Hydrolyzed Aspergillus/Saccharomyces/Rice Ferment Lees Extract is a unique ingredient derived from the fermentation of rice by two types of microorganisms: Aspergillus and Saccharomyces. This ingredient is also known by other names, such as Rice Ferment Filtrate or simply Rice Ferment Extract. Chemically, it is a hydrolysate, which means it has been broken down into smaller components through a process called hydrolysis, making it easier for the skin to absorb.
The history of using rice fermentation in skincare dates back centuries, particularly in Asian cultures where rice has been a staple not just in diets but also in beauty rituals. The fermentation process enhances the nutritional profile of the rice, making it rich in amino acids, vitamins, and minerals that are beneficial for the skin. This traditional knowledge has been harnessed and refined over time, leading to the modern use of Hydrolyzed Aspergillus/Saccharomyces/Rice Ferment Lees Extract in cosmetic products.
To create this ingredient, rice is first fermented using Aspergillus and Saccharomyces. Aspergillus is a type of mold that breaks down the starches in rice into simpler sugars, while Saccharomyces, a type of yeast, further ferments these sugars. The result is a nutrient-rich lees, or sediment, which is then hydrolyzed to produce the final extract. This hydrolysis process breaks down the lees into smaller, more bioavailable molecules, making it easier for the skin to absorb and utilize the beneficial components.
