Description
Teoxane Teosyal® RHA 2
Teoxane Teosyal® RHA 2 is a resorbable hyaluronic acid–based dermal filler developed using Teoxane’s proprietary Resilient Hyaluronic Acid (RHA®) technology. This manufacturing process is designed to preserve the natural HA chain length while introducing controlled cross-linking, allowing the gel to adapt to dynamic facial movements while maintaining tissue support .
Teosyal® RHA 2 is intended for the correction of superficial to moderate facial wrinkles and fine lines, particularly in areas subject to frequent expression. The formulation consists of non-animal stabilised hyaluronic acid and includes lidocaine hydrochloride to enhance patient comfort during injection . Compared with higher-viscosity fillers in the RHA range, RHA 2 exhibits a softer rheological profile, supporting smooth tissue integration and flexibility. The product is supplied sterile in prefilled syringes and is intended exclusively for use by qualified medical professionals in accordance with the manufacturer’s Instructions for Use (IFU).
What Teosyal® RHA 2 Is Similar To
Teosyal® RHA 2 belongs to the category of soft, dynamic hyaluronic acid dermal fillers designed for superficial wrinkle correction. Within the Teosyal RHA portfolio, it is positioned below RHA 3 and RHA 4, offering lower gel firmness and greater flexibility for areas with high mobility.
For clinical orientation, RHA 2 may be compared with products such as Restylane® Refyne or Belotero® Balance, which are also formulated to integrate smoothly into superficial dermal layers while accommodating facial movement. Differences exist in HA concentration, cross-linking technology, and rheological behaviour, which influence durability and tissue response. RHA® technology focuses on resilience during repeated expression rather than lift or volumisation.
This comparison is provided for clinical orientation only and does not imply interchangeability.

FAQ
What type of filler is Teosyal® RHA 2?
Teosyal® RHA 2 is a resorbable hyaluronic acid dermal filler developed using RHA® technology. It is designed to correct fine to moderate wrinkles while adapting to facial movement. The formulation includes lidocaine to improve patient comfort during injection.
How does RHA® technology affect filler performance?
RHA® technology preserves longer HA chains during cross-linking, supporting elasticity and resilience under dynamic facial stress. This helps the filler move with facial expressions rather than resisting them, which is particularly relevant in superficial and mobile areas .
Does Teosyal® RHA 2 contain lidocaine?
Yes. Teosyal® RHA 2 contains lidocaine hydrochloride to reduce discomfort during injection. The manufacturer does not publicly specify the exact percentage in available documentation .
How long do results last?
The manufacturer does not specify a fixed longevity range in the IFU. Duration of effect varies based on individual metabolism, treatment area, and technique, and should be evaluated within a clinical consultation.
Is Teosyal® RHA 2 suitable for lip treatments?
The IFU does not explicitly list lips as a treatment area. Any use in specific anatomical regions must follow professional judgement and official manufacturer guidance. Products should not be considered interchangeable without appropriate training.
