Stylage Bi-Flex XXL
Stylage Bi-Flex XXL is a cross-linked hyaluronic acid dermal filler produced by Laboratoires VIVACY in France, formulated for facial restructuring and contouring. It is chosen by clinics and aesthetic physicians for precise, sharp restructuration of the jawline, chin, mandibular angle and cheekbones. The gel contains 21 mg/mL of cross-linked hyaluronic acid in a phosphate buffer enriched with mannitol (35 mg/g) together with mepivacaine hydrochloride 0.3% w/w, is placed in the deep dermis or subcutaneously, and is supplied in the Bi-FLEX syringe system for professional use by qualified practitioners only.
Key Benefits of Stylage Bi-Flex XXL
- For facial restructuring and contouring, with precise and sharp restructuration of facial contours
- Contains 21 mg/mL cross-linked hyaluronic acid with mannitol 35 mg/g and mepivacaine hydrochloride 0.3% w/w
- The anaesthetic is mepivacaine, not the lidocaine used elsewhere in the STYLAGE range
- Highly cohesive gel with high projection capacity - in VIVACY's preclinical CT-scan study its projection capacity was higher than STYLAGE XL's
- Good tissue integration, slow degradation and a long-lasting effect, with great tolerance
- Over 70% improvement after 18 months on GAIS subject assessment, with chin volume change sustained up to 18 months
- Supplied with 27G half-inch needles and a 25G 40 mm cannula with pre-hole needle
- Bi-FLEX patented syringe - a new flexible design that adapts to the practitioner's hand, with a flexible plunger head and a bi-material soft-touch grip
- CE-marked Class III medical device (CE 0344), made in France
Indications and Professional Use
Main indications
- Restoration or augmentation of facial volume
- Facial restructuring and contouring
- Jawline and mandibular angle definition
- Chin augmentation
- Cheekbone and facial angle sharpening
Professional use
Stylage Bi-Flex XXL is a Class III medical device (CE 0344), non-reimbursable, intended for administration by qualified medical practitioners trained in volumising and contouring dermal filler technique, using aseptic technique. VIVACY specifies a deep dermal or subcutaneous injection plan, with linear threading injection, multipoint injection or a combination of both, using 27G half-inch needles or the supplied 25G 40 mm cannula. Note that the anaesthetic in this reference is mepivacaine hydrochloride 0.3% w/w, not the lidocaine used elsewhere in the range, so anaesthetic sensitivity must be screened against mepivacaine specifically before treatment. Jawline and mandibular angle work at depth demands anatomical familiarity with the region. Consult the instructions for use before injection. Injection technique and volume per treatment area are determined by the practitioner.
Treatment areas
- Chin
- Jawline
- Mandibular angle
- Cheekbones
Patient profile
Suitable for adult patients seeking definition of the jawline, chin, mandibular angle or cheekbones, or correction of facial volume loss or displacement affecting facial balance, as assessed by a qualified practitioner. Patients seeking wrinkle correction are better served by the S, M or L references, and those seeking midface volume by the XL reference. Where the mepivacaine presentation is supplied, patients with known sensitivity to amide-type local anaesthetics, and to mepivacaine in particular, are not candidates. Patient selection follows the manufacturer's Instructions for Use, which must be consulted before injection.
How Stylage Bi-Flex XXL Works
Stylage Bi-Flex XXL works through cross-linked hyaluronic acid at 21 mg/mL placed in the deep dermis or subcutaneously, where the manufacturer describes it as providing high projection capacity for precise, sharp restructuring of facial contours. Its behaviour comes from its rheology rather than concentration alone: viscosity and sculptability are what allow it to define a jawline or a mandibular angle and hold that definition, which is a different task from filling a wrinkle. Slow degradation is described as giving a long-lasting effect. The phosphate buffer is enriched with mannitol at 35 mg/g, and the anaesthetic is mepivacaine hydrochloride 0.3%.

Frequently Asked Questions
Which anaesthetic does Stylage Bi-Flex XXL use?
Mepivacaine hydrochloride 0.3% w/w, rather than the lidocaine used elsewhere in the STYLAGE range. VIVACY also supplies a presentation without mepivacaine.
How does Stylage Bi-Flex XXL differ from Stylage Bi-Flex XL Lidocaine?
XXL is the restructuring reference, for the jawline, chin, mandibular angle and cheekbones. At 21 mg/mL it is rheologically firmer than the 26 mg/mL XL and delivers higher projection: in VIVACY's preclinical CT-scan comparison its projection capacity exceeded XL's. XL is adapted for midface remodelling in the cheeks, cheekbones and temples.
Where is Stylage Bi-Flex XXL injected?
VIVACY specifies the deep dermis or the subcutaneous plane, using linear threading injection, multipoint injection or a combination of both, with 27G half-inch needles or the supplied 25G 40 mm cannula.
How long does Stylage Bi-Flex XXL last?
VIVACY reports proven efficacy and safety up to 18 months, with over 70% improvement after 18 months on GAIS subject assessment. In its controlled study the product was significantly superior to no-treatment control from baseline to 6 months, and the chin volume change was sustained up to 18 months.
