Science
Mechanism of Action
Cirsium flower/leaf/stem extract operates through multiple pathways to enhance skin health. Its primary actions include robust antioxidant effects, attributed to phenolic compounds like silychristin, taxifolin, chlorogenic acid, linarin, and pectolinarin, which actively neutralize oxidative stress. It also exhibits anti-inflammatory properties, observed in its ability to mitigate inflammatory responses, and possesses antimicrobial capabilities against various bacteria and fungi, often due to its flavonoid content. Furthermore, the extract promotes anti-aging benefits by improving skin elasticity and reducing wrinkle depth, collectively functioning as a broad-spectrum skin conditioning agent.

Key findings
- 01 A 10 mg/L methanol extract from *Cirsium japonicum* flowers, leaves, and stems effectively mitigated juglone-induced oxidative stress in *Caenorhabditis elegans*. It is important to note that higher concentrations, such as 100 mg/L, in this model did not yield significant antioxidative activity and suggested potential toxic effects.
- 02 Unspecified concentrations of *Cirsium japonicum* flower extract have been observed to enhance skin elasticity and reduce the appearance of wrinkles, indicating its potential as an active anti-aging component.
- 03 When incorporated into thermosensitive nanofibers, *Cirsium setosum* extract at an unspecified concentration demonstrated significant wound healing capabilities, achieving over 95% healing within 14 days by reducing inflammation, promoting re-epithelialization, and supporting collagen deposition.

The Formula
Formulation
Stability
Extraction methods employing diverse solvents such as water, methanol, ethanol, diethyl ether, and hexane indicate the presence of both water-soluble and oil-soluble components, suggesting broad solubility. Formulators should exercise caution regarding concentration, as high levels (e.g., 100 mg/L of crude *Cirsium japonicum* extracts in a *C. elegans* model) have shown potential adverse effects.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not specifically evaluated 'Cirsium Flower/Leaf/Stem Extract', indicating a lack of formal safety assessment for cosmetic applications. While studies in *Caenorhabditis elegans* suggest potential adverse effects at concentrations around 100 mg/L, this data is not directly transferable to human topical safety. General reports from INCIDecoder indicate low irritancy and comedogenicity; however, further specific safety data for human dermal use is needed.
