What it is
Fermented soybean extract using Pediococcus species; fermentation converts isoflavone glycosides (genistin, daidzin) to bioactive aglycones (genistein, daidzein) with significantly enhanced skin penetration and bioavailability; genistein exerts estrogen-like effects that stimulate collagen and hyaluronic acid synthesis in dermal fibroblasts; postbiotic fraction adds barrier-protective and anti-inflammatory properties; used in anti-aging, skin-firming and sensitive-skin formulations.
