Double Chin

Submental fullness, the soft tissue under the chin commonly called a double chin, blurs the line between the jaw and the neck. It is one of the most weight-independent concerns we see: slim, fit people can carry a stubborn pocket of submental fat purely because of genetics or bone structure.

Because several different tissues can be responsible, contouring this area is not one treatment. The plan depends on whether the fullness is fat, loose skin, a weak jawline, muscle banding, or a combination.

Genetics determine where the body stores fat and how much support the jaw provides. A recessed chin or a smaller mandible makes even a modest fat pad look more prominent. Weight change contributes, but rarely explains the whole picture.

With age, skin loses collagen and elastin and the platysma muscle of the neck slackens, so tissue that was once held taut begins to descend. Posture and prolonged screen use can accelerate the appearance of laxity in the same area.

During the consultation, we assess the area in profile and in motion: a pinch test for fat volume, a skin-snap test for elasticity, and an assessment of jaw projection and platysmal banding. We also review your medical history, thyroid function where relevant, and any prior treatment or surgery in the neck.

That assessment determines the order of treatment. Reducing fat in skin that has poor elasticity without addressing tightening can leave the area looking looser, so sequencing matters as much as the treatment choice.

Belkyra (deoxycholic acid) is an injectable that permanently destroys fat cells in the submental pocket. It is delivered in a grid of small injections across the treatment area and works best on well-defined fat with reasonable overlying skin quality.

Swelling after treatment is expected and can be pronounced for several days, which is part of how it works. Most people need more than one session spaced at least a month apart, and the results build gradually as the body clears the treated cells.

Where the underlying issue is projection rather than volume, structural filler along the chin and jawline can restore the angle between the jaw and neck. Adding support at the chin point lengthens the profile and visually tightens the submental area without removing anything.

This is often the difference between a good result and a great one, particularly for patients with a recessed chin who would otherwise see limited change from fat reduction alone.

When loose skin is the dominant feature, energy-based tightening is the priority. Radiofrequency and radiofrequency microneedling stimulate collagen in the dermis, firming the skin envelope over a series of sessions.

Neuromodulator injections can soften prominent platysmal bands that pull the jawline downward, smoothing the transition from jaw to neck. Results from tightening are progressive and typically peak around three months.

Most submental plans combine two or three modalities across several months: reduce the fat, support the jaw, then tighten the skin. Treating one element in isolation is the most common reason people feel underwhelmed by results elsewhere.

We stage treatments so each has time to settle before the next is judged, and we photograph progress in profile so you can see the change objectively rather than by memory.

Non-surgical contouring suits mild to moderate fullness with reasonable skin quality, with no general anaesthetic and no meaningful downtime. It asks for patience: results arrive over months, not days.

Significant skin laxity or a large fat volume may be better served by surgical options, and we will say so plainly at consultation rather than sell you a series that cannot reach your goal.
