Stylage is a hyaluronic acid dermal filler range manufactured by Laboratoires Vivacy in France, built around a patented crosslinking technology called IPN-Like and exported to more than 80 countries. The range covers everything from lip enhancement to deep structural volumizing, and is distinguished from many competitor lines by using two different antioxidants — mannitol and sorbitol — matched to what each product grade is actually designed to do. This guide breaks down the full Stylage range, what sets its formulation apart, and what clinics should verify when sourcing it.
WHAT MAKES STYLAGE DIFFERENT: THE IPN-LIKE TECHNOLOGY
Laboratoires Vivacy introduced Stylage to the aesthetics market in 2008, developing it in collaboration with aesthetic medicine practitioners around a patented crosslinking method known as IPN-Like, short for Interpenetrated Polymer Network. Rather than crosslinking hyaluronic acid chains at a single density, IPN-Like combines highly crosslinked and lightly crosslinked HA within the same gel — the aim being a filler that holds its structural correction while still integrating smoothly into tissue.
The formulation also splits by function into two antioxidant systems. Filling and volumizing grades use mannitol, chosen for its resistance to mechanical breakdown under tissue movement. The Hydro and Hydromax skin-boosting products use sorbitol instead, selected to maximize moisture retention rather than structural resistance. That distinction — matching the antioxidant to the product’s job rather than using one formula across the entire range — is one of the more frequently cited technical differentiators between Stylage and competing HA lines.
THE FULL STYLAGE RANGE
Stylage S — The lightest gel in the range, designed for fine superficial lines, particularly around the eyes and perioral area where subtlety matters most.
Stylage M — A mid-density gel for moderate wrinkles and folds, one of the most commonly stocked products in the range for general facial rejuvenation.
Stylage L — A firmer gel for deeper wrinkles and folds, including nasolabial folds and marionette lines, where more structural correction is needed.
Stylage XL — The first product in Vivacy’s dedicated volumizing tier, used to restore lost volume in the cheeks, cheekbones, and overall facial contour.
Stylage XXL — The most volumizing product in the range, formulated for significant structural correction in areas like the cheeks, chin, and jawline.
Stylage Hydro — A skin-quality product focused on hydration rather than volume or line correction, formulated with sorbitol to support moisture retention and overall skin health.
Stylage Hydromax — Positioned as part of Vivacy’s mesotherapy range and distinct from Hydro, Hydromax is built around the brand’s Skin3 Complex to support cell renewal and improve skin quality over time. It is described as the brand’s flagship hydration product.
Stylage Special Lips — Formulated specifically for lip hydration, contour correction, and moderate volume, available in formulations without added anesthetic for practitioners who prefer that option.
Stylage Lips Plus — A more volumizing lip-specific product than Special Lips, designed for practitioners seeking a fuller result while maintaining a soft, adaptable feel in the tissue. Available only with a numbing agent formulated in.
Stylage Bi-Soft — A softer-feel presentation used in select markets, positioned for practitioners looking for a gentler tissue integration in specific treatment zones.
CHOOSING ACROSS THE RANGE
The practical way to navigate the Stylage line is to separate the decision into two questions: how much structural correction does the treatment area need, and is the goal correction or hydration.
For fine lines and early aging signs, Stylage S is the starting point. As correction needs deepen — moderate wrinkles, then deeper folds, then significant volume loss — the range moves through M, L, XL, and XXL in that order, each step formulated with a firmer gel for a more structural result.
For skin quality rather than line or volume correction, Hydro and Hydromax sit outside that structural ladder entirely, built on the sorbitol-based hydration formulation rather than the mannitol-based filling formulation.
For lips specifically, Special Lips and Lips Plus offer two different intensities — hydration and contour versus more pronounced volume — allowing practitioners to match the product to how much change the patient is actually looking for.
Many clinics build a core Stylage protocol around three or four grades (typically M, L, one volumizing product, and one lip or hydration product) rather than stocking the full range, expanding as patient demand across specific treatment areas grows.
WHAT TO LOOK FOR WHEN SOURCING STYLAGE
Verifying a genuine Stylage product before committing to an order matters as much as choosing the right grade for a treatment. Before bringing on a new supplier, it is worth checking for:
Batch traceability — every unit should carry a batch number that can be checked against the product itself, not just the invoice.
Packaging integrity — intact seals, correct labeling, and box design consistent with what Laboratoires Vivacy publishes for the current product generation.
Storage conditions — confirmation that products have been kept within the manufacturer’s specified storage range throughout transit, not just at the point of sale.
Supply consistency — a source that can support recurring, clinic-level volume rather than one-off availability, since irregular supply is one of the most common reasons clinics end up switching sourcing partners mid-year.
FREQUENTLY ASKED QUESTIONS
What is Stylage made of?
Stylage is a range of hyaluronic acid dermal fillers manufactured by Laboratoires Vivacy in France, crosslinked using the brand’s patented IPN-Like technology and formulated with either mannitol or sorbitol as an antioxidant, depending on the product’s intended use.
What is the difference between Stylage and other hyaluronic acid fillers?
The main technical differentiator is IPN-Like crosslinking, which combines highly and lightly crosslinked hyaluronic acid in the same gel, along with a dual-antioxidant approach that matches mannitol to structural filling products and sorbitol to hydration-focused products like Hydro and Hydromax.
Which Stylage product is used for lips?
Stylage Special Lips and Stylage Lips Plus are the two lip-specific products in the range. Special Lips focuses on hydration and contour with a lighter feel, while Lips Plus is formulated for more pronounced volume.
How long do Stylage results typically last?
Duration varies by grade and by patient metabolism. Lighter formulations such as Hydro and Stylage M typically last around 6 to 9 months, while firmer volumizing grades such as L, XL, and XXL are generally associated with results lasting 12 to 18 months.
How can a clinic verify a Stylage supplier before ordering?
Check for batch-level traceability, intact and correctly labeled packaging consistent with the current product generation, confirmation that storage conditions were maintained through transit, and a track record of consistent supply rather than one-off availability.
