Science
Mechanism of Action
The extract's efficacy primarily stems from the *Chrysanthemum indicum* component, rich in flavonoids like linarin and luteolin. It functions as a potent antioxidant, actively scavenging reactive oxygen species (ROS) and providing defense against damage induced by UV radiation, pollution, and the aging process. Its anti-inflammatory action is demonstrated by inhibiting UV-induced inflammation, reducing inflammatory cytokine production, and decreasing NF-κB, ERK, and p38 MAPK activation. Skin-whitening and anti-melanogenic effects are achieved through the inhibition of tyrosinase activity, leading to a reduction in melanin levels. Additionally, it exhibits antimicrobial properties against various common skin bacteria. The *Erigeron annuus* component contributes complementary anti-fungal, anti-inflammatory, and antioxidant activities, attributed to its diverse profile of coumarins, flavonoids, and terpenoids, collectively protecting, calming, and evening the skin tone.

The Formula
Formulation
Stability
The *Chrysanthemum indicum* component is water miscible, and its extracts are typically prepared with water or ethanol, indicating good solubility in polar solvents. To maintain optimal antioxidant activity, controlled extraction temperatures (e.g., 40°C during evaporation) are recommended.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not specifically assessed the combined CHRYSANTHEMUM INDICUM/ERIGERON ANNUUS EXTRACT. However, safety data for *Chrysanthemum indicum* indicates a low risk of toxicity and mutagenicity, with no mortality or clinical signs observed in acute oral toxicity studies up to 2,000 mg/kg body weight/day, and no mutagenicity in bacterial reverse mutation tests up to 500 μg/mL. Its widespread use in traditional medicine and as a food/tea suggests a history of safe topical application.
