Science
Mechanism of Action
This extract, rich in active constituents such as breviscapine and scutellarin, operates via several mechanisms. It effectively reduces inflammation by modulating key pro-inflammatory mediators including IL-1β, IL-6, MMP13, and NOS2. Simultaneously, it inhibits melanin formation and accelerates melanin metabolism, contributing to a brighter and more uniform complexion. Scutellarin has specifically demonstrated inhibition of TOPK activity and phosphorylation of ERK1/2 and histone H3 in melanoma cells, indicating its role in pigment regulation. Furthermore, its antioxidant properties combat oxidative stress, while its ability to increase skin moisture content addresses dryness.

Formulation
Stability
Breviscapine injection shows stability in color, pH, and drug content around pH 6.8. While water solubility of components is noted at pH 8–8.5 for extraction, key active components like scutellarin are generally poorly water-soluble, preferring hot water, ethanol, or dilute alkali solutions. Formulators may need to consider advanced techniques, such as liposome preparation, to optimize its solubility and utilization.
Safety
Safety Profile
Erigeron breviscapus is referenced as a safe medicinal material with acute and subacute toxicity studies supporting its internal use. However, a specific cosmetic safety assessment by the CIR or SCCS is currently unavailable. A derivative, Lifeflower® Breviscapine (containing at least 90% scutellarin), holds self-affirmed GRAS status for food, beverages, and dietary supplements, but this designation does not directly extend to topical cosmetic applications.
