Sisthaema Duo Longevity (2 ml + 2 ml) is a two-step injectable set made up of two complementary medical devices, Sisthaema Hevo +T and Sisthaema Seiquence, created for the comprehensive rebuilding of the quality, density and firmness of facial skin. The set meets the needs of skin requiring multi-level regeneration, affected by volume loss, laxity and oxidative stress. It is an aesthetic medicine solution based on a skin longevity strategy.
Two-step repair and replenishment model
Sisthaema Duo Longevity combines two devices with complementary action. Sisthaema Seiquence delivers the substrates needed for the regeneration and rebuilding of protein structures, while Sisthaema Hevo T focuses on optimising the tissue environment, improving hydration and cytoprotection. This combination matches the physiology of repair processes, in which effective regeneration requires a stable microenvironment and the availability of building blocks.
Skin longevity strategy
The Sisthaema Duo Longevity concept goes beyond the immediate visual effect and focuses on the long-term optimisation of tissue quality and biologically driven volume restoration. Through the synergy of fragmented hyaluronic acid, trehalose and a complex of nine amino acids, the set supports collagenogenesis and the stability of the extracellular matrix. The result is a strengthening of the supporting structures and stabilisation of the soft tissues.
Effects of use
Using the set delivers a long-term improvement in skin density, elasticity and firmness. There is a visible natural restoration of facial volume and projection, along with a reduction of signs of fatigue and the effects of oxidative stress. The set works well in repair and replenishment treatments for people expecting results beyond classic biorevitalisation.
