What it is
Aspergillus Ferment is the product of fermenting a substrate with Aspergillus, a genus of fungi widely used in traditional food fermentation such as koji. In cosmetics the resulting ferment is used as a skin-conditioning ingredient and is often marketed for its connection to fermentation-derived skincare. In sunscreens it appears as a supporting conditioning additive rather than a UV filter.
Safety & warnings
Ferment ingredients are generally well tolerated, though those with known sensitivities to mold- or fungus-derived materials should be cautious and may patch test. It is not a recognized fragrance allergen, and it is not associated with notable comedogenicity.
Origin & sourcing
Natural-derived via biotechnology; produced by fermentation using Aspergillus microorganisms, then filtered and processed for cosmetic use.
