Science
Mechanism of Action
This extract operates through several intricate biological pathways to significantly enhance skin quality and function. It provides a distinct firming effect by stimulating the synthesis of crucial structural proteins, specifically increasing both proteoglycan and collagen levels within the dermal matrix. For superior hydration, the extract optimizes the skin's natural ability to retain water and markedly decreases transepidermal water loss (TEWL), thereby fortifying the moisture barrier. Functioning as a powerful antioxidant, it actively neutralizes damaging free radicals and elevates the enzymatic activity of endogenous protectors like superoxide dismutase (SOD) and catalase. Furthermore, it exerts a notable soothing action by mitigating the activity of three distinct inflammation mediators. Its comprehensive anti-aging benefits are intrinsically linked to its protective action against free radical damage and its direct capacity to stimulate collagen production. Intriguingly, components such as shikimic acid within the extract contribute to cellular repair and strengthening by facilitating the differentiation of skin cells into skin-derived precursors (SKPs).
