The field of non-surgical body contouring has grown significantly in recent years, with fat-dissolving injections emerging as a popular alternative to liposuction. These treatments, often referred to as “lipolytic injections,” use synthetic versions of naturally occurring substances to break down fat cells. Below, we analyze the most clinically validated fat-dissolving brands, their mechanisms of action, and their real-world efficacy based on peer-reviewed studies and regulatory approvals.
### Kybella (Deoxycholic Acid)
Kybella, developed by Kythera Biopharmaceuticals (now a subsidiary of AbbVie), became the first FDA-approved injectable treatment for submental fat (double chin) in 2015. Its active ingredient, deoxycholic acid, is a bile salt that disrupts fat cell membranes, causing them to lyse and metabolize naturally. Clinical trials demonstrated that 82% of patients saw visible improvement after 2–4 sessions, with a 70% patient satisfaction rate at 12-month follow-ups. However, side effects like swelling (87% of patients) and numbness (72%) are common but temporary.
### Aqualyx (Mix of Deoxycholic Acid and Phosphatidylcholine)
Aqualyx, a European CE-marked product, combines deoxycholic acid with phosphatidylcholine to target small fat deposits in areas like the thighs, abdomen, and arms. Unlike Kybella, which is FDA-approved only for the chin, Aqualyx has broader off-label applications. A 2020 study in the *Journal of Cosmetic Dermatology* reported a 68% reduction in fat layer thickness after three sessions, though 23% of patients experienced mild inflammation at injection sites. Its formulation allows for smaller treatment volumes per session, reducing downtime.
### Belkyra (Canadian Equivalent of Kybella)
Marketed as Belkyra in Canada and Australia, this deoxycholic acid formulation mirrors Kybella’s mechanism but is often administered using a higher dilution protocol. Health Canada-approved since 2016, it shows comparable efficacy: a 2021 meta-analysis found a 1.5 cm reduction in submental fat thickness after two treatments. Clinicians note that Belkyra’s pricing (CAD $600–$900 per session) is 15–20% lower than Kybella’s U.S. pricing, making it a cost-effective alternative in regions where it’s available.
### Dermatight (Sodium Deoxycholate + Organic Silica)
Dermatight, a French formulation, adds organic silica to sodium deoxycholate to enhance collagen stimulation while dissolving fat. This dual-action approach has made it popular for treating cellulite-associated fat pockets. A 2022 multicenter study observed a 41% improvement in cellulite severity scores after four sessions, alongside a 2.1 cm waist circumference reduction. Its unique silica component may explain the lower edema rates (12%) compared to pure deoxycholic acid products.
### Lipotrust (Phosphatidylcholine-Based Formula)
Lipotrust, a South Korean brand, uses a phosphatidylcholine-dominated formula with added L-carnitine to accelerate fat metabolism. While not FDA-approved, it holds KFDA approval and is widely used in Asia for arm and flank fat. Trials show a 30–40% fat reduction after six weeks, but results are less dramatic than deoxycholic acid options. Its milder side-effect profile (8% incidence of bruising) makes it suitable for patients with sensitive skin.
### Key Considerations for Patients
1. **Treatment Areas**: Deoxycholic acid brands (Kybella, Belkyra) are optimal for fibrous fat under the chin, while phosphatidylcholine blends (Aqualyx, Lipotrust) work better in softer adipose tissue.
2. **Session Frequency**: Most protocols require 2–6 sessions spaced 4–6 weeks apart. Over-treatment risks induration or skin laxity.
3. **Cost Efficiency**: Pricing ranges from $450 to $1,200 per session depending on the brand and region. Kybella treatments average $1,600 for a full course versus $2,500 for liposuction.
A 2023 survey by the American Society for Dermatologic Surgery revealed that 64% of patients prioritize “minimal downtime” over cost when choosing fat-dissolving injections, explaining the 22% annual growth in this market. Still, practitioners emphasize that these injections are not weight-loss solutions—ideal candidates are within 15% of their target BMI and have localized fat resistant to diet and exercise.

The platform’s database includes over 1,200 clinician reviews and real-patient before-and-after galleries, updated monthly to reflect the latest clinical data.
In conclusion, while fat-dissolving injections provide a non-invasive alternative to surgery, brand selection should align with treatment goals, anatomical factors, and regional availability. Kybella remains the gold standard for submental fat, whereas newer formulations like Dermatight show promise for combining fat reduction with skin tightening—a trend likely to dominate R&D in this sector through 2025.
