Science

This ingredient is a complex blend, with each fermented component contributing synergistically to skin health. Lactobacillus ferment supports the skin's surface harmony, aids in rebuilding the protective barrier, and calms inflammation while safeguarding against detrimental bacteria. It helps regulate hydration, rebalance the skin microbiome, and refines texture and clarity through congestion reduction and oil regulation. Additionally, it functions as a DNA repair enzyme, exhibits anti-microbial and anti-inflammatory properties beneficial for conditions like acne and rosacea, and can inhibit tyrosinase to brighten skin and diminish hyperpigmentation by producing antioxidants such as ferulic acid and polyphenols. Fermented hydrolyzed soy protein enhances the bioavailability of isoflavones, providing potent antioxidant and immunomodulatory benefits, stimulating collagen production for improved firmness and elasticity, and effectively binding moisture. Catharanthus roseus seed extract (periwinkle) is instrumental in inhibiting and preventing skin aging processes, offering protection and nourishment against free radical damage. Its antioxidant, antibacterial, and antifungal properties may assist in managing acne and skin infections by reducing redness and swelling. Lastly, yeast extract stimulates cell regeneration and collagen synthesis, leading to improved skin elasticity. It delivers significant moisturizing effects, visibly reducing fine lines and wrinkles, and imparts anti-inflammatory and soothing benefits for irritated skin, while fortifying the skin's immune system and enhancing moisture retention through its richness in natural moisturizing factors (NMFs).
