Science
Mechanism of Action
This extract functions through its rich profile of active compounds, including anthocyanins, flavonoids, and polyphenols. These phytochemicals exert significant anti-inflammatory actions by calming irritated tissues and visibly reducing skin redness and swelling. Concurrently, they deliver potent antioxidant protection, neutralizing damaging free radicals and bolstering the skin's natural defenses against environmental aggressors. Additionally, its astringent qualities help to visibly tighten pores and regulate sebum production, while its hydrating attributes contribute to improved skin softness and elasticity. The extract further supports skin health by promoting cell regeneration and exhibiting mild antibacterial effects against impurities.

Stability
The stability of its key active compounds, particularly anthocyanins, is sensitive to environmental factors including pH, chemical structure, and the presence of metal ions or copigments. Given its aqueous nature, microbial contamination is a consideration, requiring the inclusion of appropriate preservatives in formulations.

Safety
Safety Profile
Currently, the Cosmetic Ingredient Review (CIR) classifies data as insufficient, though it was placed on the 2023 CIR Priority List for review, with 196 reported uses in the 2022 FDA VCRP. It is broadly regarded as safe and well-tolerated across most skin types, including sensitive and delicate complexions, exhibiting a mild and soothing profile with minimal irritation risk. A preliminary patch test is advised for initial use.
