What Is Aqualyx? The Fat-Dissolving Treatment We Use

Aqualyx is an injectable solution used to break down small, stubborn pockets of fat resistant to diet and exercise. At London Skin Bar, Aqualyx is the product behind our Fat Dissolving treatment — most commonly used under the chin.

How it works

Aqualyx is injected directly into the targeted fat deposit, where it breaks down fat cells. The body then naturally processes and clears this over the following weeks — results build gradually rather than immediately.

What it's suited for

Small, localised areas of stubborn fat — commonly the chin and jawline — rather than broader body fat or significant weight loss. It's a targeted treatment, not a weight-loss solution.

What a typical course looks like

Most treatment plans involve two to three sessions, spaced several weeks apart, with results developing gradually as the body processes the treated area between sessions.

What to expect physically

Some swelling in the treated area is common in the days after treatment and typically settles within a week or two, though this varies by individual. If you're still deciding, our guide on whether fat dissolving is right for you covers the full picture.
