Saccharomyces Ferment

Saccharomyces Ferment is a yeast-derived ingredient created through the fermentation of Saccharomyces cerevisiae (baker's yeast). During fermentation, the yeast cells break down and release bioactive compounds including amino acids, polysaccharides, and antioxidants that can be used in skincare formulations.In skincare, it functions primarily as a skin conditioner, helping to improve skin texture and support the skin's natural moisture balance. The fermentation process creates compounds that may offer antioxidant benefits, potentially helping to protect skin from environmental stressors.

Saccharomyces Ferment works through multiple pathways. The fermented yeast contains compounds that activate the skin's own antioxidant defence systems, particularly pathways like Nrf2/HO-1 signalling. This helps the skin neutralise reactive oxygen species (free radicals) that accumulate from UV exposure and environmental damage.Additionally, the ingredient's amino acids and polysaccharides support the proteins that make up your skin barrier and maintain moisture. This is particularly relevant after UV damage or barrier stress, where these structural proteins become depleted.

Saccharomyces Ferment is typically used in serums, essences, and hydrating products. It works well in layered routines and pairs effectively with other hydrating or barrier-supporting ingredients. Because fermented ingredients are often included at modest concentrations (under 1% in most products), results tend to build gradually with consistent use rather than delivering immediate changes.

Saccharomyces Ferment is generally well-tolerated by most skin types. As with any fermented ingredient, individuals with yeast sensitivities or fungal acne concerns should patch-test first, though the fermentation process typically eliminates viable yeast cells.
