Description
Clinical Description
Stylage® XL Bi-SOFT without Lidocaine is a cross-linked hyaluronic acid dermal filler developed by Laboratoires VIVACY for the restoration of facial volume and correction of deep skin depressions. The product is formulated using non-animal stabilised hyaluronic acid (NASHA-type cross-linked hyaluronic acid) combined with mannitol, an antioxidant designed to help reduce free-radical degradation of hyaluronic acid following implantation.
The filler is intended for deep dermal or subcutaneous implantation by qualified healthcare professionals to restore volume in areas affected by age-related volume loss. According to manufacturer documentation, Stylage® XL is indicated for facial contouring and volumisation, particularly in areas requiring substantial structural support and projection.
The Bi-SOFT® injection delivery system is designed to provide improved ergonomics, precision, and control during administration. This version does not contain lidocaine and may be selected by practitioners when a lidocaine-free formulation is preferred.
What Stylage® XL Bi-SOFT without Lidocaine Is Similar To
Stylage® XL Bi-SOFT without Lidocaine belongs to the category of volumising hyaluronic acid dermal fillers designed for correction of significant facial volume loss. It may be compared with products such as Juvederm® Voluma®, Restylane® Lyft®, and other high-density cross-linked hyaluronic acid fillers intended for deep tissue support.
Like Juvederm® Voluma®, Stylage® XL is designed to restore facial contours and provide structural support in areas such as the cheeks and midface. Both products utilise cross-linked hyaluronic acid technology but differ in manufacturing processes, rheological properties, and formulation characteristics.
Compared with skin boosters such as Profhilo®, Stylage® XL is intended primarily for volumisation rather than hydration-focused bioremodelling. Profhilo® is generally used to improve skin quality, whereas Stylage® XL is specifically designed to restore lost facial volume.

FAQ
1. What is Stylage® XL Bi-SOFT without Lidocaine used for?
Stylage® XL Bi-SOFT without Lidocaine is a volumising hyaluronic acid dermal filler designed to restore facial volume and correct deep skin depressions. Manufacturer information indicates use in areas requiring structural support, such as the cheeks and facial contours affected by age-related volume loss.
2. Does Stylage® XL contain lidocaine?
No. This specific formulation is supplied without lidocaine. It contains cross-linked hyaluronic acid and mannitol but does not include an anaesthetic component. Practitioners who require a lidocaine-containing option should consult the wider Stylage® product range.
3. What is the role of mannitol in Stylage® XL?
Mannitol is included as an antioxidant. According to manufacturer information, it is intended to help reduce oxidative stress and limit free-radical-mediated degradation of hyaluronic acid after implantation, supporting the stability of the filler gel.
4. How is Stylage® XL different from skin boosters?
Stylage® XL is primarily designed for volumisation and contour restoration. Skin boosters such as Profhilo® are generally intended to improve hydration and skin quality rather than provide structural volume replacement. The products therefore serve different clinical objectives.
5. How long do results last?
The manufacturer does not provide a universal duration applicable to all patients. Longevity depends on treatment area, injection depth, individual metabolism, lifestyle factors, and practitioner technique. Expected persistence should be discussed during professional consultation and assessed on an individual basis.
