Fat-Dissolving Injections Myths: Are These Injections Effective For Weight Loss?

Many people who want to lose fat effectively without spending hours exercising or risking unhealthy crash diets turn to fat-dissolving injections. These treatments target stubborn areas for spot reduction, helping to restore a curvier, more sculpted figure.

But have you ever wondered — are fat-dissolving injections truly safe and effective? How exactly do they work? What are the possible side effects? In this article, we’ll bust some common myths about fat-dissolving injections, so you can better understand the method, avoid risks, and slim down safely with defined body contours!

1

Do Fat-Dissolving Injections Have Safety Certification?

One of the most common brands of fat-dissolving injections on the market is Belkyra, which received FDA (U.S. Food and Drug Administration) approval in 2017 for eliminating submental fat (commonly known as a double chin).

Most qualified clinics and practitioners use FDA-certified products to ensure safety. Besides FDA approval, Belkyra also holds the European CE (Conformité Européenne) certification.

Interestingly, Belkyra’s original name was Kybella. It was later acquired and rebranded by the major U.S. pharmaceutical company Allergan — the same manufacturer behind the famous cosmetic injectable Botox.

How Do Fat-Dissolving Injections Work? Unveiling the Science Behind Fat-Dissolving Injections

Fat-dissolving injections involve injecting a specific formulation into targeted areas. These formulations typically include ingredients like deoxycholic acid, phosphatidylcholine, and saline solution. They work by breaking down the membranes of stubborn fat cells under the skin, turning fat into waste that is gradually expelled from the body through natural metabolic processes, reducing the burden on detoxifying organs like the kidneys.

In medical aesthetics, this fat-dissolving method is known as mesotherapy or mesoderm therapy. It uses chemical agents to selectively destroy fat cells.

Typically, fat-dissolving injections are used for localized fat reduction, such as in areas like the chin, arms, and calves. They also enhance blood circulation, helping the skin regain elasticity, tighten, and lift for a mild body-sculpting effect.

What Are the Benefits of Fat-Dissolving Injections? Are They Really Effective for Weight Loss?

There are valid reasons why fat-dissolving injections are considered a reliable and safe fat-reduction method. Compared to weight loss pills, the certified approval of these injections — particularly FDA clearance for double chin treatment — gives many women peace of mind. FDA certification involves stringent testing and rigorous standards to protect consumer safety, and many clinical studies support the effectiveness of fat-dissolving injections for double chin reduction.

The major advantage of fat-dissolving injections over other weight-loss methods is that they don’t require surgery or anesthesia. The pain is relatively mild, and the recovery time is short, making it an excellent option for busy office workers who can return to daily life quickly without major disruptions.

Moreover, because no surgery is involved, fat-dissolving injections are suitable for people who are not candidates for surgery. And unlike surgical procedures where results can vary based on the surgeon’s technique, the outcome of fat-dissolving injections is more consistent and reliable.

Another key reason for their popularity is their ability to target specific problem areas. Many experienced dieters know how frustrating it can be to lose fat from the “wrong” areas while stubborn spots — like the double chin and cheeks — refuse to budge, even with strict dieting and exercise. Fat-dissolving injections address this frustration by precisely targeting small, hard-to-slim-down areas, offering tailored, localized fat reduction.

5 Must-Know Facts Before Getting Fat-Dissolving Injections: Potential Side Effects and Risks

Short-Term and Long-Term Side Effects

Fat-dissolving injections may cause immediate side effects like swelling and pain, but there are also serious long-term risks to consider, including:

• Difficulty swallowing
• Jaw nerve injury
• Uncontrolled facial muscle movements
• Hair loss
• Severe allergic reactions
• Skin necrosis and ulceration

It’s important to note that the FDA currently only approves fat-dissolving injections for double chin treatment. Their use on other areas like the thighs or arms remains unverified, meaning the effectiveness and risks are still uncertain.

Limitations of Fat-Dissolving Injections

While you can choose specific areas for injection, the effects are not permanent. The chemical compounds increase the load on internal organs, so the amount injected must be limited each time.

To achieve noticeable results, multiple sessions are often required at the same site. Sessions should be spaced at least one month apart to allow full recovery from swelling and bruising. Moreover, if a person gains weight again after treatment, the fat can re-accumulate, undoing the results.

Who Should Avoid Fat-Dissolving Injections?

Although recovery is quick, certain groups should absolutely avoid fat-dissolving injections:

• Pregnant women
• Women preparing for pregnancy or breastfeeding
• Those on their menstrual period (it's better to avoid injections during this time to minimize bodily stress)

Additionally, people with the following conditions should not undergo fat-dissolving injections:

• Heart disease
• Hypertension
• Diabetes
• Swallowing difficulties
• Thyroid disorders
• Kidney diseases
• Hemophilia
• Active infections
• Soy allergies (due to the ingredients used)

Consulting a qualified doctor for a thorough risk assessment is strongly recommended.

Why Some Countries Have Banned Fat-Dissolving Injections

Medically, fat-dissolving injections were originally developed to dissolve fat embolisms and clear vascular blockages, not for cosmetic body-slimming purposes. While Hong Kong currently has no legislation regulating fat-dissolving injections, several countries — including China, Japan, the UK, and Brazil — have banned their sale and use due to high risks of serious side effects like bacterial infections.

Even though the FDA approved their use for the double chin, no detailed regulations have been set on how they should be used in practice.

