In modern aesthetic medicine, hyaluronic acid dermal fillers have become essential tools for facial rejuvenation, volume restoration, and contouring. Their versatility, safety profile, and minimally invasive application make them a mainstay in clinical practice worldwide.
Among the most popular filler lines is Saypha®, developed by Croma Pharma, which offers a wide range of formulations for different indications: wrinkle correction, lip enhancement, contouring, and deep volume restoration.
One of the most frequently asked questions among practitioners is: Can you mix Saypha with lidocaine? This question arises from the increasing demand to improve patient comfort during procedures, particularly in sensitive areas such as lips and perioral regions.
This technical guide provides a comprehensive overview for intermediate and advanced injectors, analyzing:
- Saypha’s composition
- The role of lidocaine in fillers
- Benefits and risks of mixing
- Scientific evidence and regulatory considerations
- Practical clinical recommendations
Composition of Saypha Fillers
Saypha® fillers are based on highly purified, non-animal hyaluronic acid, stabilized using the patented S.M.A.R.T. technology (Supreme Monophasic And Reticulated Technology).
Key features
- Monophasic structure for smooth injection
- Different cross-linking levels depending on indication
- High biocompatibility and purity
- Designed for consistent and natural results
In most standard formulations, Saypha does not include lidocaine (though certain “with lidocaine” versions exist in some markets). This explains why many practitioners consider whether it is possible, safe, and effective to mix Saypha with lidocaine in daily practice.
What Is Lidocaine and Why Add It to Fillers?
Lidocaine is a well-established local anesthetic commonly used in both medicine and dentistry. In aesthetic practice, its addition to dermal fillers has several advantages:
- Pain reduction during and after injection
- Decreased patient anxiety, leading to better cooperation
- Greater precision for the injector, especially in sensitive areas
- Improved patient satisfaction and overall treatment experience
For this reason, many filler manufacturers now release pre-formulated versions with lidocaine. However, when it is not included, some professionals explore the option of manually mixing lidocaine with fillers like Saypha.
Can You Mix Saypha with Lidocaine?
From a purely technical standpoint, yes, it is possible to mix Saypha with lidocaine, since hyaluronic acid gels are hydrophilic and compatible with local anesthetics.
However, the key questions for professionals are:
- Is it safe?
- Does it affect the filler’s efficacy or longevity?
- Is it approved by the manufacturer and regulatory authorities?
Regulatory considerations
- Croma Pharma, Saypha’s manufacturer, does not officially recommend altering the product’s formulation.
- All Saypha products are approved in their original composition (with CE mark, FDA clearance in certain markets).
- Any modification constitutes an off-label use, transferring responsibility entirely to the physician.
Benefits of Mixing Saypha with Lidocaine
Many practitioners report positive experiences when they mix Saypha with lidocaine. The benefits most often cited include:
- Improved patient comfort
– Less pain, particularly in lips, nasolabial folds, or perioral lines. - Reduced anxiety
– Patients are more relaxed, leading to smoother procedures. - Enhanced precision
– Pain-free patients allow injectors to focus on technique and symmetry. - Differentiation in patient care
– Enhanced comfort can become a competitive advantage for clinics.
Risks and Limitations
Despite its benefits, practitioners must also consider the risks of mixing:
- Altered rheology
– Dilution may affect the viscoelastic properties of the gel, reducing projection. - Decreased cohesivity
– May increase the risk of product migration. - Higher incidence of edema
– Lidocaine has vasodilatory properties, which can contribute to swelling. - Legal implications
– Any modification is off-label, and liability falls solely on the injector.
Comparison of Saypha® Fillers: With and Without Lidocaine
When considering whether to mix Saypha with lidocaine, it is important to note that several Saypha® products are already available in pre-formulated versions with lidocaine. These options may offer a safer and more convenient alternative, avoiding the risks associated with off-label mixing. The following table provides a comparison of the main Saypha fillers currently available, including their concentrations, formulations, and prices.
| Product | Concentration | Presentation | With Lidocaine | Price | Main Indications |
|---|---|---|---|---|---|
| Saypha® Filler | 23 mg/ml | 1 ml prefilled syringe | No | €41.00 | Moderate wrinkles, nasolabial folds |
| Saypha® Volume | 23 mg/ml | 1 ml prefilled syringe | No | €42.00 | Deep volume restoration, cheeks |
| Saypha® Rich | 18–20 mg/ml | 1 ml prefilled syringe | No | €30.00 | Skin revitalization, hydration |
| Saypha® Volume Plus with Lidocaine | 23 mg/ml + 3 mg/ml | 1 ml prefilled syringe | Yes | €58.00 | Volume restoration with added comfort |
| Saypha® Filler with Lidocaine | 23 mg/ml + 3 mg/ml | 1 ml prefilled syringe | Yes | €45.00 | Wrinkle correction with integrated analgesia |
| Saypha® Volume with Lidocaine | 23 mg/ml + 3 mg/ml | 1 ml prefilled syringe | Yes | €48.00 | Structural volume with improved comfort |
This comparison illustrates how professionals can choose between standard Saypha formulations and ready-to-use versions with lidocaine. In many cases, purchasing pre-formulated products may reduce risks and streamline clinical practice, compared to manually mixing Saypha with lidocaine.

Scientific Evidence
The scientific literature on mixing Saypha with lidocaine is limited, as clinical trials typically assess fillers in their original, approved formulations.
Still, relevant insights can be drawn from:
- Clinical reports in cosmetic dermatology journals, where lidocaine addition improved patient comfort, especially in lip procedures
- Conference presentations, where experienced injectors describe positive outcomes using controlled dilution
- Other filler lines (e.g., Juvederm, Restylane) that include lidocaine in their commercial versions, supporting overall compatibility
Practical Clinical Protocols (Educational Purpose)
Disclaimer: The following recommendations are for educational purposes only. Any modification is off-label and performed at the injector’s own risk.
Typical proportions reported in practice
- Add 0.1–0.2 ml of lidocaine (2%) per 1 ml of Saypha.
Suggested procedure
- Draw the required amount of sterile lidocaine.
- Introduce carefully into the Saypha syringe.
- Mix gently by alternating plunger pressure to homogenize.
- Inject following the standard technique.
Key Recommendations for Professionals
- Assess indication carefully: not all patients require lidocaine
- Inform the patient: clarify that this is an off-label adjustment
- Use minimal volumes: avoid over-diluting the filler
- Document in medical records: include details of modification
- Prefer official formulations: when available, use Saypha “with lidocaine” to remain within approved practice
