Developed by Laboratories VIVACY, this specialized formulation is engineered specifically for precise lip enhancement, contouring, and perioral volume restoration.

Key Features & Innovation

• The Bi-Flex® Delivery System: This represents a significant evolution from the previous Bi-SOFT® platform. While the core formulation remains identical, the rebranded Bi-Flex® syringe features updated ergonomics that deliver improved handling, enhanced injection precision, and greater safety.
• Patient Comfort: Co-formulated 0.3% lidocaine improves patient comfort during injection without requiring a separate, multi-step anesthetic process.

Advanced Formulation Technology

• IPN-Like Technology™: The gel incorporates two interlocked hyaluronic acid (HA) polymer networks. This design increases gel cohesivity and elasticity, allowing the filler to withstand the continuous movement of the lip area while maintaining a soft, natural feel.
• Targeted Concentration: At 18.5mg/g of cross-linked HA, the formula balances noticeable volume enhancement with precise contour definition.

STYLAGE® SPECIAL LIPS BI-FLEX® with Lidocaine injection is intended for use by licensed aesthetic professionals experienced in soft-tissue augmentation. Common indications include:

• Lip volume enhancement and contour definition
• Correction of age-related volume loss affecting lip fullness and shape
• Vermillion border definition and philtrum column enhancement
• Perioral line correction and lip contour refinement

STYLAGE® SPECIAL LIPS BI-FLEX® with Lidocaine is particularly suited to multi-layer lip protocols, either as a standalone treatment or alongside higher-volume fillers for comprehensive lip rejuvenation. Because this formulation is designed for the precise lip treatment area, it is not intended for deep volume restoration in other facial regions. Treatment planning should consider the patient’s skin condition, lip anatomy, skin type, and overall suitability.

Cross-linked hyaluronic acid integrates into lip tissue and attracts water molecules, producing an immediate volumizing and defining effect that enhances lip contour, shape, and fullness. IPN-Like Technology™ features two interlocked hyaluronic acid polymer networks that improve gel cohesivity and elasticity, helping the filler resist deformation caused by continuous lip movement and supporting lasting volume retention and shape definition.

Treatment duration varies according to factors such as skin type, treatment area, lifestyle habits, and individual patient characteristics. The co-formulated 0.3% lidocaine provides localized anesthetic action during injection, improving patient comfort in the sensitive lip treatment area.

If correction or reversal is required, the cross-linked hyaluronic acid gel can be dissolved using hyaluronidase.

STYLAGE® SPECIAL LIPS BI-FLEX® with Lidocaine injection should only be performed by trained medical professionals experienced in lip anatomy and soft-tissue augmentation. Common injection sites include the lip body, vermillion border, and philtrum columns. Following treatment, patients should avoid excessive sun exposure until redness and swelling resolve, and minimize unnecessary pressure on treated areas. Bruising at the injection site may occur and typically resolves within a few days.

Common Side Effects

Common post-treatment reactions in the lips treatment area include swelling, redness, tenderness, and bruising at the injection site. These effects are generally temporary and typically resolve within a few days, though recovery may vary depending on the treatment area and factors such as skin type.

Serious Adverse Events

Although uncommon, serious complications may occur, including vascular occlusion, skin necrosis, and visual disturbance. Practitioners should be trained to recognize and manage these events according to established emergency protocols, including the appropriate use of hyaluronidase. Patients should be screened for hypersensitivity to hyaluronic acid and amide-type anesthetics, as well as for active infection in the treatment area, before treatment. Refer to the complete IFU for comprehensive safety information.
