What Are Fat Dissolving Injections?

​

Fat dissolving injections are a non-invasive aesthetic treatment designed to reduce localised fat deposits that are resistant to diet and exercise. These injectable solutions work by breaking down the fat cell membranes, which are then naturally flushed out by the body’s lymphatic system over time.

​

At Ultra Aesthetics, we offer two leading fat dissolving products: Aqualyx and DESO, both CE-marked for use in the UK and performed only by qualified professionals.

​

Treatment Areas

Fat dissolving injections can be used on various areas of the body, including:

• Double chin (submental area)

• Upper and lower abdomen

• Love handles (flanks)

• Inner thighs

• Outer thighs

• Upper arms

• Bra fat

• Knees

• Back fat

​

Aqualyx

Aqualyx is one of the most recognised fat dissolving treatments in the UK. It is a biocompatible, water-based gel that contains deoxycholic acid – a compound naturally found in the body that helps break down dietary fat. Aqualyx works gradually over several weeks, with optimal results typically seen after a course of 2–6 sessions depending on the area treated.

Key Features:

• Ideal for small to moderate fat pockets

• Well-established safety profile

• Gradual fat reduction over 4–6 weeks

• Minimal downtime

​

DESO (Desoxycholic Acid)

DESO is a newer, more concentrated fat dissolving injectable that contains synthetic desoxycholic acid, also used in medical-grade fat reduction treatments. DESO is available in two targeted formulations:

• DESO Face – for smaller, delicate areas such as the chin

• DESO Body – for larger, more stubborn fat areas

Key Features:

• Higher potency than Aqualyx

• Fewer sessions required for some clients

• May work faster due to stronger formulation

• More suitable for resistant fat deposits
