Saccharomyces/Soy Protein Ferment

Saccharomyces/Soy Protein Ferment is created by fermenting soy protein using Saccharomyces cerevisiae, a common baker's yeast. This fermentation process breaks down the soy proteins into smaller, more bioavailable components and can enhance certain beneficial compounds naturally present in soy, such as isoflavones.In skincare formulations, this ingredient functions primarily as a skin conditioning agent, helping to improve the feel and hydration status of the skin's surface.

The fermentation process used to create this ingredient breaks down soy proteins into smaller peptides and amino acids, which are thought to be more easily absorbed by or interact with the skin. This may enhance the ingredient's conditioning and potentially calming effects compared to unfermented soy.Soy contains isoflavones, plant-derived compounds that appear to have immunomodulatory properties—meaning they may help regulate inflammatory responses in skin tissue, though more human studies are needed to confirm this mechanism in topical application.

This ingredient is typically found as part of a broader skincare formulation rather than used in isolation. Apply products containing it as directed, usually morning and/or evening as part of your regular routine. It is generally well-suited to layering with other actives, though as with any new ingredient, introduce it gradually if you have sensitive skin.

Generally well-tolerated by most skin types. Those with soy allergies should avoid this ingredient, though topical exposure carries lower risk than ingestion.
