Science

Mechanism of Action

Operating at a cellular level, this ingredient significantly boosts hyaluronic acid (HA) levels and enhances the expression of hyaluronan synthase 2 and aquaporin 3 (AQP3) in skin cells, optimizing hydration. It reinforces skin barrier integrity by increasing tight junction proteins such as claudins and occludin, alongside upregulating filaggrin (FLG) and involucrin (IVL). The ferment stimulates collagen production, providing elasticity and reducing signs of aging. Its fermented peptides exhibit notable antioxidant properties, with a free radical scavenging rate of up to 45%, and potent anti-inflammatory effects. Furthermore, it promotes fibroblast proliferation, reduces reactive oxygen species, activates natural moisturizing factors (NMFs) and ceramides, and demonstrates an inhibitory effect on melanin synthesis, contributing to a more even skin tone. It also harmonizes the skin's microflora, soothing stressed skin.
