Sirtuin Hyaluronic Serum combines the moisturizing, firming action of hyaluronic acid with the anti-aging action of sirtuin. The hyaluronic acid it contains, creates a moisturizing film, reducing the transdermal water loss. It contributes to the structural integrity of the extracellular matrix of the skin, forming a strong grid supporting the collagen and elastin fibers. Sirtuin, a saccharomycetes of biomimetic activity of the Sirtuin proteins, is characterized as the longevity gene due to its action mechanism (cell “self-purification”)
