Fat dissolving injections: how do they work?

Many people struggle with stubborn pockets of fat that seem resistant to diet and exercise. In the past, the only options for reducing these areas were invasive procedures like liposuction. However, in recent years, fat dissolving injections have become a popular alternative for those seeking a less invasive approach.

But how do these injections work, and are they safe? In this article, we'll explore the cellular mechanisms behind fat dissolving injections, their composition, safety, and the frequency

of treatment required.

What Are Fat Dissolving Injections?

Fat dissolving injections, also known as lipolytic injections, are a non-surgical cosmetic treatment designed to reduce localised areas of fat. The injections contain a synthetic form of deoxycholic acid, a bile acid that is naturally produced by the body to aid in the digestion of dietary fats.

When injected into the targeted area, the deoxycholic acid works by breaking down the membranes of fat cells, causing them to release their contents into the bloodstream. The released fat is then metabolised and eliminated by the liver and other organs over time.

Composition of Fat Dissolving Injections

The active ingredient in fat dissolving injections is a synthetic form of deoxycholic acid. This synthetic form is created in a laboratory and is chemically identical to the naturally occurring form in the body. It is manufactured under strict quality control standards to ensure its safety and effectiveness.

The injections are typically administered using a fine needle to target specific areas of fat, such as the chin, jowls, thighs, hips, and abdomen. The number of injections required depends on the size of the treatment area and the amount of fat being targeted.

Safety of Fat Dissolving Injections

Fat dissolving injections are generally considered safe when a trained and licensed practitioner. The synthetic deoxycholic acid used in the injections is biocompatible, meaning that it is well-tolerated by the body and does not trigger an immune response.

However, as with any medical procedure, there are risks and potential side effects. Some of the most common side effects include swelling, bruising, redness, and mild discomfort at the injection site. These side effects typically subside within a few days to a week after treatment.

Less common side effects may include numbness and tingling in the treated area.

Frequency of Treatment

The frequency of treatment required for fat dissolving injections depends on several factors, including the size of the treatment area and the amount of fat being targeted. Most patients require a series of injections spaced several weeks apart to achieve optimal results.

The number of injections required also depends on the individual's goals and expectations. Some patients may be satisfied with the results after a single treatment, while others may require multiple sessions to achieve their desired outcome.

It's essential to maintain a healthy lifestyle, including a balanced diet and regular exercise, to maximise the effectiveness and longevity of the treatment. While fat cells are permanently destroyed by the injections, new fat cells can form if the patient gains weight after the procedure.


Fat dissolving injections can be a safe and effective alternative to invasive procedures for reducing localised areas of fat. By breaking down fat cells' membranes and causing them to release their contents into the bloodstream, the injections promote the body's natural metabolism and elimination of fat.
