What Is a Double Chin and Sagging Neck?

A double chin, or submental fullness, typically results from localised fat beneath the chin, which can be influenced by ageing, genetics, or weight changes. A sagging neck, on the other hand, is usually caused by a loss of collagen and elastin, leading to loose, crepey skin and reduced firmness.

At The Axis Clinic in North London, we offer a tailored, non-surgical approach to address both concerns, combining advanced fat-reduction, contouring, and skin-tightening treatments to redefine the jawline and rejuvenate the neck.

What Causes a Double Chin & Sagging Skin?

A double chin and sagging neck can develop for several reasons, most commonly as a result of ageing, genetics, and changes in skin elasticity. As collagen and elastin production naturally decline, the skin begins to loosen, and fat may accumulate beneath the chin, creating the appearance of fullness or heaviness around the jawline.

Genetics can also play a key role, making some individuals more prone to developing submental fullness regardless of their weight. In addition, weight gain or poor posture can weaken the neck muscles and accentuate the appearance of a double chin over time

Common signs of a double chin and sagging neck include:

  • Visible fullness beneath the chin or along the jawline

  • Loose or sagging skin on the neck

  • Reduced definition between the jawline and neck

  • A heavier or drooping facial appearance

FREQUENTLY ASKED QUESTIONS

Both men and women are equally likely to develop a double chin. Factors such as ageing, genetics, and weight changes play a greater role than gender in determining who is affected.

Yes. At The Axis Clinic, we specialise in non-surgical and minimally invasive treatments such as QuantumRF, FaceTite, and Morpheus8 that reduce fat, tighten skin, and redefine the jawline without the need for surgery.

Most patients begin to notice a visible reduction in their double chin within two to four weeks after treatment. As the tissue continues to contract and new collagen forms, results become progressively more defined over the following months, with optimal improvement typically seen around six months after the procedure.

To minimise swelling after treatment, keep your head elevated for the first few days, using extra pillows or sleeping in a slightly upright position can help. It’s also best to avoid excessive chewing or talking for 48 hours and opt for softer foods while the area heals. Gentle cold compresses and staying well-hydrated can further support a comfortable recovery and quicker reduction in swelling.

Downtime is minimal. You may experience mild swelling, redness, or tenderness for a few days, but most patients return to normal activities within 24–48 hours.

Yes. Both QuantumRF and FaceTite are minimally invasive procedures with significantly shorter recovery times compared to surgical options. Most patients can return to work and normal activities within a few days, while surgery often requires several weeks of healing. Minor swelling or tenderness may persist temporarily, but downtime is minimal.

Results can last between 18 and 24 months, depending on your skin type, lifestyle, and the treatment performed. Maintenance sessions may be recommended to prolong your results.

These treatments are generally comfortable. Local anaesthetic or numbing cream is applied before the procedure to minimise any discomfort and ensure a smooth experience.
