How Effective Are Fat-Dissolving Injections?

Sometimes, no matter how much you eat right or exercise, you can struggle to shift fatty deposits in stubborn areas of the body. For some, it’s the little belly pooch, while for others, it might be a double chin or back fat. Several areas of the body can keep hold of stubborn fat through no fault of our own, and this is completely normal and nothing to be ashamed of. However, many people feel that their confidence would sky-rocket if they were to find an effective way to eliminate these fat pockets — so what are the options?

Surgery is an obvious choice, but it can be expensive and scary. Invasive treatment isn’t the right fit for everyone, and going under the knife is something most would feel apprehensive about. For many people, liposuction or cosmetic surgery, in general, is not an option they want to explore, in which case they may consider non-surgical weight loss treatments as a low-risk alternative.

One such weight loss treatment is injection lipolysis, also known as fat-dissolving injections. At Harley Street MD, our expert clinicians use Aqualyx® weight loss injections to reduce the appearance of fatty areas, helping patients achieve the body shape they’ve been striving for. This treatment involves a quick, minimally invasive procedure and will provide results within approximately eight weeks. If you’re curious about how effective fat-dissolving injections are, read on to find out more about them and what you can expect from this type of treatment.

What Is a Fat-Dissolving Injection?

Put quite simply, it’s an injection administered to problem areas in the body that works by dissolving stubborn fat. Fat-dissolving injections are designed to target localised fat deposits and aren’t a substitute for losing weight. This treatment is intended to complement a healthy lifestyle, which means patients should aim to maintain a balanced diet and exercise routine alongside injections.

Aqualyx is one of the leading fat removal injections and has had great success since it first launched in the UK in 2013. This treatment is safe for use, and we’ve seen our clients experience fantastic results with it.

Aqualyx provides targeted results without the need for surgery or liposuction. The procedure requires minimal downtime, too, so you can go back to work the same day as receiving treatment. It’s not uncomfortable or invasive, which means patients experience minimal worry or stress before the procedure. It can be used to treat the following areas:

Tummy bulges 

Inner and outer thighs




Double chin

Back fat

Love handles

Buffalo hump (behind the neck)

Chest fat


Upper arms



How Does Aqualyx® work?

The main component of Aqualyx® is Deoxycholic acid (DC). This is a secondary bile acid that is found naturally in the body. When Deoxycholic acid is injected into the subcutaneous layer of fat, it disrupts the fat cells and causes them to dissolve permanently. The fat cells will then be naturally released and drained away by your lymphatic system, which is why we always recommend drinking plenty of water after your treatment and avoiding alcohol too. 

Your comfort is always a priority, and you won’t feel too much discomfort when receiving fat-dissolving injections. An anaesthetic agent is added into the Aqualyx solution to help relieve any discomfort, and our consultants will also use topical numbing cream on your skin before injection.

Am I a Suitable Candidate for Fat-Dissolving Injections?

If you’ve been questioning, “How effective are fat-dissolving injections?”, the answer is that it depends on how suitable a candidate you are for this type of treatment. Injection lipolysis may be a good fit for you if you’re struggling to achieve your desired weight despite having made healthy lifestyle changes — for example, if you’ve tried changing your diet and exercising more but are still struggling to get rid of localised pockets of fat.

It’s essential that you don’t see fat-dissolving injections as simply a quick and easy way to lose weight, as your own efforts will be required alongside treatment. If you’re close to your ideal body weight but need an extra push to achieve the look you want, Aqualyx is an excellent option. If you’re severely overweight, a different non-surgical weight loss procedure such as a medical weight loss treatment may be the right fit for you.

How Long until Fat-Dissolving Injections Show Results?

Fat-dissolving injections are repeated every three to four weeks until your desired look has been achieved, and your consultant will advise how many sessions they would recommend for you personally. You won’t see the results immediately after each procedure, as your body has to naturally drain away the dissolved fat deposits as part of its normal process.

With Aqualyx, patients can typically expect to see results around eight weeks after their first treatment, as this is how long the body’s natural draining process takes. Most people will need at least two treatments to see the results they want, but this will also depend on other factors, such as the lifestyle changes you make to complement the procedure.

Are Fat-Dissolving Injections Safe?

Aqualyx is considered a safe form of fat-removal treatment and is licensed for use in the UK. It is approved by the Medicines and Healthcare products Regulatory Agency (MHRA). Minimal side effects have been reported globally since the introduction of Aqualyx, but patients may notice minor skin irritation, bruising and swelling in the injection site, which will ease within a few days. This procedure requires little to no downtime, and you can go about your day as usual following treatment.

How Much Fat Can Be Removed with Fat-Dissolving Injections?

The amount of fat dissolved may vary depending on the area injections are administered, how many sessions you take, and how your body responds to the treatment. Enhanced results can be encouraged by drinking lots of water to help with lymphatic drainage and exercising alongside treatment.

We always recommend talking things through with your consultant after booking, so you have a clear idea of what to expect from your personalised treatment plan. For example, with some clients, we may also recommend considering medical slimming options such as Saxenda medical weight loss injections, Orlistat tablets or appetite suppressants. These can often provide more impactful results and accentuate the outcome of fat-dissolving injections.
