In lab tests on skin cells, Galactomyces ferment filtrate activated protective pathways that boosted the skin's natural moisture barrier, reduced inflammation markers linked to aging, and increased antioxidant defenses against UV and environmental stress. The ingredient specifically ramped up filaggrin (a natural moisturizer your skin makes) and dialed down inflammatory signals associated with skin aging.

Researchers tested Galactomyces ferment filtrate on human skin cells in a controlled lab environment, measuring how it affected specific genes and proteins involved in moisture, inflammation, and skin aging.
