Science
Mechanism of Action
This extract's efficacy is rooted in its rich phytochemical profile, including polyphenols, flavonoids (such as gallic acid, ellagic acid, myricitrin), and carotenoids. These compounds neutralize reactive oxygen and nitrogen species, effectively combating oxidative stress. Its anti-inflammatory and broad-spectrum antimicrobial (antibacterial and antifungal) actions are further supported by these phenolic compounds and flavonoids. Additionally, it provides an astringent effect, aiding in skin tightening, and functions as a conditioning agent to maintain skin feel and appearance.

The Formula
Formulation
Stability
The extract exhibits hydrophilic characteristics, ensuring adequate water solubility in formulations. The fruit itself has a naturally low pH, typically ranging from 3.13 to 3.55, suggesting compatibility with slightly acidic topical applications. Optimal stability and efficacy can be influenced by specific extraction methods, solvent choices, and storage conditions.
Safety
Safety Profile
Eugenia Uniflora extracts have demonstrated low toxicity in in vitro studies and non-toxic, non-genotoxic action in vivo with aqueous leaf extracts, indicating a favorable safety margin for topical use. Reputable databases like EWG Skin Deep rate common concerns (e.g., allergies, developmental toxicity) as 'LOW', and INCI Beauty reports 'No penalty' across categories. Formal cosmetic safety reviews (CIR, SCCS, FDA) with defined usage restrictions or maximum concentrations are not yet available.
