Science
Mechanism of Action
This ferment filtrate actively neutralizes free radicals, providing robust antioxidant defense against environmental stressors and contributing to anti-aging pathways. It promotes cellular regeneration, aiding the skin's natural recovery from damage and potentially refining skin texture and reducing scar appearance. Furthermore, it calms irritation, reduces redness, and strengthens the skin barrier through its inherent anti-inflammatory and moisturizing capabilities. Its brightening action is attributed to inhibiting melanin production and tyrosinase activity, which collectively contribute to a more even and luminous skin tone.
