This webinar will teach the dynamic rheology of the Teosyal RHA line of dermal fillers and how it is the only filler on the market designed to respect natural facial movements.

In this webinar, we will discuss the differences between the stable and dynamic regions of the face. We will review the signs of aging and facial anatomy. We will also focus on the new technologies that had been introduced by Teoxane (Clarion) company in making more dynamic fillers that can integrate with the texture and mobility of the tissue. Combination of traditional filers with more dynamic fillers will be discussed as well.

Highlights

Nonmodified HA is highly dynamic but easily degraded in the skin. It has been made of long HA chains in a 3D mobile network that maintains tissue architecture, volume, and hydration. On the other hand, monophasic cohesive gels are rigid in structure. Shortening of the HA chains during the manufacturing process leads to more BDDE needed to obtain desired gel structure and a rigid structure.

Teoxane’s crosslinking strategies include optimized crosslinking conditions to preserve HA natural size and favorize natural bonding. It requires lower BDDE content (2-4%) to achieve optimal viscoelasticity/flexibility in comparison to classic crosslinking technology that damages hydrogel viscoelastic properties, shortens HA chain, and requires a high degree of modification (crosslinker about 5-10%) which leads to a more rigid structure. Preserved network technology preserves HA natural long chain, enhances hydrogel viscoelastic properties, and requires a low degree of modification (crosslinker about 2-4%) so it will have a dynamic structure.

In comparison to its competitors, the mechanical resistance of the TEOSYAL RHA product increases with the product indications from RHA1 to RHA4. There is no correlation between G’ and the filler mechanical resistance that challenges the common belief that G’ reflects the gel hardness and projection capacity.

Strength (mechanical endurance and resilience) is the ability of a gel to maintain its viscoelastic properties over a wide domain of stresses and deformations while the stretch (malleability and adaptability) is the ability of a gel to deform upon application of stress (Creep test). TEOSYAL RHA product range is adapted to FACIAL DYNAMISM for NATURAL-LOOKING RESULTS. TEOSYAL RHAs have rationally balanced strength and stretch scores matching the product indication.

The TEOXANE approach is a method based on 3 pillars, Anatomy, Techniques, and products. Anatomy needs to bring you tips and tricks to make your injection safer. The most dangerous areas published are Glabella, nose, perialar, temple, infraorbital, and lips. We will teach you anatomical advice and tips and tricks about each area to inject safely. Appropriate product selection is really hard to give you an algorithm but we will try to show you which products we use for specific goals.

The multilayering technique is used to compensate for the volume loss in two layers where we use 2 volumizers for 1 solution. You can’t do this technique in one plane with one product because if you inject deep, to get the same lifting effect, you will have to inject more, so more complication and cost. Also, if you inject only superficial, you will have the risk to get bumps and rigidity, moreover, if you use classical products.
