Fat Dissolving Injections in Doncaster

Submental fat — the pad of fat that sits beneath the chin and in front of the neck — is among the most common and most self-consciousness-inducing facial concerns that patients bring to Elements Medical. It creates the appearance of a double chin that can make the jawline look less defined, the neck appear shorter and the overall facial profile heavier than patients feel it should be. The frustrating reality for many people is that no amount of dietary change or exercise specifically reduces this area — submental fat is stubborn, localised, and largely resistant to the lifestyle approaches that reduce fat elsewhere in the body.

Fat dissolving injections use a lipolytic agent — in this case DesoFace, a deoxycholic acid-based injection formulated specifically for facial fat reduction — to directly target and destroy fat cells in the treatment area. Deoxycholic acid is a naturally occurring bile acid that the body uses to break down dietary fat; when injected into a localised fat deposit, it disrupts the cell membranes of the fat cells at that location, causing them to lyse and release their contents. The body then processes and disposes of the cellular debris through its lymphatic system over the weeks following treatment.

Because the fat cells themselves are destroyed rather than simply reduced in size, the results are long-lasting — treated fat cells do not regenerate. However, maintaining weight is important, as significant weight gain can cause remaining fat cells in the area to enlarge, partially restoring the appearance that treatment has improved.

At Elements Medical we offer fat dissolving injections as part of a comprehensive facial contouring range, and for patients who want to maximise their chin and jawline results, we offer a combination package with RF microneedling skin tightening — which firms and tightens the overlying skin as the fat volume reduces.

Our Doncaster clinic is on Thorne Road with on-site parking, and we welcome patients from across South Yorkshire including Rotherham, Wakefield, Sheffield, Leeds and Barnsley.

What Are Fat Dissolving Injections and How Do They Work?

Fat dissolving injections — also called intralipotherapy — use a lipolytic agent injected directly into a localised fat deposit to destroy the fat cells at that location. At Elements Medical, the product used is DesoFace: a formulation specifically developed for facial fat reduction, containing deoxycholic acid as its active lipolytic component.

How deoxycholic acid works: Deoxycholic acid is a bile salt naturally produced by the body and used in the digestive process to emulsify dietary fats. When injected into adipose (fat) tissue, it acts as a cytolytic agent — it disrupts and destroys the phospholipid cell membrane of adipocytes (fat cells) at the injection site. The contents of the lysed fat cells are released into the surrounding tissue and subsequently processed and removed by the body’s lymphatic and immune systems over the two to four weeks following treatment.

Why the results are long-lasting: Adipocytes — fat cells — do not regenerate in the same location once destroyed. The fat cells targeted by DesoFace are permanently eliminated, meaning the reduction in fat volume at the treatment site is lasting. Consequently, results from a completed course of treatment are maintained indefinitely provided weight remains stable.

What happens in the treatment area post-injection: The destruction of fat cells triggers a localised inflammatory response in the days following treatment — this is the mechanism by which the body clears the cellular debris, and it manifests as swelling, firmness and temporary tenderness in the chin area. This response is normal and expected, and resolves progressively over one to two weeks as the lymphatic system clears the treated tissue.

The clinical evidence for deoxycholic acid in the non-surgical reduction of submental fat is supported by peer-reviewed research. British Journal of Dermatology — lipolytic injections and submental fat 

How Is Fat Dissolving Treatment Performed? Step by Step

Before treatment:

• A full consultation is held to assess the submental fat layer, confirm your suitability and discuss realistic outcomes; the number of sessions required is estimated based on the thickness of the fat deposit
• Avoid blood-thinning supplements and alcohol for 24 hours before treatment to minimise bruising risk
• No topical anaesthetic is required, though a cooling device or ice may be used to improve comfort

During treatment:

• The chin and submental area is thoroughly cleansed and the injection grid mapped
• DesoFace is administered as a series of small, precise injections in a grid pattern across the submental fat area
• The number of injection points depends on the area being treated — typically 20 to 30 injection points per session
• A mild burning or stinging sensation during the injection is normal and resolves quickly
• The procedure takes 10 to 20 minutes

After treatment:

• Swelling, redness, firmness and tenderness in the treated area are normal and expected — they reflect the body’s inflammatory response to the lysed fat cells
• Swelling is often most pronounced in the first 48 to 72 hours and then progressively subsides over one to two weeks
• Avoid touching or massaging the treated area for 24 hours
• Avoid heat, vigorous exercise and alcohol for 24 to 48 hours post-treatment
• Results become visible from approximately four weeks after the final session as the body fully processes and disposes of the treated fat cells

The Purposes of Fat Dissolving Injections

1. Restoring a Slimmer, More Defined Chin and Jawline Profile by Permanently Reducing Submental Fat

The primary purpose of fat dissolving injections is to permanently reduce the volume of the localised submental fat deposit that creates the appearance of a double chin, restoring a slimmer and more defined chin and jawline profile. Because the treated fat cells are destroyed and do not regenerate, the improvement in the chin profile is long-lasting and does not require ongoing treatment to maintain — provided weight remains stable. For patients who have carried a double chin throughout their adult life regardless of their weight, the change in facial profile that a completed course of fat dissolving produces is often among the most significant and personally meaningful cosmetic improvements they have experienced.