Lack of Regulation and Quality Control

In Hong Kong, there are no laws regulating who can administer fat-dissolving injections. Many online shops illegally sell injections for self-administration, posing serious dangers.

Problems include:

• Unknown product origins
• Unverified ingredients
• Lack of quality control
• Poor storage practices

If allergic reactions or complications occur, treatment becomes more difficult because the exact contents of the injections are unknown. Injections contaminated with bacteria can cause devastating infections with serious consequences.

While fat-dissolving injections offer the tempting promise of targeted fat loss — especially for stubborn areas like the double chin or cheeks — they come with real risks. Doctors warn that the face contains delicate nerves and salivary glands, and inexperienced injections can easily cause nerve damage, inflammation, or severe complications.

Moreover, in the pursuit of faster results, some manufacturers mix unapproved ingredients into their formulations, increasing the risk of serious side effects like allergies, organ stress, and skin ulcers.

In short: before choosing fat-dissolving injections, think carefully. Is it really worth risking your health for cosmetic results?

Things to Watch Out for After Fat-Dissolving Injections

Fat-Dissolving Injection Aftercare 1: Physical Reactions

After receiving fat-dissolving injections, it is normal to experience fatigue, discomfort, dizziness, weakness, nausea, and numbness. Swelling, pain, burning sensations, inflammation, and even pus formation may occur at the injection site, sometimes accompanied by bruising. A small number of people may also develop a fever. It’s important to rest and drink plenty of water about an hour after the injection.

Fat-Dissolving Injection Aftercare 2: Diet

For one week after the procedure, avoid alcohol and spicy or stimulating foods such as chili and seafood. Otherwise, the body may react adversely, leading to allergic reactions.

Fat-Dissolving Injection Aftercare 3: Exercise

You should avoid overexertion and intense exercise after fat-dissolving injections. If pain or bruising occurs, apply a cold compress gently. For sensitive individuals, hardened areas or nodules may form under the skin after bruising resolves, leading to tenderness. Most people will see improvements after sufficient rest, but those with severe symptoms should seek medical advice promptly.

Fat-Dissolving Injection Aftercare 4: Skincare

Within 24 hours of injection, avoid getting the area wet or applying topical medications or any irritants near the injection site to prevent delaying healing. When cleaning, use only clean water. Do not apply makeup or skincare products with heavy fragrances or chemicals near the injection points.

Fat-Dissolving Injections vs. Laser Lipolysis — Which Is Better?

Although fat-dissolving injections don't require surgery, they are still an invasive procedure with certain risks, and there is currently a lack of regulatory legislation in Hong Kong. So, what other options are there to remove stubborn fat from areas like the double chin or chubby cheeks? How does fat-dissolving injection compare to laser lipolysis?

Fat-Dissolving Injection vs. Laser Lipolysis 1: Treatment Areas

Fat-dissolving injections are mainly suitable for localized fat reduction. The U.S. FDA has only approved their use for double chin reduction. However, many beauty clinics and shops also claim they can be used for slimming areas like the cheeks and calves.

Laser lipolysis, on the other hand, can target a broader range of stubborn fat areas such as the flanks, thighs, arms, back, upper buttocks, and more, offering a more comprehensive and noticeable fat-reduction effect.

Fat-Dissolving Injection vs. Laser Lipolysis 2: Invasiveness

Fat-dissolving injections are invasive, involving the direct injection of chemical agents that break down fat cells. There remains a potential risk of chemical residues causing harm or triggering allergic reactions. Some manufacturers, aiming for faster results, mix uncertified ingredients, significantly increasing the risk of side effects such as allergies, infections, organ strain, or even skin necrosis.

Laser lipolysis, however, is non-invasive. It uses biolaser technology to penetrate the subcutaneous fat layer, breaking down fat cells and stimulating the release of fatty acids. Combined with vacuum suction, it promotes lymphatic drainage, naturally expelling dead fat cells without damaging or burning the surrounding tissues.

Fat-Dissolving Injection vs. Laser Lipolysis 3: Duration of Results

Results from fat-dissolving injections typically last 8 to 12 days. Once fat accumulates again, additional injections are required. Because the chemical agents place a strain on internal organs, the quantity injected must be carefully limited. To achieve noticeable fat reduction, multiple injections in the same area are often necessary, with sessions spaced at least a month apart to allow the body to recover fully from swelling and bruising.

Conversely, laser lipolysis uses a photothermal effect to destroy excess fat cells and promote lymphatic drainage. Results are usually visible after the first treatment and continue to improve over time, with fat reduction effects typically lasting 1 to 3 months.

Editor's Experience: Want to Try Fat-Dissolving Injections but Feeling Nervous? Try Body Sculpting Machines Instead!

Fat-dissolving and slimming injections have become increasingly popular, but since Hong Kong hasn't legislated to regulate these treatments, some people even dangerously self-inject slimming shots bought online — a truly alarming trend.

Booking was incredibly easy: fill out a form in a minute, receive a confirmation SMS, and simply show it at the clinic to enjoy a free trial session! During the treatment, I only felt a gentle warmth on my tummy. The whole process was quick and comfortable. The latter part of the session used a vacuum device to massage the treatment area, accelerating metabolism and fat elimination for even better slimming results.

Another pleasant surprise was the in-depth consultation with a professional consultant, where I not only learned more about the treatment's principles but also received practical weight-loss tips to incorporate into my daily habits. And the big question — how much did I slim down? After my weight stabilized, I lost 2 cm around my waist! My abdominal contour became much tighter, and even bloating disappeared.
