Fat-dissolving injections have been part of the aesthetic treatment menu for many years, and yet, it could be argued, they are one of the most misunderstood procedures out there.
Designed to reduce stubborn pockets of fat, fat-dissolving injections can produce good outcomes in appropriately selected patients and areas, however, they also have a distinct risk profile that differs from other injectable procedures.
Poor patient selection, inadequate training, incorrect injection technique and the use of unverified products can all increase the likelihood of complications and, ultimately, complaints or claims.
As such, it is important to understand where the risks lie and how practitioners can help protect both their patients and their business.
Fat-dissolving injections, otherwise known as injectable lipolysis, involve injecting compounds such as deoxycholic acid or phosphatidylcholine-based solutions into localised pockets of fat. The treatment works by disrupting fat cells, allowing the body to gradually remove them through its natural inflammatory and metabolic processes.
You may have heard injectable lipolysis referred to by various brand names, including Aqualyx, DesoBody, DesoFace, Celluform and Kybella. While these products all fall within the fat-dissolving treatment category, they differ in their formulation, indications and regulatory status. More recently, products such as Lemon Bottle have attracted significant attention on social media and within the aesthetics industry, prompting debate around their composition, evidence base and clinical effectiveness. Whatever product you choose, it's important to understand exactly what it contains, follow the manufacturer's guidance, and source it through authorised suppliers.
Unlike prescription weight-loss medicines, injectable lipolysis is not a treatment for obesity or general weight reduction. Instead, it is designed for patients who have small, localised areas of stubborn fat that have not responded to diet and exercise.
Common treatment areas include the submental area (double chin), abdomen, flanks, thighs and other carefully selected body areas.
As consultant surgeon and international trainer Dr Arturo Almeida explains, one of the biggest misconceptions is believing these treatments are designed for weight loss.
"This is not a weight-loss treatment by any means. The right patient is someone with a normal BMI who has localised pockets of fat despite maintaining a healthy diet and exercise programme", he says.
Like any injectable treatment, complications can occur.
Many adverse events are mild and settle with appropriate aftercare, but more significant complications are well documented within the medical literature.
These include:
Importantly, many of these complications are technique-dependent.
Dr Almeida believes the treatment itself is often misunderstood rather than inherently unsafe. In his experience, complications frequently arise because practitioners have received insufficient training or have learned incorrect injection techniques.
"The products need to be used in the right patient, the right area and with the right technique," he explains, describing these as the three principles underpinning safe injectable lipolysis.
Understanding anatomy is equally important. While injectable lipolysis may be suitable for certain areas, others carry unacceptable levels of risk. Facial fat compartments beyond the submental area, for example, present a greater risk of nerve injury, while areas such as the ankles should not be treated because the apparent fullness is often related to underlying anatomical structures rather than excess fat.
Another growing concern is the increasing availability of fat-dissolving products sold online.
Some products marketed as fat-dissolving injections are not licensed or appropriately regulated for use in the UK, while others may be counterfeit or sourced outside authorised distribution channels.
Practitioners may assume that buying a familiar-looking product online offers the same level of reassurance as purchasing through an authorised supplier, but this is not always the case.
Dr Almeida also highlights how viral marketing and social media trends have influenced product choices, with some practitioners adopting products because patients requested them rather than because there was robust clinical evidence supporting their use.
Hamilton Fraser has written previously about the risks associated with grey-market and counterfeit products. Purchasing only through reputable, authorised suppliers helps reduce both patient safety risks and professional liability.
Many complaints begin long before treatment takes place.
A thorough consultation allows practitioners to establish whether injectable lipolysis is appropriate while helping patients understand what the treatment can realistically achieve.
This should include:
Dr Almeida believes consultation is often the most undervalued part of aesthetic practice.
Rather than viewing consultation as time away from treatment, he argues that it is where expectations are managed, misconceptions corrected and trust established. Practitioners who spend time educating patients are often better placed to prevent dissatisfaction later in the treatment journey.

Injectable lipolysis carries specific insurance considerations that practitioners should understand before introducing it into practice.
Firstly, don't assume that because you are insured for injectable treatments, fat-dissolving procedures are automatically included. Treatments must be specifically listed on your policy schedule.
Secondly, using products that are unlicensed, counterfeit or obtained through unauthorised distribution channels could affect your insurance cover if a claim arises.
Claims relating to fat-dissolving treatments do occur, particularly where there are allegations of poor patient selection, inadequate consent, inappropriate treatment planning or complications following incorrect injection technique.
Before offering injectable lipolysis, make sure your insurer knows exactly which treatments you perform and that your policy schedule reflects this.
Hamilton Fraser provides cover for a wide range of fat-dissolving treatments, subject to policy terms and conditions. If you're unsure whether a treatment is covered, speak to the team before introducing it into your clinic.
Fat-dissolving treatments can be a valuable addition to an aesthetic practice when performed appropriately. Reducing risk comes down to consistent clinical standards:
If you are offering or considering offering injection lipolysis in your practice, combining high standards of clinical practice and training with robust consultation, documentation, and insurance can help reduce the likelihood of complaints and claims and support you if any do arise.
