What Is Bacillus/Colocasia Esculenta Root Extract/Glycerin Ferment Filtrate?
Bacillus/Colocasia Esculenta Root Extract/Glycerin Ferment Filtrate is a skin care ingredient made by fermenting taro root extract with a friendly Bacillus bacteria in a base of plant derived glycerin. Taro, known scientifically as Colocasia esculenta, is a starchy root rich in natural sugars, minerals and skin loving amino acids. During fermentation the bacteria break down large plant molecules into smaller ones that are easier for skin to use and add their own peptides and enzymes to the mix. Once the process is complete the mixture is filtered, leaving a clear liquid packed with moisture binding sugars, soothing amino acids and a light protective film of bacterial by products.
The concept of using fermented plant extracts in beauty started in East Asia where gentle fermentation was praised for boosting the potency of herbal ingredients. As the trend spread globally formulators began pairing taro root with Bacillus because the root is naturally softening while the bacteria are reliable ferment workers. Today this ferment filtrate shows up in hydrating sheet masks, daily moisturizers, barrier repair creams, calming after sun gels and many anti aging serums that aim to smooth and protect the skin surface.