2. Maintaining the Result Through Weight Stability and Optional Skin Tightening Support

The fat cells destroyed by DesoFace treatment do not return, and consequently the reduction in submental fat volume is maintained long-term. However, two factors influence how well the result holds over time. First, significant weight gain can cause the remaining fat cells in the area to enlarge, partially restoring the submental fullness. Second, as the fat volume reduces, the overlying skin needs to adapt — and for patients with lower skin elasticity, some degree of skin laxity may develop in the chin area. Combining fat dissolving with a course of RF microneedling skin tightening addresses this proactively by stimulating collagen production and firming the overlying skin as the fat volume reduces.

3. Protecting Confidence and Psychological Wellbeing by Addressing a Persistent and Resistant Cosmetic Concern

A double chin is a concern that many people feel is disproportionate to their overall body composition — they are not overweight, they eat well, they exercise, and yet this specific feature persists and affects how they feel about their profile in photographs and in everyday life. The fact that it cannot be addressed through lifestyle measures makes it particularly frustrating. Providing an effective, non-surgical, clinically established route to reducing it directly — and seeing the change in profile that results — produces a meaningful and lasting improvement in confidence and how patients feel about their overall appearance.

Proven Benefits of Fat Dissolving Injections

Permanently destroys targeted fat cells DesoFace’s active lipolytic agent destroys the fat cell membranes in the treatment area — the treated fat cells do not regenerate, making the reduction in submental fat volume long-lasting provided weight remains stable.

Non-surgical alternative to liposuction Fat dissolving injections produce a clinically meaningful reduction in localised submental fat without surgery, general anaesthetic or the recovery period associated with surgical liposuction.

Creates a visibly slimmer, more defined chin and jawline profile The reduction in submental fat volume produces a noticeable improvement in the chin and jawline profile — less fullness beneath the chin, a more defined jaw angle and a generally slimmer, more contoured lower face appearance.

Minimal downtime — normal activities resume immediately Most patients return to normal daily activities immediately after treatment. The swelling and tenderness that follow are manageable and do not prevent normal function, though more visibly significant swelling in the first few days may require social consideration.

Well-tolerated with no general anaesthetic required The procedure requires no general anaesthetic and is performed under local cooling for comfort. The injection sensation is mild and brief.

Combines with RF microneedling for maximised results The combination of fat dissolving injections and RF microneedling skin tightening addresses both the fat volume and the overlying skin quality simultaneously — producing a tighter, firmer and more comprehensively contoured chin and neck result than fat dissolving alone.

Complementary to facial contouring treatments for a complete lower face result Fat dissolving combines effectively with jawline filler and chin filler for patients who want to both reduce submental fat and add structural definition and projection to the jawline and chin, producing a more complete lower face contouring result.

Who Is a Suitable Candidate for Fat Dissolving Injections?

Fat dissolving injections are most appropriate for patients who have a clearly defined, localised pocket of submental fat beneath the chin — a double chin — that persists regardless of diet and exercise and is not proportionate to their overall body weight or composition.

The treatment is not appropriate for patients with generalised obesity or as a weight loss solution — it is a targeted body contouring treatment for a specific, localised fat deposit. Patients who are significantly overweight would be better served by addressing overall weight management first, as the submental fat deposit in this context is part of a broader fat distribution pattern rather than an isolated cosmetic concern.

The treatment is also not appropriate for patients with active skin infections, inflammatory skin conditions or keloid scarring in the treatment area, or for patients who are pregnant or breastfeeding. All contraindications are assessed at consultation.

Fat Dissolving Injections vs Jawline Filler — Different Solutions for Different Concerns

Jawline filler and fat dissolving injections both improve the chin and jawline area but address fundamentally different concerns.

Jawline filler adds structural definition and projection to the jawline — it is the appropriate treatment when the concern is a lack of definition, a recessed chin-to-jaw profile or an absent jaw angle rather than submental fat.

Fat dissolving addresses the excess fat beneath the chin that creates the double chin appearance. It reduces volume rather than adding it.

For many patients, the most effective lower face contouring result comes from addressing both concerns: fat dissolving to reduce submental fat volume, and filler to define the jaw and chin structure. The two treatments work in complementary directions — one removing what should not be there, the other adding definition where it is needed. Your practitioner will assess the appropriate approach for your specific anatomy at consultation.

Fat Dissolving Injections vs Jawline Slimming — What Is the Difference?

Jawline slimming uses botulinum toxin to reduce the width of the lower face by shrinking the masseter muscles — it addresses the squareness or width of the jaw caused by prominent masseter muscle bulk.

Fat dissolving addresses the submental fat beneath the chin — a completely different tissue in a different location. The two treatments are not alternatives to each other; they address different anatomical concerns and may both be relevant for a patient who has both prominent masseters and a double chin.

Your practitioner will assess your specific anatomy and the relative contribution of different factors to your lower face appearance at consultation, and recommend the most appropriate single or combined treatment plan.
