Science

Mechanism of Action

Operating through a complex array of phytochemicals including phenols, flavonoids (such as quercetin and rutin), tannins, and triterpenoids (like betulin, lupeol, and taraxerol), Rhododendron arboreum Bark Extract delivers multifaceted benefits. Its potent antioxidant activity effectively neutralizes free radicals, mitigating oxidative stress. Concurrently, its anti-inflammatory properties, largely attributed to flavonoids and tannins, help to calm and reduce skin redness. Furthermore, the extract exhibits antimicrobial and antifungal effects, contributing to a healthier, more balanced skin environment, while also functioning as an effective skin conditioner.
