Aqualyx Under the Chin: What to Expect Before and After
Fat under the chin is one of the most commonly treated areas with Aqualyx — here's a clear, honest guide to the process.
20 December 2026 · 4 min read

Aqualyx under the chin targets a small, stubborn area of fat beneath the jawline that hasn't responded to diet or exercise. It's one of the most common areas for this treatment, typically delivered over two to three sessions with results building gradually.
Why the chin is a common treatment area
Fat under the chin can be stubborn regardless of overall body weight or fitness, which is why it's one of the most frequently requested areas for this treatment.
Before treatment
A consultation confirms whether this is the right treatment for your specific concern — for some people, the underlying issue is skin laxity rather than fat, which Aqualyx won't address, so an honest assessment matters here.
During and immediately after
The injections themselves are relatively quick. Some swelling under the chin is common afterward and typically settles within one to two weeks.
What results look like over time
Gradual reduction in the treated area as the body processes the fat cells over the weeks following each session — not an immediate change on the day of treatment.
Is it right for you?
Best suited to people with a genuinely localised area of stubborn fat rather than looser or sagging skin — this distinction is exactly what your consultation is for. To understand exactly what Aqualyx is and how it works, read our What Is Aqualyx? explainer.

How many sessions will I need under the chin?
Typically two to three, spaced several weeks apart, confirmed at consultation.
Will there be visible swelling afterward?
Some is common and usually settles within one to two weeks.
What if my concern is loose skin, not fat?
This is worth raising at your consultation — Aqualyx addresses fat, not skin laxity, and a different approach may be more appropriate.
