The Preserved Network Technology

The first* resilient hyaluronic acid (HA) range specifically designed to accompany facial dynamics

Preserved Network

To naturally integrate into facial structures, an HA filler has to be able to resist pressure and seamlessly follow facial TEOSYAL RHA®** is the first* range movements of HA fillers with rheological properties specifically designed to follow the expression of the face. It results from a unique and innovative technology that better preserves the natural chains of the HA molecules1 to create a gel that mimics the natural HA within our skin.

The TEOSYAL RHA® portfolio of dermal fillers provides a selection of HA gels that covers a range of aesthetic needs from superficial dynamic wrinkles, through volume in extended areas for correction of facial wrinkles and folds.

The clinical efficacy and safety of the products was highlighted in an 18-month comparative study2. The study looked at the immediate and long-term efficacy of the gel as well as patient satisfaction2. This award-winning filler works in synchronisation with facial expressions to provide a natural looking result, whilst remaining undetectable3.
