EndoDefine vs Fat Dissolving Injections for a Double Chin: Which Is Right for You in Surrey?

EndoDefine vs Fat Dissolving Injections for a Double Chin: Which Is Right for You in Surrey?

If you are bothered by fullness under the chin, a soft jawline, or heaviness through the lower face, you are certainly not alone. Many patients come to see me at Revital Lab in Esher because they feel their face has started to look less defined, especially from the side profile or in photographs.

One of the most common questions I’m asked is: "Do I need fat dissolving injections, or would EndoDefine be better?"

It’s a very sensible question, because both treatments can be used around the chin and jawline area, but they do quite different things. The best option depends on what is actually causing the fullness: fat, skin laxity, loss of definition, or a combination of all three.

At our doctor-led clinic in Esher, Surrey, we always start with a consultation because treating a double chin without understanding the cause can lead to disappointing results. For some patients, fat dissolving injections may be suitable. For others, EndoDefine may give a more structured and tightening effect. In many cases, the issue is not just fat, but lower-face ageing and skin laxity.

Here’s how to understand the difference.

What causes a double chin?

A double chin can happen for several reasons. Some patients naturally carry more fullness under the chin, even when they are slim. Others notice it gradually as they get older.

Common causes include:

Localised fat under the chin
Some people have a small pocket of fat beneath the chin that softens the jawline and affects the side profile.

Skin laxity
As collagen reduces with age, the skin under the chin and well.co.uk] along the jawline can become looser. This can make the lower face look heavier even if there is not much fat.

Loss of jawline definition
The jawline can become less sharp due to ageing, changes in facial volume, soft tissue descent, and reduced skin firmness.

Genetics
Some people are simply more prone to fullness under the chin because of their facial structure.

This is why a proper assessment matters. If the main issue is fat, one approach may be suitable. If the main issue is skin laxity or lower-face heaviness, a different approach may be needed.

What are fat dissolving injections?

Fat dissolving injections are used to treat small, localised pockets of fat. They are injected into the area beneath the chin to help break down fat cells over time.

They may be suitable for patients who have a clear pocket of fat under the chin, good skin quality, and only mild or minimal skin laxity.

The treatment is usually done as a course, rather than a one-off session. Swelling is expected afterwards, and results appear gradually as the body processes the treated fat.

Fat dissolving injections can be useful in the right patient, but they are not a skin tightening treatment. This is very important. If the skin is already loose, reducing fat without addressing the skin may sometimes make the area look softer rather than more defined.

What is EndoDefine?

EndoDefine is a doctor-led, minimally invasive treatment designed to improve definition and tightening in areas such as the lower face, jawline and under-chin region.

It is particularly useful for patients who are noticing:

Unlike fat dissolving injections, EndoDefine is not just about reducing fullness. It can also help with tissue tightening and contouring, which is why it is often more appropriate for patients whose concern is a combination of fat, laxity and lower-face ageing.
