Science

This ferment acts through multifaceted biological pathways. It proactively supports the extracellular matrix by protecting existing collagen and elastin, thereby maintaining structural integrity and visibly reducing wrinkles. It delivers significant hydration, brightens skin tone by inhibiting tyrosinase, and exhibits potent antioxidant and anti-inflammatory effects. Furthermore, it stimulates autophagy in senescent keratinocytes, reinforces the skin barrier, aids in DNA repair from environmental stressors, helps maintain optimal skin pH, and possesses antibacterial properties.
