Science
Mechanism of Action
This extract functions primarily through its high concentration of polyphenols, flavonoids, and anthocyanins, which exert potent antioxidant and anti-inflammatory effects. It actively neutralizes oxidative and nitrative stressors, such as peroxynitrite, safeguarding vital skin proteins and lipids from damage. Furthermore, its phenolic compounds absorb UV radiation (200-400 nm), contributing to photoprotection, while also providing skin conditioning and reducing visible redness, and may also exhibit tyrosinase inhibitory activity.

Stability
As a polyphenol-rich extract, its stability is likely pH-dependent; however, specific optimal pH ranges for the overall extract are not currently defined. It is typically extracted using hydroalcoholic solvents, and its anthocyanin components are water-soluble.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not reviewed this ingredient. While in vitro tests on human peripheral blood mononuclear cells suggest a safe profile, a study on human liver cancer cells (Hep G2) indicated significant inhibitory effects on proliferation and prooxidant behavior at concentrations exceeding 50 µg/mL, leading to necrotic and apoptotic cell death. Dermal toxicity remains undetermined.
