Saccharomyces Cerevisiae (Yeast) Extract

While there are many different yeast extracts used in skincare, this one is here to provide vegan collagen. It is one component of a rapid delivery skin plumping system. In this system, yeast extract combines with sodium chondroitin sulfate, hyaluronic acid, and phospholipids to noticably lift skin and plump the appearance of fine lines and wrinkles.

To create this skin plumping system, vegan collagen is derived through biotechnology from saccharomyces cerevisiae yeast. The dehydrated collagen is then loaded into a nourishing phospholipid base along with hyaluronic acid and chondroitin. This active-loaded delivery system strives to build a “scaffold” in the skin mimicking its own collegen structure. This biomimetic structure provides support and noticable volume instantly.1

The dehydrated nature of the nanoparticles allows them to penetrate skin quickly and “swell rapidly forming a reconstituted human tissue matrix” in the skin.2 “The chondroitin sulfate and hyaluronic acid crosslink with the collagen, giving the matrix a distinct 3-Dimensional structure; creating a firm, supple aesthetic coupled with the sensation of rapid firming.”

NanoVesicular delivery systems vs. Liposomes

They have some things in common, but the two differ slightly.

Like the system we’ve discussed here, liposomes are also used to aid in delivery of actives. In order to form liposomes, actives are loaded inside phospholipid spheres. These fragile spheres require suspension in a aqueous base in order to remain intact.

This system differs from liposomal systems in that it is water-free. It goes by the name NanoVector or NanoVesicular3, which simply means an active loaded in a nanosized pocket. These systems disperse dehydrated nanoparticles in a phospholipid base without the aqueous input, thereby optimizing their application in anhydrous (water-free) systems.
