Science
Mechanism of Action
This extract delivers deep hydration through its inherent humectant properties and the presence of L-lactic acid, a component of the skin's Natural Moisturizing Factor. It effectively calms and refreshes irritated skin, offering cooling effects and contributing anti-inflammatory action via compounds like shikimate dehydrigenase. Abundant antioxidants, including vitamins A, B1, B2, C, and E, shield the skin from oxidative damage. Furthermore, specific cucurbitacins (D and 23,24-dihydrocucurbitacin D) inhibit tyrosinase and melanin synthesis, aiding in skin brightening. Its anti-hyaluronidase and anti-elastase activities help preserve skin elasticity and hyaluronic acid levels, supporting anti-aging efforts, while flavonoids contribute to wound healing and anti-itching effects. A mild astringent property also assists in managing excess sebum.
