Achieving facial rejuvenation that seamlessly integrates with natural expression is a key goal in modern aesthetics. Patients increasingly seek treatments that soften wrinkles without resulting in a “frozen” or unnatural appearance, especially in highly mobile areas of the face. The Teosyal RHA® line of hyaluronic acid (HA) fillers, developed by Teoxane Laboratories and distributed by Revance Aesthetics, was specifically engineered to meet this challenge. Utilizing unique “Resilient Hyaluronic Acid” technology, these fillers are designed to adapt to facial dynamics. This article provides an introduction and comparison of the core products available to practitioners – Teosyal RHA® 2, RHA® 3, and RHA® 4 – clarifying their properties and applications.

Understanding the Science: What Makes RHA® Technology Different?

The foundation of the Teosyal RHA guide lies in understanding its core technology. RHA stands for Resilient Hyaluronic Acid. The manufacturing process is designed to:

• Preserve Natural HA Structure: Aims to better maintain the natural, long chains and mobile bonds inherent in hyaluronic acid, requiring less modification during the cross-linking process compared to some traditional HA manufacturing methods.
• Optimize Dynamic Properties: This results in gels characterized by exceptional “stretch” (the ability to deform and extend with facial movements like smiling or talking) and appropriate “strength” (the ability to resist stress and provide support even during movement).

The clinical significance of the RHA technology explained here is its ability to integrate smoothly and move synergistically with facial tissues. This allows for the correction of dynamic wrinkles and folds while maintaining a remarkably natural appearance during facial animation, making them ideal natural expression fillers.

Meet the Collection: Teosyal RHA® 2, RHA® 3, and RHA® 4

The RHA line offers a spectrum of products, each calibrated with different degrees of stretch and strength to suit varying clinical needs and injection depths. All formulations available in the US typically contain lidocaine for patient comfort.

A. Teosyal RHA® 2

• Position in Range: The most flexible formulation within this core group, offering the highest stretch.
• Properties: Designed for superficial to mid-dermal placement, integrating smoothly into areas requiring significant mobility.
• US FDA Approval: Indicated for the correction of moderate to severe dynamic facial wrinkles and folds (such as nasolabial folds) in adults aged 22 or older. Often utilized by practitioners for moderate dynamic lines, including perioral or radial cheek lines where flexibility is paramount (note indication specifics).
• Clinical Use: Ideal for treating dynamic lines where maximum adaptability to movement is needed. A key flexible HA filler option. Ensure reliable suppliers when seeking to buy RHA 2 wholesale.

B. Teosyal RHA® 3

• Position in Range: Offers a balanced profile, providing both good stretch and moderate dynamic strength.
• Properties: Suitable for injection into the mid-to-deep dermis. More supportive than RHA 2 while retaining excellent flexibility.
• US FDA Approval: Indicated for the correction of moderate to severe dynamic facial wrinkles and folds (such as nasolabial folds) in adults aged 22 or older. Widely used for moderate to deeper dynamic folds requiring both support and flexibility.
• Clinical Use: A versatile choice for common dynamic areas like moderate nasolabial folds or oral commissures. Consider trusted sources when deciding to order RHA 3 online.

C. Teosyal RHA® 4

• Position in Range: Provides the greatest dynamic strength and structural support within this trio, while still maintaining resilience.
• Properties: Designed for deep dermal to subcutaneous placement. Offers robust support that adapts to facial movement.
• US FDA Approval: Indicated for the correction of moderate to severe dynamic facial wrinkles and folds (such as nasolabial folds). Also approved for injection in the deep dermis to subcutaneous tissue for correction of moderate to severe dynamic folds, such as nasolabial folds, and dynamic areas such as cheeks and contours, in adults aged 22 or older.
• Clinical Use: Excellent for treating deeper dynamic folds that require more significant volume and structural support. Also well-suited for providing contour and volume in dynamic areas like the cheeks (Teosyal RHA 4 cheeks) where both support and movement are needed. A key product for dynamic facial contouring available when looking to buy RHA 4 filler B2B.

Comparative Overview & Product Selection Strategy

The Teosyal RHA 2, 3, and 4 products represent a graduated series, allowing practitioners to tailor treatment precisely:

• Spectrum: RHA 2 (Max Stretch/Lower Strength) → RHA 3 (Balanced Stretch/Strength) → RHA 4 (Moderate Stretch/Higher Strength).
• Selection Criteria:
  • Wrinkle/Fold Depth: Superficial/Moderate (RHA 2) → Moderate/Deep (RHA 3) → Deep/Volume Loss (RHA 4).
  • Area Dynamism: Areas with extreme mobility might favor RHA 2 or 3, while areas needing more structural support during movement benefit from RHA 4.
  • Volume Need: RHA 4 provides the most volumizing capacity within this group.
  • Injection Plane: Match the product to the intended anatomical depth (superficial/mid-dermis for RHA 2, mid-deep dermis for RHA 3, deep dermis/subcutaneous for RHA 4).

Administration Considerations for Dynamic Fillers

While based on HA principles, maximizing the benefit of RHA fillers involves attention to technique. Accurate placement within the intended tissue plane is key to allowing the filler to integrate and move naturally with surrounding structures. Overcorrection should be avoided, as the goal is natural enhancement that respects dynamics. Thorough patient assessment, including observing facial expressions, helps guide appropriate product choice and placement.

Safety Profile & Sourcing Authentic RHA® Fillers

As with all HA fillers, potential side effects include temporary bruising, swelling, redness, and tenderness. The unique dynamic properties require practitioners to understand how the product behaves post-injection. Vascular Occlusion (VO) remains the most significant serious risk associated with any dermal filler injection, necessitating thorough anatomical knowledge and safe injection practices.

Crucially, practitioners must consult the specific US Prescribing Information (IFU) provided by Revance Aesthetics for RHA 2, RHA 3, and RHA 4 before use. Ensuring you use authentic Teosyal RHA® products is vital for predictable performance and patient safety. Source only through authorized channels or reputable licensed suppliers like Health Supplies Plus, who guarantee genuine product integrity when you seek to buy Revance fillers online or order RHA fillers.

Conclusion: Embracing Dynamic Correction with Teosyal RHA®

The Teosyal RHA® collection offers a significant advancement for aesthetic practitioners aiming to correct wrinkles and folds while preserving natural facial expression. The unique Resilient Hyaluronic Acid technology provides an exceptional balance of stretch and strength. By understanding the graduated properties of RHA 2, RHA 3, and RHA 4, clinicians can select the ideal product to address specific dynamic concerns, from fine lines to deeper folds and facial contours. This innovative line represents a valuable tool for achieving highly natural, dynamic, and satisfying patient outcomes.
