Aureobasidium Pullulans Ferment
What is Aureobasidium Pullulans Ferment?
Aureobasidium Pullulans Ferment originates from the controlled fermentation of Aureobasidium pullulans, a dark-pigmented yeast. This biotechnological process produces a cell-free filtrate containing pullulan polysaccharide, beta-glucans, and various metabolites. Primarily featured in skincare products like serums and creams, it acts as a multifunctional conditioning agent. In formulations, it creates a thin, flexible film over the skin to minimize transepidermal water loss while permitting normal respiration. Its humectant qualities draw moisture into the stratum corneum, fostering hydration. The ingredient bolsters skin suppleness and smoothness by interacting with the surface lipids and proteins, aiding barrier integrity without residue. Derived naturally via microbial fermentation, it suits clean beauty preferences in hydrating cosmetics.
