Now that summer is coming, you might be wondering if fat-dissolving injections are safe to use to help you lose that last bit of winter padding. The fat removal treatments we offer at our London clinic can help you get rid of those stubborn pockets of fat that are resistant to exercise or be used to refine and contour places like the jawline and hips. Non-surgical fat removal treatments like Aqualyx injection lipolysis are becoming more popular than their surgical counterparts, such as liposuction, for several reasons. They are a safe, low-risk form of treatment.

If you have any questions about non-surgical treatments, you can book a no-obligation consultation and speak to our expert team — we’d be happy to help and discuss your treatment options.

What Is Aqualyx?

Aqualyx is a revolutionary non-surgical product that can dissolve localised fat. Made from Deoxycholic Acid (DC) and plant compounds, it liquefies fat cells when injected into the skin. Aqualyx is a safe and effective fat-dissolving injection that destroys fat cells, which are then naturally excreted by the lymphatic system.

Renowned aesthetic surgeon Professor Pasquale Motolese developed the Aqualyx injection in 2004, and it launched globally in 2009. Aqualyx has been used in the UK since December 2012. Aqualyx injections are used safely by thousands of people worldwide

Why Get Weight Loss Injections?

There are areas of the body and face that do not decrease or tone up even through dieting and regular exercise. Our experience is that we can shift this stubborn fat when all else fails with this new technology — fat removal injections. Common areas our patients want to transform are under the chin (the jowls), around the hips (the muffin top), under the upper arms (bingo wings) and the stomach, hips, chest, inner and outer thighs, knees and ankles. Both men and women come to our clinic for this treatment because of its effectiveness.

While fat removal injections are not a great option for larger areas of unwanted fat, they are perfect for people who are at a healthy weight but have a little extra in an isolated area. If you want to remove larger amounts of fat or want to lose a significant amount of weight, non-surgical fat removal treatments are not the best choice. As with any cosmetic weight-loss procedure, it isn’t a substitute for a healthy diet and lifestyle. Removing specific fat cells will be permanent, but maintaining reduced fat cells after treatment is down to you. We can’t work miracles if you don’t do the work needed to maintain your treatment.

Are Fat Removal Treatments Like Aqualyx Safe?

The Aqualyx treatment does not require surgery, which alone makes it safer than procedures involving going under the knife and staying in the hospital. We want everyone to know that surgery isn’t your only option now that non-surgical treatments can be as effective. Surgical treatments like liposuction carry a much greater risk of infection, require more pre and post-treatment requirements and have more extended downtime. Aqualyx is the alternative to invasive liposuction and is available near you at a much lower cost.  

The side effects of fat loss injections are mild. You may experience some pain, light bruising or swelling around the injection area for a few days after treatment. This treatment is not suitable for certain clients, such as pregnant or lactating women or those with certain health conditions like diabetes, liver or kidney disease, or skin issues. Please discuss with your registered clinician if Aqualyx is right for you. 

If you decide to have fat-dissolving injections, choose a reputable clinic. There have been reports of people selling fake products marketed as Aqualyx. It’s also important to note that clinics do not have to be specially licensed to offer fat removal treatments, so you’ll want to receive the procedure from a licensed medical professional.

Frequently Asked Questions about Fat-Dissolving Injections

Do Fat-Melting Treatments Really Work?

Non-surgical weight loss treatments aren’t a miracle worker, but they can help you achieve a slimmer and more contoured physique. As long as treatment is administered alongside healthy lifestyle changes, results can be significant and long-lasting.

How Long Does It Take to See Results?

It may take a few treatments to see results. The procedure is repeated every three to four weeks until the desired results are achieved, with an expert consultant advising how many sessions they would recommend for each patient. Results aren’t immediate after each treatment — swelling may take a few weeks to subside, and it typically takes three to eight weeks for fat deposits to become noticeably reduced.

How Often Will I Need Treatment?

How many rounds of treatment you’ll need varies between individuals and the volume of targeted fat deposits. It’s typical for patients to require at least two treatments to achieve their desired look. On average, two to five sessions of Aqualyx treatment are necessary, with injections being administered every three to four weeks.

What Are Fat-Dissolving Injections Made From?

Aqualyx contains the following naturally occurring ingredients:

Deoxycholic acid

Buffering chemicals

Sodium chloride

Red microalgae sugars

Other sugars


Are There Any Risks Associated with Injection Lipolysis?

Weight loss injections are a low-risk alternative to surgical liposuction. There is a risk of redness, tenderness, bruising or swelling at the injection site, but this should subside within a few days. You can minimise risk by ensuring that a qualified practitioner provides treatment.

Do Fat-Dissolving Injections Hurt?

As with any treatment that involves needles, injections may cause slight pain or discomfort. However, your practitioner will numb the area with a topical cream before the procedure to ensure that pain is minimal.

Weight loss injections are not suitable for:

Pregnant or breastfeeding patients
