Aureobasidium Pullulans Ferment

Aureobasidium pullulans ferment is derived from a naturally occurring yeast-like fungus. The ingredient is produced through fermentation, a process that extracts beneficial compounds (exopolymers) from the microorganism. These fermentation-derived compounds have been studied for their potential to support skin health through multiple pathways.In skincare formulations, it functions primarily as a skin conditioner, helping to maintain skin texture and hydration. The ingredient appears in a small proportion of skincare products, suggesting it remains relatively niche within the broader skincar…

The fermented exopolymers from Aureobasidium pullulans appear to work through multiple mechanisms. They demonstrate free radical scavenging capacity in laboratory settings, meaning they can chemically neutralise unstable molecules that damage skin cells. The ingredient also shows activity against certain enzymes (hyaluronidase, elastase, collagenase) that naturally break down structural proteins in the skin.Additionally, preliminary research suggests the ferment may influence NAD+ synthesis, a coenzyme central to cellular energy production. However, the extent to which these laboratory find…

Aureobasidium pullulans ferment is typically incorporated into serums, moisturisers, and treatment products rather than cleansers. Since it functions as a skin conditioner, it works best when left on the skin. Combine it with other evidence-backed ingredients (such as sunscreen for daytime use) to support a comprehensive skincare routine. There are no known specific usage restrictions; it can generally be used daily as part of your regular regimen.

Aureobasidium pullulans ferment is generally well-tolerated and has a low incidence of adverse reactions reported in cosmetic use. As with any ingredient, those with known sensitivities to fermented ingredients or yeast-derived products should perform a patch test before widespread application.
