Science

Mechanism of Action

Lactobacillus/Wasabia Japonica Root Ferment Extract functions through a multifaceted approach to optimize skin health. It serves as a potent antioxidant, effectively neutralizing free radicals and impeding oxidative DNA damage, mirroring the activity of Superoxide Dismutase (SOD). Its demonstrated antimicrobial and antibacterial properties help defend against various harmful microorganisms and inhibit odor-causing bacteria. The Lactobacillus component acts as a probiotic, fostering a balanced skin microflora, thereby contributing to barrier strengthening, moisturization, and soothing. Furthermore, naturally occurring isothiocyanates from Wasabia contribute anti-inflammatory effects by modulating key enzymatic pathways. This extract also supports moisture retention, promotes collagen stimulation, brightens skin tone, and helps correct visible signs of aging.
