WHAT IS TEOSYAL®?
Teosyal® is a premium line of cross-linked and non-cross-linked hyaluronic acid (HA) injectables designed to restore volume, smooth deep wrinkles, hydrate skin quality, and redefine facial contours.
Unlike traditional rigid dermal fillers that sit heavy under the skin, Teosyal’s patented RHA® technology preserves the long chains of natural hyaluronic acid. This allows the gel to stretch and recoil seamlessly with your facial expressions whether you are smiling, laughing, or talking.
Rather than creating artificial volume, Teosyal® integrates smoothly into your dermal layers to respect your natural facial dynamics.
WHAT IS HYALURONIC ACID?
Hyaluronic acid (HA) is a naturally occurring glycosaminoglycan found throughout the skin’s extracellular matrix. It acts as a bio-sponge, holding up to 1,000 times its weight in water to maintain skin hydration, elasticity, and volume.
As we age, our natural HA reserves deplete by approximately 1% every year, leading to facial volume loss, under-eye hollowing, and fine lines. Teosyal® replenishes lost HA while supporting skin hydration and elasticity over time.
THE TEOSYAL® VARIANT PRODUCT RANGE
To deliver bespoke treatments for different anatomical layers, TEOXANE designed specialized product lines under the Teosyal® umbrella:
Product Variant | Primary Indication | Key Properties |
Teosyal PureSense Redensity I | Face, neck, and décolletage rejuvenation | Non-cross-linked HA combined with 8 amino acids, 3 antioxidants, and minerals to boost skin radiance and deep hydration. |
Teosyal PureSense Redensity II | Tear trough & under-eye dark circles | Formulated specifically for the delicate eye area with low hygroscopicity to minimize post-treatment puffiness. |
Teosyal RHA® 1 | Superficial fine lines & neck wrinkles | Ultra-light dynamic gel for subtle, fine line smoothing in high-movement areas. |
Teosyal RHA® 2 & RHA® 3 | Nasolabial folds, lip borders & Marionette lines | Medium-density gels designed for moderate-to-deep dynamic wrinkles and soft lip volume. |
Teosyal RHA® 4 & Ultra Deep | Cheekbones, jawline & structural contours | High-density viscoelastic gel designed to restore deep facial volume and structural support. |
Teosyal Kiss / RHA® Kiss | Lip augmentation & perioral reshaping | Specifically engineered for high-mobility lip tissue to define borders and enhance fullness. |
ADVANCED RHA® DYNAMIC TECHNOLOGY
The patented RHA® (Resilient Hyaluronic Acid) method preserves the long chains of natural hyaluronic acid by using lower levels of chemical cross-linking (BDDE). This gives Teosyal® fillers exceptional properties:
- High Stretchability: Flexes naturally with hyper-dynamic facial muscles.
- Tissue Integration: Blends into dermal layers without lumpiness or visible edges.
- Low Water Swelling: Specialized formulations like Redensity II resist excessive water absorption, reducing post-injection edema.
As the HA gel gradually breaks down over time, it naturally dissolves into water and carbon dioxide before being harmlessly absorbed by the body.
MECHANISM OF ACTION & TARGET AREAS
Once injected into the dermis, subcutaneous, or supraperiosteal layers, Teosyal®:
- Immediate Volume Restoration: Fills structural hollows and smooths surface wrinkles instantly.
- Dynamic Flexibility: Stretches with facial expressions without altering your natural movement.
- Hydro-Balancing: Draws bio-available water into the tissue matrix for long-term radiance.

Frequently Asked Questions
Results are visible immediately post-treatment, with final tissue integration softening beautifully over 7–14 days.
Depending on the variant and area treated, results typically last 9 to 18 months.
Redensity II is specifically designed with low water retention properties, making it significantly less likely to cause under-eye puffiness compared to standard dermal fillers.
Downtime is minimal. Mild redness or swelling may occur but usually subsides within 24 to 48 hours.
