minimal downtime, and provides long-lasting definition for both men and women who want sharper, more sculpted contours.
Often, it’s due to genetic structure, minor fat deposits, or skin laxity, not excess weight. Treatments like Endolift can effectively address these underlying causes, helping to restore a more defined jawline and balanced facial profile, all without surgery.
Even if you’re slim, you can reduce a double chin through targeted non-surgical treatments and lifestyle changes. Procedures like Endolift can precisely melt small fat pockets and tighten the skin beneath the chin for a sharper contour. Improving posture, staying hydrated, and maintaining good skin elasticity can also make the jawline appear more defined. However, when genetics or mild laxity are the cause, professional treatment usually delivers the most visible results.
A double chin may improve slightly with lifestyle changes such as weight management, facial exercises, and posture correction, but it rarely disappears completely without targeted intervention. If the cause is skin laxity or localised fat, treatments like Endolift or other skin-tightening lasers can permanently reduce fullness and lift the area. Once the excess tissue is treated and collagen production is stimulated, results can be long-lasting with proper care.
Yes, sleep can influence how your face looks. Poor sleep may cause puffiness, fluid retention, and reduced collagen production, making facial contours appear softer or heavier. Consistent, high-quality sleep supports healthy circulation, helps balance hormones that affect fat storage, and keeps skin firm. While sleep alone won’t remove a double chin, it plays a key role in maintaining overall facial definition and skin tone.
