Antioxidant Anti-inflammatory Moisturizing Hydrating Enhances Skin Elasticity Supports Collagen Synthesis Anti-aging Skin Brightening Reduces Hyperpigmentation Soothing Sebum Regulation

Science

Mechanism of Action

The efficacy of Pueraria Thunbergiana Root Extract is rooted in its potent isoflavone content, which confers significant antioxidant and anti-inflammatory effects on the skin. It supports skin vitality by boosting moisturization and stimulating collagen synthesis, leading to improved skin elasticity and a reduction in the appearance of fine lines and wrinkles. The extract promotes skin brightening through its inhibitory action on melanogenesis in vitro, specifically by downregulating microphthalmia-associated transcription factor (MITF) via Akt/GSK-3β activation, which decreases the transcription of tyrosinase and tyrosinase-related protein 1. Additionally, it interrupts tyrosinase maturation by inhibiting α-glucosidase. Its anti-inflammatory capabilities help to calm and soothe irritated skin, and it may also play a role in balancing sebum production.
