How Long Do Fat Dissolving Injections Take to Work?
If you’ve ever struggled with stubborn fat pockets that don’t shift with diet or exercise, you’re not alone. At Alina Budonna Aesthetic Clinic in Knightsbridge, London, many of our patients ask the same question: “How long will it take before I see results from fat dissolving injections?” The short answer: most clients start noticing results within 3–4 weeks, with the most visible improvements appearing after 6–8 weeks. But the full picture depends on several factors, including the area treated, the number of sessions, and your body’s natural response. In this article, we’ll explain everything you need to know before starting your fat-dissolving journey.

What Are Fat Dissolving Injections?
Fat dissolving injections, also known as Aqualyx® or DesoBody treatments, are non-surgical procedures designed to target stubborn fat cells.
They work by breaking down fat cell membranes.
The body then naturally flushes out these fat cells over time.
Popular areas treated include:
Double chin
Arms (“bingo wings”
Stomach
Hips and thighs
Back (“bra bulge”)
Unlike liposuction, there’s no surgery, no general anaesthetic, and minimal downtime.
When Do You Start Seeing Results?
This is the question every client wants answered — and the reality is that results are not instant.
3–4 weeks: Some patients notice early changes as swelling settles.
6–8 weeks: The majority of results become visible.
12 weeks: Best results are usually seen around the 3-month mark.
Pro tip: Patience is key. The treatment relies on your body’s natural elimination process, so gradual improvements are expected.
How Many Sessions Are Needed?
For long-lasting results, most clients require a course of 2–4 sessions.
Small areas (e.g. chin) may only need 1–2 sessions.
Larger areas (e.g. stomach, thighs) may need 3–4 sessions.
Sessions are spaced 4–6 weeks apart to allow the body to process the treated fat cells.
At Alina Budonna Aesthetic Clinic in Knightsbridge, your personalised consultation will include a full treatment plan tailored to your goals.
What to Expect After Treatment
Fat dissolving injections are generally well-tolerated, but it’s important to know what happens after each session.
Swelling, redness, or tenderness for 2–5 days.
Mild bruising may occur but settles quickly.
No downtime, you can return to work or normal activities the same day.
Results improve gradually with each session.
Are Fat Dissolving Injections Right for You?
Fat dissolving injections are not a weight-loss solution. Instead, they are ideal if you:
Are close to your ideal weight but struggle with stubborn fat areas.
Want a non-surgical, minimally invasive option.
Prefer natural-looking results that improve over time.
Are committed to maintaining results with a healthy lifestyle.

Q 1: How long do results last?

Most patients report mild discomfort. Numbing options are available for added comfort.
Q 3: Can fat return?
Treated fat cells are gone for good, but remaining fat cells can enlarge with weight gain.

No, you can return to daily activities immediately. Some swelling and tenderness are normal for a few days.
