ASPERGILLUS/CASTANEA CRENATA PELLICLE FERMENT EXTRACT

Fermented Chestnut Extract

Safety grade: A

This ingredient is made by fermenting the outer layer of chestnuts using a beneficial fungus called Aspergillus. Fermentation breaks down the chestnut material into smaller, more easily absorbed compounds that are beneficial for hair and skin.

It conditions and softens both hair and skin by providing moisture and nutrients that improve texture and appearance.
