Non-Surgical Double Chin Treatments
Reduce Stubborn Chin Fat and Tighten Loose Skin at CJA Aesthetics Clinics Hampshire
A double chin can affect people of all ages and body shapes. Even if you are slim, you may still develop fullness beneath the chin due to genetics, ageing, skin laxity or changes in collagen support. For many people, this area is particularly resistant to diet and exercise.
CJA Aesthetics Clinics in Portsmouth, Southampton and Winchester offer a range of advanced non-surgical treatments designed to reduce excess fat, tighten loose skin and improve jawline definition without surgery.
Treatments are carried out following a detailed consultation with registered doctor Dr Chris Airey, who will assess the cause of your double chin and recommend the most appropriate treatment plan for your individual concerns.

What Causes a Double Chin?
A double chin (submental fullness) can develop for several reasons:
- Stubborn localised fat deposits
- Loss of skin elasticity with age
- Weakening of the muscles and connective tissues under the chin
- Genetic predisposition
- Weight gain or fluctuations
- Poor jawline support.
The most effective treatment depends on whether the problem is primarily excess fat, loose skin, or a combination of both. Please book a consultation at a CJA Aesthetics Clinic near you so we can assess your needs and recommend the best course of treatments.


Fat Dissolving Injections for Double Chins
One of the most popular treatments for a double chin is deoxycholic acid fat dissolving injections. As well as improving the appearance of double chins, fat dissolving injections can be used to improve arms (bingo wings), inner and outer thighs, back fat and abdomen fat.
A consultation is essential to determine whether these areas are appropriate for treatment.
Deoxycholic acid is a substance that occurs naturally in the body and helps to break down dietary fat. When a synthetic medical-grade form is injected into the fatty tissue beneath the chin, it destroys fat cells, which are then gradually removed by the body’s natural metabolic processes.
During treatment, a series of small injections is placed into the fatty area beneath the chin. Temporary swelling, redness, tenderness or bruising is normal and usually settles within a few days.
Because the destroyed fat cells cannot regenerate, the results can be permanent, provided a stable weight is maintained. Most clients begin to notice an improvement within 3-4 weeks, with more significant results developing over 8-12 weeks.
A course of 2-4 treatments, spaced approximately 4 weeks apart, is commonly recommended for optimal results.
Laser Jawline Tightening Without Surgery
For patients who have both excess fat and loose skin, Endolift® is one of the most advanced non-surgical options available.
Endolift uses a micro-optical laser fibre inserted just beneath the skin through a tiny entry point. The laser energy:
- Melts small pockets of fat
- Stimulates collagen production
- Tightens and contracts the skin
- Improves jawline definition
- Lifts sagging tissue beneath the chin
This is performed under local anaesthetic and provides an immediate tightening effect. Clients usually see continued improvement for 3-6 months as new collagen forms.
Endolift is often recommended if we feel that fat dissolving injections alone may not provide enough skin tightening.


Tighten & Firm Skin With Radio Frequency Microneedling
Sylfirm X combines radiofrequency energy with ultra-fine microneedling to remodel the deeper layers of the skin. This treatment is ideal for patients whose double chin is associated with loose crepey skin, loss of firmness, early jowl formation, poor skin texture and age-related collagen loss.
The tiny needles create controlled micro-injuries while delivering radio frequency heat into the dermis. This stimulates:
- Collagen production
- Elastin regeneration
- Skin contraction
- Improved firmness and elasticity
- Better contour beneath the jawline
A course of 3 sessions spaced 4-6 weeks apart is usually recommended. Results develop gradually, with the skin continuing to improve for several months after treatment. Sylfirm X is an excellent option for patients who want skin tightening without injectables or surgery.
Spring Thread Lifts for Double Chins
If your main concern is sagging skin or loss of jawline definition, a Spring Thread Lift may be the most effective solution.
Spring Threads are specially designed elastic threads that are placed beneath the skin to:
- Lift sagging tissue
- Support the jawline
- Reduce the appearance of a double chin
- Improve definition between the chin and neck
- Stimulate collagen production around the threads
Spring Thread Lifts give an immediate lifting effect with natural-looking results. There is very little downtime compared with surgical facelifts and clients see continued collagen stimulation for several months afterwards.
This treatment is particularly suitable for patients with skin laxity and early jowling, rather than significant fat accumulation.

FAQs About Double Chin Treatments
What is the best non-surgical treatment for a double chin?
«The best treatment depends on the cause of the problem. Fat dissolving injections are ideal for excess fat, while Endolift®, Sylfirm X or Spring Thread Lifts are often better for loose or sagging skin. Please book a consultation so we can assess your needs and recommend the best treatments for you.
Are fat dissolving injections permanent?
«Yes. The treated fat cells are destroyed and removed by the body, so they cannot regenerate. However, remaining fat cells can still enlarge if significant weight is gained.
How many fat dissolving treatments will I need?
«Most clients require 2-4 sessions, spaced about 4 weeks apart, although this varies depending on the amount of submental fat present.
Is Endolift for double chins painful?
«Endolift is performed under local anaesthetic, so discomfort is usually minimal. You may experience some tenderness or swelling for a few days afterwards.
How long do Endolift results last?
«Results can last several years, particularly when combined with good skincare, sun protection and a stable weight. Collagen production continues to improve for 3-6 months after treatment.
What is the downtime after RF Microneedling?
«Most clients experience mild redness and slight swelling for 24-48 hours. Normal activities can usually be resumed very quickly.
Can Sylfirm X RF Microneedling remove fat under the chin?
«Sylfirm X is primarily a skin tightening and collagen stimulation treatment. It may slightly improve contouring, but it is not designed to remove significant fat deposits.
What are Spring Threads made from?
«Spring Threads are made from biocompatible medical-grade materials designed to safely support and lift the tissues beneath the skin. Threading is a good option if you have skin laxity which is contributing to your double chin but it might be better to combine this with another double chin treatment, depending on your needs.
When will I see results from a Spring Thread Lift?
«You will usually notice an immediate lifting effect, with further improvement developing over the following 2-3 months as collagen forms around the threads.
Can these treatments be combined with other face procedures?
«Yes. Double chin treatments are often combined with anti-wrinkle injections, dermal fillers, skin tightening treatments or medical-grade skincare to create a more balanced and rejuvenated lower face and neck appearance. Please book a consultation at a CJA Aesthetics Clinic - either face-to-face or online via video - so we can chat through the best options for you.
