A Unique Combination of Stretch and Dynamic Strength

Resilience is the ability of a gel to maintain its integrity after stretching, bending, and being compressed, allowing the RHA® Collection to adapt to repetitive stress of facial movement.

Stretch (%/s)

Stretch is the ability of the gel to deform (extend) and adapt to dynamic facial movement. The “Stretch Score” reflects the ability of the gel to deform without disruption when subjected to continuous pressure.

Dynamic Strength (Pa2)

The “Dynamic Strength Score” characterizes the ability of a gel to maintain its physical integrity and gel characteristics over a wide range of stress or deformation values.
