Ingredients Details
Galactomyces Ferment Filtrate
Common Name(s): Galactomyces ferment filtrate,sake yeast postbiotic,multi-function brightening active
CAS Number: N/a
DESCRIPTION
What It Does: Brightens skin tone by inhibiting melanin transfer from melanocytes to keratinocytes (not tyrosinase inhibition), strengthens the skin barrier by upregulating involucrin and filaggrin expression, minimises pore appearance, and provides antioxidant protection from the ferment's organic acid and flavonoid complex.
Why It's Used: Gff's brightening mechanism differs from all tyrosinase inhibitors โ it blocks melanosome transfer rather than melanin synthesis, providing additive brightening when combined with tyrosinase inhibitors and targeting the previously unaddressed transfer step.
How It Works: Gff contains niacinamide (inhibits melanosome par-2 transfer), arbutin-related compounds (tyrosinase inhibition), vitamin b complex, alpha-arbutin, and organic acids. the combined transfer inhibition + tyrosinase inhibition + antioxidant activity explains multi-step brightening. barrier upregulation occurs through fatty acid ceramide precursor provision.
