Science
Mechanism of Action
This extract primarily functions through its robust antioxidant capacity, attributed to a rich profile of phenolic compounds such as protocateuic acid, gallic acid, and caffeic acid. These active components inhibit the formation of free radicals, scavenge existing ones, and chelate metal ions, thereby mitigating oxidative stress. Additionally, the extract demonstrates inherent antimicrobial properties, aiding in maintaining a balanced skin microbiome.

The Formula
Formulation
Stability
The extract is highly sensitive to heat; thermal processing can significantly reduce the levels of key phenolic compounds (e.g., gallic acid, protocateuic acid, caffeic acid by over 80-90%), thereby diminishing its biological activities, including antiradical, antibacterial, antifungal, antimutagenic, and antiproliferative properties. Cold or low-heat processing is recommended to preserve efficacy.
Safety
Safety Profile
While the Ornithogalum umbellatum plant contains cardiac glycosides and is considered unsafe for medicinal ingestion due to potential toxicity, this concern pertains to oral consumption, not topical application. For cosmetic topical use, the ingredient is rated as 'Irritant Free' by SkinSAFE, suggesting a low irritancy potential within formulated products. However, individuals with extreme sensitivity might experience dermatitis from direct contact with the raw bulb.
