Stylage® XXL (2 x 1.0 mL) | Laboratoires VIVACY

Short Description

The ultimate structural volumizer in the VIVACY aesthetic portfolio, Stylage® XXL combines 21 mg/g of high-density cross-linked Hyaluronic Acid with patented IPN-Like technology and the antioxidant Mannitol. Engineered with the highest elastic modulus ($G’$) and projection capacity in the Stylage range, it is specifically designed for deep subcutaneous and supraperiosteal placement to reconstruct lost facial volume, sculpt the zygomatic arch, and define the chin and mandibular contour.

Detailed Description

Stylage® XXL is an advanced, sterile, non-pyrogenic physiological cross-linked sodium hyaluronate dermal implant developed by Laboratoires VIVACY in France. It is formulated utilizing proprietary IPN-Like Technology (InterPenetrated Cross-Linked Networks), which interweaves two distinct monophasic cross-linked HA networks. This molecular architecture produces high cohesivity, maximum elasticity, and robust resistance to mechanical shear stress from hyperactive facial dynamics.

A signature hallmark of the formulation is the incorporation of Mannitol, a potent physiological antioxidant. Mannitol acts as a protective shield against reactive oxygen species (ROS) released during mechanical needle or cannula trauma, significantly blunting immediate post-injection swelling, bruising, and inflammatory degradation of the HA chains. Administered via VIVACY’s ergonomic Bi-Soft® delivery system, Stylage XXL delivers precise volumetric projection and bone-mimetic architecture without displacement or lateral flattening.

Treatment Areas & Indications

• Extreme Midface Volumization & Malar Projection:

  • Severe midface volume deficit and age-related cheek hollowing

  • Zygomatic arch definition and high cheekbone sculpting

  • Deep submalar and pre-auricular fat pad restoration

• Lower Face Structural Contouring & Harmonization:

  • Pronounced chin augmentation, projection, and elongation (microgenia / retrogenia correction)

  • Mandibular angle definition and sharp linear jawline contouring

  • Severe pre-jowl sulcus effacement

• Deep Structural Deficits:

  • Deep temporal hollow reconstruction (temple lifting)

  • Facial lipodystrophy / severe soft tissue atrophy restoration

Key Clinical Advantages

• Patented IPN-Like Technology: Dual-network cross-linking provides superior cohesive density and the highest lifting capacity ($G’$) in the Stylage family, holding targeted vertical projection in high-tension anatomical planes.

• Mannitol Antioxidant Protection: Effectively neutralizes free radicals at the injection site, reducing immediate post-procedure edema, erythema, and premature bio-degradation.

• Patented Bi-Soft® Syringe Delivery: Housed in VIVACY’s award-winning Bi-Soft® syringe design with an ergonomic grip, centered center of gravity, and reduced extrusion force for steady, high-viscosity placement.

• Natural Tissue Integration: Despite its high volumetric density, the cohesive matrix integrates smoothly over the periosteum and deep fat compartments, preventing palpability, nodules, or unnatural stiffness.

• Available with Lidocaine: Offered in both standard and lidocaine-infused formulations (Stylage XXL with Lidocaine 0.3%) for improved patient comfort during deep bolus extrusion.

• Extended Clinical Durability: Highly resistant to hyaluronidase and enzymatic degradation, maintaining structural projection for 12 to 18+ months.
