What Causes a Double Chin and How to Treat It Without Surgery

A double chin can be one of the most frustrating facial concerns to deal with. You might be otherwise slim, look after yourself, and still notice fullness or softness under the chin that doesn’t seem to change. It’s something we see often at Skin Studio , and it’s also one of the areas people feel most self‑conscious about.

Many assume surgery is the only real solution. Thankfully, that’s no longer the case. Today, doctor‑led, non‑surgical treatments can address both fat under the chin and loss of skin firmness, depending on what’s actually causing the issue.

‍

What Actually Causes a Double Chin?

A double chin isn’t always about weight. In fact, many people with a healthy body weight still experience fat or laxity under the chin.

Common causes include:

• Genetics - some people are simply predisposed to store fat in this area
• Ageing - reduced collagen and elastin can cause the skin to loosen and sag
• Fat accumulation - even a small amount of fat can soften the jawline
• Posture and muscle tone - prolonged downward head posture can contribute over time

Often, it’s a combination of fat and reduced skin quality rather than one single factor.

Why Weight Loss Doesn’t Always Fix a Double Chin

General weight loss can help overall body fat, but it doesn’t allow for targeted fat reduction. Facial fat behaves differently to fat elsewhere in the body, and the area under the chin is particularly stubborn.

This is why people can lose weight and still feel unhappy with their jawline. When fat is localised, it often needs a localised solution.

Meso Lipo: Targeted Fat‑Dissolving Injections

For chin fat specifically, Meso Lipo is one of the most effective non‑surgical options available.

Meso Lipo is an injectable treatment designed to break down fat cells in targeted areas. Once the fat cells are disrupted, the body gradually processes and removes them over time.

At Skin Studio, Meso Lipo is:

• Doctor‑administered for safety and precision
• Customised to your facial structure and level of fullness
• Non‑surgical, with no incisions or general anaesthetic
• Gradual, creating a natural reduction rather than an abrupt change

Most clients require a short course of treatments, typically spaced a few weeks apart. Mild swelling or tenderness is common for a few days, but downtime is minimal.

What If It’s Sagging Skin, Not Fat?

This is an important distinction.

Not all “double chins” are caused by fat. In some cases, the issue is skin laxity rather than fullness - especially as collagen levels decline with age.

When sagging skin is the main concern, skin boosters can be highly effective.

Treatments such as Nucleofill or Rejuran work within the skin to:

• Stimulate collagen and elastin
• Improve firmness and elasticity
• Strengthen and hydrate thinning skin
• Support overall tissue quality under the chin and along the jawline

These treatments don’t remove fat, but they can significantly improve the appearance of looseness and help restore definition. In many cases, skin boosters are combined with Meso Lipo to address both fat and skin quality for a more refined result.

‍

Are There Other Non‑Surgical Options?

Depending on your anatomy and goals, additional treatments may be considered. Subtle jawline contouring or structural support can sometimes enhance the overall outcome, but this is assessed carefully on an individual basis.

At Skin Studio, we don’t take a one‑size‑fits‑all approach. The right treatment plan depends on whether the issue is fat, skin laxity, or a combination of both.

‍

Is This the Right Treatment for You?

You may be a good candidate if:

• You have mild to moderate fullness under the chin
• You notice sagging or softening along the jawline
• You want a non‑surgical solution with natural results
• You understand that results are gradual, not instant

If you’re unsure what’s causing your concern, a professional assessment makes all the difference.

Thinking About Treating a Double Chin in Bali?

A double chin doesn’t need surgery to improve - but it does need the right diagnosis.

Book a free facial assessment with one of Skin Studio’s aesthetic doctors to understand whether Meso Lipo, skin boosters, or a combination approach is best for you. The goal isn’t to change your face - it’s to restore definition in a way that still looks like you.
