Aspergillus Ferment
Explained
Aspergillus Ferment is created when Aspergillus fungi is fermented under controlled conditions. This is the same fungi used to make sake, miso, and soy sauce.
The fungi breaks down to produce a mix of enzymes, amino acids, vitamins, and bioactive compounds during fermentation.
One such compound is kojic acid; kojic acid is widely considered a gentler alternative to hydroquinone. You should know: the amount of kojic acid in Aspergillus Ferment will vary depending on species used and how the fermentation was done.
There's an in-vitro study from 2019 found that ceramide-like compounds from Aspergillus luchuensis helped skin cells turn on the genes related to barrier repair and moisture retention. Just keep in mind this was tested on cells in a lab and not on actual people's faces.
Fungal acne
If you're someone who deals with fungal acne (malassezia folliculitis), you might want to instinctively want to skip this ingredient.
That's understandable since it is derived from a fungus. It's worth knowing that Aspergillus and Malassezia are completely different organisms and there's no research suggesting that Aspergillus Ferment feeds or worsens malassezia overgrowth on the skin.
However, if you're actively managing fungal acne, being cautious with any new ingredient is reasonable.
