THE DUAL POWER
OF BIOSTIMULATION AND CORRECTION
Hyal-System DUO is a hyaluronic acid hydrogel formulation based on the proprietary MU.C.H. (Multi-Crosslinked Hyaluronan)
Technology, that combines two types of HA for long-term correction and filling of medium to deep wrinkles, thereby restoring tissue
density1: 25% HA ACP and 75% HA cross-linked with BDDE. It means that Mu.C.H. technology requires 25% less BDDE with respect
to standard crosslinking2.
It improves skin firmness and elasticity, giving a rejuvenating effect to the skin8
As a result, the skin is firm, elastic and rejuvenated.

BIOSTIMULATION for a progressive and sustained rejuvenation from within
Biostimulation promoted by HA increases collagen/ECM in a progressive and sustained way, ensuring long-lasting aesthetic results.3
To investigate the efficacy of HA-based dual injectable (BDDE and auto-crosslinked HA) in collagen density variations, a retrospective study on 6 female patients (age range 34â56) treated in a single session, at baseline (T0), was conducted.3

OCT collagen density levels at different time intervals; histograms show an increase of collagen density up to 3 months (T3) as compared to T0, after a single session of HA-based injectable, performed in a single session at T0.Â
§Data available on five out six patientsâone patient missed follow-up at 2 months (T2).Â
The term BIOSTIMULATION indicates slow and sustained neo-collagenesis and ECM deposition after intradermal injection aimed to optimize skin physiology and achieve an aesthetic improvement3,4
Subsequent sessions of HA-biostimulatory treatment progressively increase the ECM3
Expected progressive increase in ECM with subsequent sessions of crosslinked HA injections as hypothesized based on the current concept of biostimulation.  Blue arrows indicate the difference in extracellular matrix content after each session3.

LMW-HA (200 kDa) provides a microenvironment suitable to facilitate the physiological homeostasis of ECM.5
