Ageing is inevitable—but saggy neck skin and a double chin don’t have to be. Many people begin to notice a loss of definition in the jawline and tightness in the neck as they age. This can be caused by a number of factors, including genetics, weight fluctuations, skin laxity, and the natural decline in collagen production. Fine lines start to creep in, elasticity takes a hit, and before you know it, you’re left wondering what happened to your once-firm profile.
The good news? You don’t have to resort to surgery to restore youthful contours. Thanks to modern, non-invasive aesthetic treatments, it’s now possible to lift, tighten, and firm the area under the chin and around the neck. Whether you’re after subtle definition or a more dramatic transformation, there’s a solution to suit your goals.
Why Does the Neck Age So Quickly?
Unlike other areas of the body, the skin on your neck is thinner, has fewer oil glands, and is often neglected in daily skincare routines. As a result, it’s more prone to premature signs of ageing. Combined with the constant movement of the head and external aggressors like sun exposure, the neck is particularly vulnerable to fine lines and sagging. Over time, a build-up of fat under the chin—known as submental fat—can also cause a double chin to form, even in people who are otherwise slim.
Injectable Hyaluronic Acid for Hydration & Lift
Hyaluronic acid is widely known for its ability to retain water—up to 1,000 times its weight! When injected, it delivers a powerful plumping and hydrating effect in targeted areas of the neck or jawline. Fine lines become softer, and the skin gains a visibly firmer, smoother appearance.
Injectable hyaluronic acid can be used in:
-
Skin boosters: These work to improve overall skin texture and hydration, helping to smooth crepey skin.
-
Jawline filler: Strategic placement of filler can enhance definition and support sagging tissues, subtly lifting the neck area.
While results are immediate, ongoing treatments every 6–12 months are typically recommended to maintain the effect.
Polynucleotides: Cellular Repair from Within
A relatively new innovation in aesthetic medicine, polynucleotides are fast becoming a go-to solution for restoring skin health and elasticity. These biostimulating injectables are made from purified fragments of DNA that trigger your body’s natural regeneration processes.
Specifically, when used in the neck and under-chin area, polynucleotides:
-
Improve skin quality and elasticity
-
Stimulate collagen and elastin production
-
Reduce inflammation and oxidative stress
-
Revitalise dull, sagging skin
Unlike hyaluronic acid, polynucleotides don’t simply fill or hydrate—they actually help your skin heal and rebuild itself, offering long-term structural improvement. In essence, it’s deep skin rehab.
Sculptra: Stimulate and Sculpt
If you’re looking for a longer-lasting, collagen-boosting treatment, Sculptra might be your perfect match. Made from poly-L-lactic acid, Sculptra works by stimulating your body’s own collagen production over time, gradually improving volume loss and sagging skin.
When used in the neck and jawline, Sculptra can:
-
Add subtle volume where tissue has thinned
-
Lift and firm the area beneath the chin
-
Improve the overall texture and tightness of the neck
Typically, it’s administered in a series of treatments spaced weeks apart, and offers results that last up to two years. Therefore, it’s an excellent choice for those wanting a gradual, natural-looking transformation.
Other Highly Effective Treatments
While injectables are fantastic, a comprehensive anti-ageing strategy for the neck often combines multiple modalities. Here are some additional treatments worth considering:
Radiofrequency Skin Tightening
Radiofrequency (RF) uses controlled heat to stimulate collagen production and tighten existing collagen fibres. This is a non-invasive option that’s especially effective for mild to moderate sagging and can be used as a preventative treatment.
Popular RF-based treatments include:
These can be used alone or combined with injectables to amplify results.
Ultrasound-Based Lifting (Ultherapy)
Ultherapy uses micro-focused ultrasound to lift and tighten deeper layers of tissue without surgery. It’s a favourite for those looking to combat saggy neck without needles, and results develop gradually over 2–3 months post-treatment.
Fat Dissolving Injections (e.g. Aqualyx or Belkyra)
If your main concern is stubborn fat under the chin, fat-dissolving injections can be a game-changer. These treatments break down and eliminate fat cells in the area, creating a slimmer and more sculpted jawline.
Finding the Right Treatment for Double Chin and Saggy Neck
When it comes to rejuvenating the neck and jawline, there is no one-size-fits-all approach. The ideal treatment (or combination of treatments) will depend on your age, skin quality, anatomy, and aesthetic goals. A personalised consultation with a qualified practitioner is essential to determine what will deliver the best results.
You don’t have to accept a saggy neck or double chin as part of getting older. With today’s advanced aesthetic treatments—from injectable hyaluronic acid and polynucleotides to Sculptra and beyond—you can reclaim definition, firmness, and youthful elasticity with minimal downtime.
