Science
Mechanism of Action
The mechanism of action for Fagus Crenata Bark is primarily inferred from in vitro research on Fagus genus extracts, notably Fagus sylvatica bark and bud extracts. These extracts are rich in phenolic compounds, such as vanillic acid, gallic acid, and epicatechin, which contribute to observed antioxidant, antibacterial, antifungal, and anti-tyrosinase activities. Specifically, Fagus sylvatica bud extracts have demonstrated the ability to stimulate natural collagen and elastin synthesis, enhance skin hydration by boosting Natural Moisturizing Factor (NMF) components, increase cellular oxygen consumption, and promote healthy skin cell turnover. These collective properties suggest Fagus Crenata Bark contributes to revitalized skin appearance and protection.
