Science
Mechanism of Action
This ingredient operates via several distinct biological pathways within the skin. As an antioxidant, it actively neutralizes free radicals and safeguards cellular membranes from damage induced by reactive oxygen species. Its anti-inflammatory action involves the suppression of key pro-inflammatory mediators, such as nitric oxide and prostaglandin E2, alongside the downregulation of iNOS and COX-2 transcription factors, and modulation of NF-κB and MAPK signaling pathways. For skin brightening, it directly inhibits tyrosinase activity, which is crucial for melanin production. Anti-aging and anti-wrinkle effects are attributed to its antioxidant capacity and its ability to stimulate the expression of hyaluronic acid synthase genes (HAS-1, HAS-2, HAS-3), thereby enhancing endogenous hyaluronic acid levels for improved hydration and plumpness. Furthermore, components like the polysaccharide inulin act as skin conditioning and emollient agents, drawing and retaining moisture within the skin.
