PEDIOCOCCUS/PANAX GINSENG ADVENTITIOUS ROOT EXTRACT FERMENT EXTRACT.

Fermentation, particularly by Pediococcus, facilitates the bioconversion of ginsenosides into more readily absorbed metabolites, such as Compound K (CK), thereby amplifying their efficacy. This extract is believed to augment the skin's moisture content and reduce transepidermal water loss (TEWL) through its polysaccharide components, thus reinforcing the protective skin barrier. It demonstrates potent antioxidant capabilities, shielding the epidermis from environmental stressors like UV radiation and pollution by inhibiting matrix metalloproteinases-1 (MMP-1), enzymes implicated in collagen degradation. Furthermore, fermented ginseng promotes collagen synthesis by activating transforming growth factor-β (TGF-β) and stimulating fibroblasts. It supports improved skin elasticity, microcirculation, and cellular oxygenation, which collectively boost collagen production. The ingredient may also mitigate hyperpigmentation by reducing melanin content through tyrosinase activity inhibition. Additionally, it supports a balanced skin microbiome and healthy cell regeneration, with Pediococcus pentosaceus strains exhibiting antimicrobial activity against pathogenic bacteria and promoting host cell adhesion.
