Resilient Hyaluronic Acid®

About Hyaluronic Acid

TEOSYAL  RHA®, designed for facial dynamics 

When a dermal filler is injected into the face, it is subjected to a wide range of facial movements and pressures that occur when you express emotions, talk, eat….1

These can alter the properties and behaviour of the filler. 

Fillers need to be designed with facial dynamics in mind, so they seamlessly follow our facial expressions and resist deformations and pressures from skin layers for natural and long-lasting results.2,3

This is where Teoxane comes in. 

Teoxane is the first aesthetics company to put facial movement at the heart of its product design and testing, with its new range of dynamic premium fillers*, Teosyal RHA® by Teoxane. 

This is the first collection of dermal fillers* indicated for dynamic wrinkles and folds and adapted to the mobile regions of the face.

TEOSYAL RHA® vs HA: what’s the difference? 

What sets TEOSYAL RHA® apart




Due to a unique and bespoke manufacturing process, the preserved network technology1, TEOSYAL RHA® has longer chains and less rigid crosslinks than the modified HA usually found in dermal fillers.1 

This mobile structure, closer to natural HA than other modified HA found in traditional fillers, confers unique dynamic properties to the TEOSYAL RHA® fillers4


  • SUPPLENESS, to adapt faster to facial movement and preserve natural facial expressions 
  • RESISTANCE, to repeatedly bounce back from deep muscle pressures for long-lasting volume 
  • STRUCTURAL INTEGRITY, to withstand facial stresses without fragmenting for predictable results with no irregularities.
TEOSYAL RHA®  unique dynamic properties

TEOSYAL RHA® fillers seamlessly follow the movement of the face and enhances individual's unique natural expressions without erasing what makes them who they are.2,4

The versatility of the TEOSYAL RHA® range 

Each filler within the TEOSYAL RHA® line (RHA® 1, RHA® 2, RHA® 3, RHA® 4 or RHA KISS®) benefits from a unique combination of suppleness and resistance, to meet the specific aesthetic needs of different dynamic facial regions.1 

From one of the supplest fillers on the market (RHA® 1) 1** for superficial dynamic wrinkle correction 

To one of the most resistant volumizers on the market (RHA® 4) 1*** for volume restoration and deep facial wrinkle and folds. 

TEOSYAL RHA® line (RHA® 1, RHA® 2, RHA® 3, RHA® 4 or RHA KISS®)

The versatility of the TEOSYAL RHA® line allows practitioners to confidently inject the right product following Teoxane ATP approach to provide natural, tailored results for each patient.4

The clinical benefits of TEOSYAL RHA® 

The RHA® range clinical efficacy and safety were demonstrated in an 12-month comparative study5**** (up to 18 months for RHA®2, RHA® 3 and RHA® 44*****). 

These studies demonstrated excellent immediate and long-lasting efficacy. It also highlighted the increased satisfaction of both patients and practitioners with results vs other commercially available fillers used, as well as the ease of injection and improved product positioning experienced by practitioners 4,5

These award-winning fillers move in harmony with facial expressions to provide a natural looking result, whilst remaining undetectable.4,5


An innovative crosslinking technique 

Classical method6

During conventional filler manufacturing processes, the natural chains and bonds of HA are fragmented due to these harsh conditions. These chains must then be brought back together with rigid crosslinks, creating a brittle structure that no longer flows with movement.1

Classical Method

Preserved Network

Inspired by human biology, Teoxane has developed the unique “preserved network technology”1 that, as its name suggests, better preserves the long chains and mobile bonds of natural hyaluronic acid, thus allowing minimal modification.1
