Description
Teoxane Teosyal® RHA 1 is a sterile, resorbable hyaluronic acid–based dermal filler developed for the correction of superficial facial wrinkles and fine dynamic lines. It forms part of the Teosyal® RHA (Resilient Hyaluronic Acid) range, which is designed to adapt to facial movement while maintaining dermal support. The formulation is based on non-animal, cross-linked hyaluronic acid produced using Teoxane’s Preserved Network Technology, intended to preserve the natural structure of the HA chains during manufacturing .
Teosyal® RHA 1 contains lidocaine hydrochloride to improve patient comfort during injection. The gel is engineered for superficial dermal placement and is indicated for professional aesthetic use only. Its clinical performance depends on patient factors, injection technique, and adherence to the manufacturer’s Instructions for Use (IFU). Administration must be performed exclusively by qualified medical professionals in accordance with regulatory and manufacturer guidance.
What Teosyal® RHA 1 Is Similar To
Teosyal® RHA 1 belongs to the category of hyaluronic acid dermal fillers indicated for superficial wrinkles and fine lines. Within the Teosyal portfolio, it represents the lightest filler in the RHA range, positioned for subtle correction in areas affected by early signs of ageing.
For clinical orientation, Teosyal® RHA 1 may be compared with products such as Juvederm® Volbella or Restylane® Refyne, which are also designed for fine lines and areas subject to facial movement. These products share a similar HA-based mechanism of action but differ in cross-linking technology, gel elasticity, and tissue integration characteristics. Teosyal® RHA 1 incorporates resilient hyaluronic acid technology and includes lidocaine within the formulation, whereas some alternatives may differ in anaesthetic inclusion or gel rheology.
