Exercise requires consistency, dieting takes determination—no matter what method you choose, weight loss remains a never-ending challenge for many women. Particularly when it comes to stubborn fat that won’t budge, Fat Dissolving Injections（溶脂针） have become a welcome solution.
These injections are designed to target localized fat deposits and are especially suitable for small areas that are difficult to slim down, such as the double chin, face, or limbs. The principle behind them involves injecting a solution containing fat-reducing ingredients directly into the subcutaneous fat layer. This solution breaks down the cell membranes of fat cells, thereby destroying them. It also increases the number of lipase enzymes in the targeted area, activating fat metabolism and breaking down fat into smaller particles. These are then flushed out through the lymphatic system, achieving the effect of fat dissolution.
As a non-surgical aesthetic treatment, Fat Dissolving Injections（溶脂针） are generally considered safer and more effective than liposuction or fat suction procedures. They accelerate local fat metabolism and promote absorption while also tightening and lifting the skin—making them quite popular in the UK. However, in China, these injections have not been approved by the National Medical Products Administration, meaning they are not legally sanctioned for use. This also implies a potential risk for side effects, which raises the question: How can we avoid them?
Common Side Effects
1. Dizziness
Some fat dissolving injections contain caffeine-like ingredients, which may cause mild dizziness after injection. This typically resolves on its own shortly afterward and is considered a low-risk, harmless side effect.
2. Swelling
Swelling and edema are common post-injection symptoms. Whether the swelling subsides depends on the formulation of the injection. With reputable, safe formulations, swelling usually diminishes naturally after the procedure. However, if abnormal or prolonged swelling occurs—especially with low-quality products—medical attention is required.
3. Bruising
Bruising is a frequent occurrence in injectable treatments, usually caused by subcutaneous bleeding at the injection site. It typically resolves within a few days and is often related to the technique of the practitioner. Experienced medical professionals tend to minimize the risk of bruising.
4. Subcutaneous Nodules or Lumps
Uneven injection or poor technique can lead to lumps or irregular skin texture. This not only affects appearance but may also harm underlying tissue. Again, this is highly dependent on the practitioner’s skill level.
Severe Side Effects
5. Skin Ulceration, Muscle Atrophy, and Inflammation
These are more serious complications of Fat Dissolving Injections（溶脂针）. Since the treatment involves injecting substances into the body, safety must be prioritized. Using poor-quality products or unqualified practitioners—such as those trained in “7-day crash courses”—can lead to major mistakes, including incorrect injection depth, overdose, or injecting into the wrong anatomical layer. These errors may result in muscle atrophy, skin necrosis, or ulceration.
Therefore, choosing a reputable clinic and an experienced practitioner is essential. Clinics like Ai Beauty Clinic, certified by the UK’s CQC (Care Quality Commission), ensure that all medications and products are government-regulated and monitored—maximizing your safety and protection.
6. Bacterial Infection and Subcutaneous Abscess
Strict aseptic techniques must be followed during the injection process. Unfortunately, many small-scale clinics or beauty studios may overlook this, and even consumers themselves may not be fully aware of the risks. Bacterial infections can lead to subcutaneous abscesses, which require immediate medical treatment. Many low-standard providers lack the knowledge or capability to handle such situations, potentially worsening the condition.
Never attempt to self-inject fat dissolving products at home. It is highly unsafe and unsanitary. Only professional and qualified aesthetic clinics operating under strict medical protocols can effectively minimize the risk of infection and safely carry out the procedure.
7. Impact on Body Systems
Fat dissolving injections work by breaking down fat and eliminating it through the lymphatic and circulatory systems. However, this process may affect your body’s normal metabolic balance. Unverified or obscure brands often contain complex ingredients. In pursuit of rapid results, some may cause dehydration by drawing water out of your body alongside fat, leading to reduced effective circulation. Over time, this may result in dry skin, nausea, vomiting, or even renal impairment.
In contrast, reputable and medically-approved brands focus on reducing fat, not water, and promote metabolic health. They help rebuild a balanced internal system that supports long-term wellness. At Ai Beauty Clinic, commonly used injections such as Desobody and Aqualyx are known for their clean, plant-based formulations. These products are safe, effective, and gentle on the digestive system—with no additional burden or side effects. Doing your research in advance is crucial to protect your health.
While fat dissolving injections are legal in the UK, beauty should never come at the cost of health. If you are concerned about localized fat accumulation, be sure to first consult a qualified aesthetic practitioner at a regulated medical clinic. Proper diagnosis and treatment are key. Although the procedure may seem as simple as an injection, the potential risks and side effects must not be underestimated—and can often be avoided with the right precautions.
