What Is Aspergillus/Rice Ferment Extract?
Aspergillus/Rice Ferment Extract is a liquid derived from plain rice that has been fermented with the help of Aspergillus, a safe mold used in food and beverage production for centuries. During fermentation the microorganisms break down rice starches into smaller molecules like amino acids, peptides and sugars that skin can readily absorb. These small molecules give the extract its softening and water-binding qualities.
The idea of using fermented rice for beauty is rooted in traditional Japanese sake brewing where workers were known for having smooth youthful hands. Modern cosmetic chemists took note of this observation and refined the process to create a stable extract suitable for creams and lotions.
To make it, polished rice is cooked, inoculated with Aspergillus spores then kept in a warm humid setting so the mold can grow and start fermentation. After a set time the mixture is filtered and purified, leaving behind a clear to pale yellow liquid rich in skin-loving nutrients.
You will often spot Aspergillus/Rice Ferment Extract in hydrating toners, sheet masks, daily moisturizers, anti-aging serums and brightening essences where it works alongside other soothing ingredients.

Who Can Use Aspergillus/Rice Ferment Extract

Its humectant nature helps dry skin hold water while its quick absorption means it will not weigh down oilier complexions. Sensitive skin usually tolerates it well thanks to its gentle nutrient profile though anyone with a known allergy to rice or mold derived ingredients should proceed with caution.
The extract is produced by fermenting rice with a microorganism rather than using any animal materials so it is considered vegan and vegetarian friendly.

Comedogenic Rating
Rating: 0/5
Aspergillus/Rice Ferment Extract is a water based fluid with no heavy oils or waxes so it does not clog pores and is classed as non comedogenic. The molecules it contains are mainly amino acids, peptides and simple sugars that dissolve easily in water and rinse away without leaving an occlusive film. This makes the extract suitable for acne prone or congestion prone skin types. Because the ingredient itself is not oily it is rarely the cause of breakouts, though impurities in a final formula or poor preservation could still trigger issues.
Summary
Aspergillus/Rice Ferment Extract acts as a humectant and skin conditioning agent by delivering small water attracting molecules that pull moisture into the outer layers of skin and feed the barrier with amino acids for a smoother softer feel. Its feather light texture means it layers well with other hydrators making it a popular pick in Asian beauty toners, essences and sheet masks though it remains less common in Western lines.
Overall safety is high with low irritation potential and no known hormone or sun sensitivity concerns. As with any new cosmetic ingredient it is wise to perform a quick patch test when trying a product that contains it especially if you have very reactive skin.
