Key Takeaways
- Aesthetic practitioners use Liporase, an injectable hyaluronidase enzyme, to efficiently dissolve hyaluronic acid (HA) fillers, especially in cases of overfilling, asymmetry, and vascular complications.
- It works by breaking down cross-linked HA molecules through enzymatic action, reducing viscosity and volume, which allows for quick and controlled filler degradation.
- Liporase comes in 1,500 IU lyophilized powder form, and practitioners must reconstitute it with sterile saline or distilled water before injection. Proper dilution is essential to ensure effective and safe treatment outcomes.
- Manufacturers derive the enzyme from bovine/ovine sources or produce it through recombinant formulations, with each type carrying different immunogenic risks and requiring specific dosing protocols.
- Clinicians commonly use Liporase for filler reversal, vascular occlusion management, edema reduction, and as an adjunct to fat-dissolving treatments.
- Compared to other hyaluronidase products, such as Hylenex and Vitrase, Liporase is more affordable but lacks FDA approval in certain regions, which can limit its legal use.

Liporase Composition & Pharmacologic Action
Liporase is a specialized injectable enzyme widely used in aesthetic medicine for the safe and efficient dissolution of hyaluronic acid (HA) fillers. Its effectiveness lies in its unique biochemical action, which targets and breaks down HA molecules without causing harm to the surrounding tissues. Understanding how Liporase works can help both patients and clinicians appreciate its role in filler correction and managing complications.
Key Features of Liporase
- Hyaluronidase is the active enzyme in Liporase, which catalyzes the breakdown of hyaluronic acid by hydrolyzing glycosidic bonds in the extracellular matrix.
- This enzymatic action reduces the viscosity and volume of HA fillers, making them easier to dissolve and remove.
- Liporase formulations may originate from animal (bovine/ovine) or recombinant sources, resulting in slight compositional differences while preserving consistent enzymatic activity.
- Its ability to specifically target cross-linked HA molecules makes Liporase effective for correcting overfilling, uneven results, or addressing vascular complications.
- Widely used in both cosmetic and medical contexts, Liporase provides rapid and controlled filler degradation, improving safety and aesthetic outcomes.
Liporase’s enzymatic mechanism forms the core of its clinical utility. By efficiently breaking down HA fillers, it serves as an essential tool for practitioners managing filler revisions and emergencies. Understanding its action allows for better treatment planning and patient education.
Formats: 1,500 IU Powder & Standard Dilution Protocols
Liporase is typically provided as a sterile lyophilized powder, most commonly packaged in 1,500 IU vials. Before injection, reconstitute the powder with sterile normal saline or distilled water, and always use aseptic technique to prevent contamination and preserve enzymatic integrity, especially when treating sensitive areas like the face or under the eyes.
Dilution protocols can vary depending on the clinical objective, whether dissolving superficial filler, treating edema, or managing vascular emergencies. Use a standard dilution ratio of 1:4, where 1,500 IU of Liporase is mixed with 6 mL of saline, to ensure uniform enzymatic activity and consistent outcomes across varied injection sites.
Proper dilution is crucial for effective hydroxyapatite (HA) breakdown and minimizing the risk of adverse events. Inaccurate mixing—whether too concentrated or too weak—can result in suboptimal filler reversal or elevate the likelihood of discomfort, bruising, or allergic reactions. To avoid unwanted Liporase side effects, practitioners must follow the manufacturer’s instructions or established clinical guidelines precisely.
Clinical Uses: Filler Reversal, Vascular Emergencies, Edema
Liporase is a versatile injectable enzyme with a range of applications in both emergency and elective aesthetic procedures. While it is most commonly used to reverse hyaluronic acid (HA) fillers, its clinical value extends far beyond filler correction. Understanding its multiple uses helps practitioners integrate it more effectively into their treatment protocols.
- Filler Dissolution: Best known for reversing the effects of HA fillers. It breaks down cross-linked HA rapidly and efficiently, making it the go-to solution for patients experiencing overfilling, asymmetry, or migration of dermal filler.
- Vascular Occlusion Management: In urgent cases of intravascular filler injection, administer Liporase immediately to dissolve the obstructing HA, restore blood flow, and prevent tissue necrosis—a gold standard approach in managing filler-related complications.
- Edema Reduction: Can help manage localized swelling caused by excess hyaluronic acid or lymphatic congestion. Its ability to break down residual HA helps reduce puffiness and improve skin contour in affected areas.
- Adjunct to Fat-Dissolving Treatments: Some clinicians incorporate Liporase to enhance the effects of fat-reduction procedures. By modulating extracellular HA, it enhances the spread and efficacy of fat-dissolving compounds, such as deoxycholate-based injectables.
Liporase’s effectiveness in both corrective and supportive roles reinforces its value in cosmetic medicine. Whether addressing emergencies or fine-tuning results, its adaptability makes it an essential tool in a practitioner’s aesthetic toolkit.
Comparison to Other Hyaluronidase Products
While Liporase is widely used in aesthetic and clinical practice, it’s important to compare it with other hyaluronidase products available on the market. Variations in enzyme source, formulation, approval status, and safety profile can influence a practitioner’s choice. Below is a comparative overview of three leading hyaluronidase options: Liporase, Hylenex, and Vitrase.
| Product | Source | Formulation Type | FDA Approval | Immunogenic Risk | Notes on Use |
| Liporase | Bovine/ovine-derived | Lyophilized powder (1,500 IU) | Not FDA approved in the U.S. | Moderate (due to animal protein content) | Popular in Asia; requires reconstitution; see Liporase side effect discussion for allergic considerations. |
| Hylenex | Recombinant human | Premixed solution (150 USP/mL) | FDA approved | Low | Ideal for HA filler reversal and drug dispersion; widely accepted in clinical protocols. |
| Vitrase | Ovine-derived | Lyophilized powder (200 USP) | FDA approved | Moderate | Used for aiding absorption of other drugs and filler breakdown; requires reconstitution. |
Liporase stands out for its affordability and widespread availability in international markets; however, its lack of FDA approval can limit its legal use in certain countries. In contrast, Hylenex and Vitrase offer more consistent dosing and lower immunogenic risk due to recombinant or purified sources.
Regardless of product choice, clinicians must monitor patient responses and be aware of the unique Liporase side effects or reaction profiles that may arise.
Conclusion
Understanding Liporase and its pharmacologic action allows practitioners to apply it effectively for filler corrections and urgent medical interventions. As a hyaluronidase-based injectable, Liporase works by breaking down cross-linked hyaluronic acid, making it ideal for managing overfilled areas, migration, and vascular complications. Clinicians rely on its fast-acting enzymatic action to restore natural facial contours or resolve filler-related risks when used correctly and in accordance with appropriate dilution protocols.
Liporase is generally well-tolerated, but side effects may occur if patient allergies, contraindications, or dosing inaccuracies are overlooked. Despite its lack of FDA approval in some countries, Liporase continues to gain global acceptance due to its dependable clinical outcomes and strong endorsements from practitioners. Its value lies in its precision, preparation, and informed usage, ensuring optimal outcomes for patients and practitioners alike.
