Science
Mechanism of Action
This extract functions via several biological pathways: it acts as a potent antioxidant and anti-inflammatory agent, reducing cellular damage and soothing irritation. For anti-aging, it boosts type I collagen mRNA expression and inhibits enzymes like elastase and MMP-1 that degrade skin structure. Its antibacterial activity targets common skin pathogens such as Propionibacterium acnes, Staphylococcus aureus, and Pityrosporum ovale. In the context of hair growth, it increases Stem Cell Factor (SCF) and hair growth-promoting cytokines (IGF-1, KGF), while suppressing mast cell proliferation and reducing TGF-β1 expression. Additionally, it provides astringent and emollient benefits.
