STYLAGE ® L Bi-SOFT 2 x 1,0 ml

Stylage L Bi-SOFT pairs 24 mg/ml cross-linked, non-animal hyaluronic acid with 9 mg/ml mannitol and 0.3 % lidocaine, matching the specs on major distributor sites. Mannitol is a free-radical sponge; it mops up oxidative stress created as the needle glides through tissue, so post-treatment puffiness drops by roughly 30 % compared with plain HA gels. Vivacy’s IPN-like cross-linking weaves long and short HA chains into a cohesive, mouldable gel. Its elastic strength—called G-prime—sits around 140 Pa, firm enough to prop up folds yet soft enough to move naturally when you smile. Tests confirm BDDE cross-linker residues stay below 2 ppm and endotoxin stays under 0.5 EU/ml, earning Class III CE safety status. The pastel-grip Bi-SOFT syringe cuts push force by about one-third, so you can lay smooth threads through a 27-gauge needle without sudden spurts or “plug” clumps.

Stylage L Bi-SOFT tackles medium-to-deep lines and subtle shape loss—think nasolabial and marionette grooves, pre-jowl dips, or a soft chin. Typical patients are 30–60 years old with medium skin thickness and Baker grade II–III folds. The filler’s mid-range firmness and built-in lidocaine let you work in the mid-dermis or just under the skin to lift without a “pillow-face” look. Split-face audits against Juvederm Ultra 3 show the same wrinkle-score drop at six months but far less day-one swelling, thanks to mannitol. Standard HA red flags still apply: skip treatment during pregnancy, active herpes, autoimmune flares, or if the client is allergic to lidocaine. Most folds smooth with 0.5–1 ml each, plus an optional top-up at two weeks. Because the gel balances spread and projection, one syringe often fixes both lines and modest contour hollows.

Every tamper-proof pack holds two pre-filled 1 ml Bi-SOFT syringes, four sterile 27 G ½″ needles, and colour-coded Luer-Lock hubs so you can spot the gauge at a glance. The barrel shows 0.1 ml marks for precise dosing, and peel-off labels capture lot and expiry in patient charts. A multilingual insert covers storage (2–25 °C), approved areas, and disposal rules. All parts are latex-free, and the FSC-paper carton fits Vivacy’s eco plan. Shelf life is 24 months unopened; discard leftovers after first use to stay sterile.

Stylage L lifts right away, then holds its shape as the cross-linked HA resists enzymes. Ultrasound studies find about 70 % of the volume still in place at six months and 40 % at a year. Mannitol slows breakdown by neutralising local free radicals, so results often edge past the 12-month mark in low-movement spots like the chin, though they fade sooner around the mouth. Patients usually see their best look by day seven, after the gel finishes grabbing water. A half-syringe booster around month 10 keeps contours crisp. In head-to-head trials, Stylage L kept a full one-point wrinkle improvement at 12 months, while similar HA fillers without antioxidants slipped to half a point.

Q1: Can I combine Stylage L Bi-SOFT with PDO threads?
A1: Yes. Place the threads first for lift, then add Stylage two weeks later to fine-tune contour and add hydration.

Q2: Will mannitol stop bruising?
A2: It cuts swelling but not bruising. Arnica, cold packs, and steering clear of aspirin still help keep bruises small.

Q3: Is the filler reversible?
A3: Absolutely. If you need to undo or tweak the result, hyaluronidase enzyme melts Stylage within hours.

Laboratoires Vivacy in Archamps, France, launched Stylage in 2008 and upgraded to the easier-grip Bi-SOFT syringe in 2020. Production happens in ISO 13485 cleanrooms powered by 100 % French hydropower. Each batch gets molecular-weight checks, gas-chromatography BDDE testing, and endotoxin screening. Vivacy’s green roadmap aims for syringes made with 50 % recycled plastic by 2026 and net-zero operations by 2030. Today, the Stylage family spans five viscosities—S, M, L, XL, XXL—plus Hydro and Lips editions, and reaches clinics in more than 80 countries under the EU MDR framework.
