Fat dissolving injections are one of the most searched cosmetic treatments in the UK, but only one product holds a UK marketing authorisation for cosmetic fat reduction, and its licence covers a single, narrow use. Everything else on the market, including the viral Lemon Bottle brand, sits outside that licensed system and carries different rules and risks. Which category a product falls into matters far more than the name on the box.
What counts as a fat dissolving injection?
'Fat dissolving' is a marketing term, not a single product. In UK clinics it covers at least three different families: deoxycholic acid (the active ingredient in Belkyra), phosphatidylcholine based formulas (often sold as Lipo Lab or similar), and proprietary blends marketed directly to consumers, most notably Lemon Bottle, made by the South Korean company SID Medicos. Each sits in a different place under UK medicines law, and the difference is not cosmetic.
Belkyra: the one product with a UK licence
Belkyra, based on deoxycholic acid, has held UK marketing authorisation since 2021 and is a prescription only medicine, meaning it can only be prescribed by a registered independent prescriber. Its licence covers a single indication: moderate to severe convexity or fullness associated with submental fat, commonly known as a double chin. Using deoxycholic acid on a different part of the body falls outside that licence and becomes off label prescribing, which is legal but requires the prescriber to justify the decision and explain it clearly to the patient.
Why Lemon Bottle and PPC products sit outside that system
In April 2025, the General Pharmaceutical Council (GPhC) warned pharmacies against supplying Lemon Bottle and similar products, describing them as non medicinal, unregulated and unlicensed, and linking them to reported harms including severe bruising, infections, abscesses and, in one case, tissue necrosis. Lemon Bottle holds no MHRA marketing authorisation, no CE mark and no FDA approval. Separately, the Joint Council for Cosmetic Practitioners (JCCP) has told its registrants that the MHRA advises phosphatidylcholine, the active ingredient in products such as Lipo Lab, is not authorised for use in the UK and must not be used for cosmetic purposes at all; JCCP registrants have been instructed to stop using or promoting PPC products for cosmetic procedures.
What to check before booking a fat dissolving treatment
Ask for the exact product name, not just the phrase 'fat dissolving', and ask whether it holds a UK marketing authorisation for the area you want treated. If the answer is a prescription only medicine, confirm the practitioner is a registered independent prescriber and check they appear on a recognised register such as the JCCP's. A reputable clinic will answer these questions directly, and a proper consultation is the right place to discuss whether a particular treatment suits your goals and medical history.
Common questions
- Are fat dissolving injections safe in the UK?
- Safety depends entirely on which product is used and who administers it. Licensed prescription only medicines go through MHRA assessment and are prescribed by a registered independent prescriber, while unlicensed products, including Lemon Bottle, have no such oversight and have been linked to reported harms by the GPhC. Ask about the specific product before assuming any 'fat dissolving' injection is automatically low risk.
- Is Lemon Bottle legal to buy and use in the UK?
- Lemon Bottle is not banned outright, but it holds no MHRA marketing authorisation, no CE mark and no FDA approval, and the GPhC warned pharmacies in April 2025 against supplying it as though it were a regulated medicine. Its status sits in a grey area between cosmetic product and medicine, which is exactly why regulators have raised concerns.
- What is the only fat dissolving injection licensed in the UK?
- Belkyra, based on deoxycholic acid, is the product with UK marketing authorisation for cosmetic fat reduction, and its licence covers only submental fullness, commonly known as a double chin. It has been available in the UK since 2021 as a prescription only medicine. Any other product, or any use outside that specific indication, sits outside the licensed system.
