Resilient hyaluronic acid (RHA), the latest dermal filler range launched in Australia, is changing the game in facial aesthetics. Teoxane Laboratories, the developers of RHA, have considered beauty in a dynamic dimension. A filler that can adapt to the dynamic movements of the face is the answer to a natural looking result.

The new RHA filler range is designed to support the skin in every move while being undetectable, as well as helping to preserve the vitality and softness of the face.

Don't want to look like you've had work done?

Many people considering dermal fillers for the first time are often daunted by the prospect of appearing swollen, lumpy or looking like they've had "work done". With the latest in dermal filler development , gone are the days of the "pillow face" appearance! Although there are a variety of ingredients contained within dermal fillers, hyaluronic acid is one of the most commonly found ingredients in dermal fillers here is Australia. Hyaluronic acid fillers belong to the class of temporary biodegradable fillers. Given that hyaluronic acid is a natural substance present in human skin, fillers consisting of hyaluronic acid have a very high safety profile.

Enzymes in the human body are involved in the process of natural hyaluron turn-over in the skin and these enzymes will also break down the hyaluron in dermal filler, accounting for their temporary and biodegradable nature. For dermal filler manufacturers, it is a race to research and develop hyaluronic acid gels that are more resilient, last longer in the skin, but also maintain a soft natural appearance.

What makes Teoxane's RHA filler so different?

The answer lies in the rheological properties of the gel itself. The substance that makes up a dermal filler is in the form of a gel consisting of chains of hyaluronic acid (HA). The HA chains are subject to various processes in the laboratory, such as cross-linking, in order to give them certain properties.  Highly cross-linked gels are more resistant to enzymatic break down and last longer in the skin, however, high levels of cross-linking also make the filler firmer, more palpable and more prone to clumping in the skin. Although this is an over-simplification, it can be seen that development of a dermal filler with the perfect elasticity, viscosity and resilience to achieve a natural, yet long-lasting results is of utmost importance.

According to Teoxane Laboratories, their RHA range uses a patented method of preserving long HA chains during the manufacturing process, resulting in unique properties that permit their use in mobile areas of the face. The complete integration of the product in the dermis allows for the preservation of natural  facial movements, while at the same time producing tissue restoration and rejuvenation effects.

The patented technology in the  RHA dermal filler range produces a gel consisting of long HA chains stabilised by natural and mobile interactions, requiring a low cross-linked rate which leads to a more dynamic and resilient HA gel with reduced swelling and side effects.

Why should you consider Resilient HA dermal filler?

Resilient hyaluronic acid differs from other dermal fillers in its ability to spring back into its original form after being stretched or compressed. This is an ideal property as it is able to soften and fill out facial hollows and wrinkles and can enhance facial features while preserving normal facial expression. As it integrates with the skin's tissues it moves dynamically with facial movement and expression achieving a natural looking result that is not lumpy or obvious.

In which areas of the face is RHA filler useful?

RHA is so sophisticated it can be used in all areas of the face. The RHA range of filler comes in four different intensities based mainly on the concentration of HA in the gel. This choice allows RHA to be used on different areas of the face for differing depths of wrinkles or hollows. They are suitable for the most mobile areas of the face - for lines around the mouth, in the lips, cheeks, smile lines etc

How is RHA dermal filler treatment performed?

After a thorough consultation with me, I assess your areas of concern and  plan which RHA filler will give you the best results. The areas to be treated are prepared with a topical local anaesthetic gel prior to treatment. The RHA filler range also contains lidocaine , a local anaesthetic, to make the procedure as comfortable as possible for you. Depending on the area of the face to be treated , various techniques are used to inject the filler into the site. Most treatments take less than 30 minutes. Your results are instant and swelling with this new range of RHA filler is limited. Many of my patients go straight back to work after their procedure.

The RHA range is a TGA-approved dermal filler and has been rigorously tested prior to approval here in Australia. Your result will also be dependent on the qualifications,  knowledge and experience of the person performing your injections. Here is some advice from the TGA regarding "things to consider before undergoing procedures involving dermal fillers".

The Doctor's Opinion

I love using a product that gives instant and natural aesthetic results with very limited down-time. In my opinion, being able to see the results without feeling the filler in the skin - that's truly the ultimate aim of a great dermal filler. The Teosyal RHA range certainly fits the bill in this regard.
