About
A fermented ingredient from the Aspergillus mold — fermentation breaks down the substrate into smaller, more bioavailable compounds that skin can absorb more easily.
Aspergillus ferment refers to the product of fermenting various substrates (often plant material or sugars) using Aspergillus species — most commonly A. niger, A. oryzae or A. sojae. Fermentation produces bioactive peptides, organic acids, enzymes and polyamines that can have skin-beneficial effects. The restriction note about ozone-depleting substances likely refers to certain historical manufacturing processes involving CFCs, not the ingredient itself. Safety depends heavily on the fermentation substrate and downstream processing. Aspergillus niger-derived ingredients have a long history in food (citric acid) and cosmetics.
