Science & Benefits

Japanese Knotweed is the primary botanical source of high-purity Resveratrol. This polyphenol is a potent antioxidant that protects the skin's internal hydration levels by neutralizing the free radicals that degrade hyaluronic acid and collagen. As a humectant, it provides a soothing, water-based moisture. It is zero-comedogenic and zero-irritant. For acne-prone individuals, it acts as a 'biological shield,' preventing environmental stressors from triggering the inflammatory cascade that leads to both breakouts and premature aging.
