Why there is confusion around one substance
Deoxycholic acid is a substance produced by the body. It is a natural component of bile that breaks down fats in the digestive tract. The discovery that, at the right concentration and injection site, it can mechanically destroy fat cells opened up an entire branch of aesthetic medicine. The problem begins when the word “deoxycholic” becomes a marketing term added to descriptions of products with very different properties. Some are certified and some are not. Some have clinical research and some do not. Some are manufactured in Europe, while others come from eastern markets. A patient reads “deoxycholic acid” and assumes everything is the same. The difference can be substantial.
Six myths — one by one
Myth 1: “Aqualyx and other deoxycholic acid products are the same substance, just packaged differently.” This is the most costly oversimplification you can make. Aqualyx is a product with a precisely defined composition, concentration and pH. It is manufactured by an Italian producer, Marllor Biomedical, and has clinical documentation and CE certification. A “deoxycholic acid product” may mean anything: a product with a different concentration, carrier solution or pH. Each of these variables affects effectiveness and the profile of adverse effects. It is like comparing aspirin in a tablet with a “substance based on acetylsalicylic acid” imported from an unknown pharmacy. Chemically, they may be close. In practice, the gap is considerable.
Myth 2: “Injection lipolysis destroys fat forever — the result is permanent.” Fat cells that have been broken down do not grow back. In this sense, the result is lasting. However, this does not mean your body shape will not change after the treatment. The remaining fat cells, both in nearby areas and beyond the treatment area, still respond to calories and may enlarge. How long the result lasts depends largely on what happens after the treatment: lifestyle, activity and energy balance. Injection lipolysis reduces tissue in a specific area. It is not a weight-loss method and does not replace healthy habits.
Myth 3: “Swelling and pain after the treatment are complications — something has gone wrong.” Quite the opposite. Redness, pain, swelling and a feeling of warmth after injection lipolysis are a desired inflammatory response. This is how tissue correctly reacts to the product. The body needs to break down and remove the destroyed fat cells, and this process is naturally inflammatory. Asymmetrical symptoms, symptoms lasting too long, or symptoms accompanied by skin changes require attention. A doctor, not the internet, should assess what is normal and what is not.
Myth 4: “Injection lipolysis works on every excess fat deposit — it only needs to be injected in the right place.” Injection lipolysis works only on localised deposits of subcutaneous fat that are resistant to diet and exercise. Classic examples include the so-called double chin, love handles, inner thighs and the underarm area. It does not work on visceral fat around internal organs. It also does not work in areas where fat with a different morphological structure predominates. Assessing whether a deposit qualifies for treatment requires palpation and anatomical knowledge. Diagnosis “over the internet” is not possible here.
Myth 5: “A more expensive product is only marketing — the result is the same.” The price difference between Aqualyx and a “generic” deoxycholic acid product results from several real factors: clinical research, certification, quality control and the distribution chain. A product without CE certification has not undergone independent safety verification for the European market. This does not guarantee that it will be worse. However, it also offers no guarantee that it will not be. In aesthetic medicine, the risk asymmetry is significant. A good result does not hurt. A poor one can leave a lasting mark. This is why salons focused on safety do not use products “from an unknown source”, even if they formally contain the same active substance.
Myth 6: “One treatment is enough to see a result.” The number of sessions depends on the tissue volume, the anatomy of the specific area and your individual response. It usually ranges from two to six sessions. After the first treatment, swelling is mainly visible. It gradually subsides over several weeks. The result can only be properly assessed once the inflammatory response has resolved and cellular remnants have been absorbed. This takes time. Clinics that promise a spectacular result after one session either use very high doses, with a higher risk of adverse effects, or use dishonest marketing.
Aqualyx — what sets it apart and why it is a reference point
Aqualyx is often considered an “industry standard” in injection lipolysis. This is no coincidence. The product is supported by many years of clinical research, CE certification and an established position in European aesthetic medicine. Its composition includes deoxycholic acid at a specific concentration, buffered to physiological pH, in a polyvinylpyrrolidone-cholate carrier. This combination, rather than deoxycholic acid alone, determines predictable results and the profile of adverse effects. This matters because the pH of the product directly affects how aggressively it acts on tissues and the risk of skin necrosis if administered incorrectly. A product with excessively low pH in the wrong hands presents a different level of risk from a well-buffered product in the hands of an experienced doctor.
Why prices vary — what you are actually paying for
When you compare injection lipolysis offers and see prices varying several-fold, it is worth knowing what the session fee actually covers. The product is only one element, but a key one. Certified Aqualyx from authorised European distribution costs more than an alternative imported from eastern markets. There is also the doctor’s time and experience. Precision when injecting subcutaneous tissue, the number of injection points and depth all require anatomical knowledge that cannot be gained during a weekend course. Finally, there is consultation, follow-up and any necessary touch-up. A salon that takes you seriously will plan at least two visits — treatment and follow-up — rather than sell you a “package of sessions” with no follow-up.
Injection lipolysis in women and men — the same principles, different anatomy
Injection lipolysis has long been associated with the “double chin”. However, its range of uses is wider, and your anatomy has an important influence on the treatment protocol. In women, the most common indications are the chin and neck area, love handles, inner thighs and so-called saddlebags. Subcutaneous fat tissue in women tends to have higher hydration, which affects how the product distributes after injection. In men, the aim is similar: chin, love handles and abdomen. However, the tissue is often denser and more fibrous. This may require a slightly different approach to injection depth and spacing. In both cases, the key is the same: precise assessment of the deposit before treatment and a protocol tailored to the individual, not standardised “sessions for everyone”.
Before you decide — what to establish during consultation
Injection lipolysis is a treatment that works, but only when it is properly selected and performed by a doctor who understands anatomy. There are three questions worth asking during consultation before anything is injected. First: which product does the salon use, and where does it come from? The answer should be specific: name, distributor and certification. Hesitation or a general answer such as “deoxycholic acid” is a yellow flag. Second: how many sessions do I realistically need in my case, and how did the doctor assess this? The answer should result from palpation, not from a price list. Third: what is the procedure if adverse effects occur? A salon focused on safety will have a protocol. It will not dismiss this question by saying, “that does not happen here”.
Injection lipolysis is not for everyone. This is not a drawback; it is simply medicine. There are absolute contraindications, including pregnancy, lactation, certain autoimmune conditions and active infections in the area. The result depends on palpation-based qualification, not on “I want to lose weight”. If a doctor declines treatment during consultation because the deposit does not qualify, this is a good sign. It means you have come to a place where medicine, not sales, determines the decision.
