Kysse), 171 (R. Volyme), and 271 (R. Defyne) Pa, respectively (Figure 1 and Table 1).
HA fillers produced with OBT technology demonstrated the highest xStrains (flexibility), comprising 1,442%, 908%, 930%, and 761% for R. Refyne, R. Kysse, R. Volyme, and R. Defyne, respectively. NASHA formulations showed xStrains of 7% (Restylane), 19% (R. Silk), and 17% (R. Lyft) (Figure 2 and Table 1).
The combined characteristics of each HA filler in terms of strength/firmness (G') and flexibility (xStrain) are plotted in Figure 3.
