What Is Aspergillus/Defatted Rice Bran/Alcohol/Borneol Ferment Filtrate?
Aspergillus/Defatted Rice Bran/Alcohol/Borneol Ferment Filtrate is a skin care ingredient made by letting the friendly mold Aspergillus ferment defatted rice bran together with a small amount of alcohol and natural borneol. When the fermentation is finished the mix is filtered, leaving a clear liquid rich in skin loving compounds such as amino acids, simple sugars, vitamins and soothing plant molecules that come from the rice bran and borneol.
Rice bran has a long history in beauty rituals across Asia where leftover rice water was used to keep skin smooth. Modern labs took that idea further by removing the heavy oils from rice bran then using Aspergillus to break the material down into smaller pieces, making it easier for skin to enjoy the good stuff. Borneol, an aromatic extract from certain trees, is added to boost the calming scent and possible soothing effect, while alcohol keeps the mix clean during the controlled fermentation.
The filtrate finds its way into many personal care formulas. You can spot it in lightweight essences, hydrating toners, sheet masks, serums that target dullness, all in one moisturizers and anti-aging creams that promise smoother texture and a healthy glow.

Comedogenic Rating
Rating: 0-1 out of 5
The filtrate is made from defatted rice bran, which means virtually all pore-clogging oils are removed. After fermentation and filtration the result is a watery solution rich in small molecules like amino acids and sugars, with no heavy waxes or butters that typically trigger breakouts. A trace of alcohol is present but it quickly evaporates and does not contribute to clogged pores. Because of this light, oil-free profile the ingredient earns a non-comedogenic score at the very lowest end of the scale.
Suitable for acne-prone and breakout-prone skin.
Only highly occlusive or greasy companion ingredients in the finished formula would raise pore-clogging risk, not the ferment itself.
Summary
Aspergillus/Defatted Rice Bran/Alcohol/Borneol Ferment Filtrate acts mainly as a skin conditioner, supplying moisture-binding sugars, softening amino acids and antioxidant compounds created during fermentation. These light nutrients smooth texture, improve suppleness and support an even, healthy-looking glow without adding weight or oil.
While not the most famous ferment in the beauty aisle, it appears in a growing number of Asian-inspired essences, toners and masks where consumers look for gentle plant-based boosters that leave skin fresh and dewy.
Overall safety data are positive with very few reports of irritation. As with any new cosmetic ingredient, it is smart to perform a small patch test when trying a product that features the filtrate to ensure personal compatibility.
