Science
Mechanism of Action
This extract utilizes a triple-action bio-pathway: Carlina oxide provides targeted antimicrobial defense against Gram-positive bacteria; high concentrations of 3,5-dicaffeoylquinic acid esters inhibit inflammatory mediators to reduce erythema; and chlorogenic acids scavenge reactive oxygen species (ROS) to protect the skin barrier from premature aging.

Clinical Evidence
Medium confidence1%
Key findings
- 01 A 2024 study published in MDPI demonstrated that fractionated extracts rich in chlorogenic acids possess a Minimum Inhibitory Concentration (MIC) of 5.0 mg/mL against MRSA without exhibiting cytotoxicity to human fibroblasts.
- 02 Technical evaluations from plant milking platforms confirm that a 1% concentration significantly promotes skin conditioning and reduces inflammation via high-titer caffeoylquinic acid esters.
Transparency
Dusting Analysis
Due to its sophisticated manufacturing process and exotic botanical origin, this ingredient is frequently used at trace levels (below 0.1%) for marketing claims. To achieve measurable anti-inflammatory and purifying benefits, a minimum concentration of 1% is typically required.
The Formula
Formulation
Stability
The extract is heat-sensitive and must be incorporated during the cool-down phase of production at temperatures below 40°C to maintain biological activity.
Synergies
- Niacinamide
- Caffeine
- Hyaluronic Acid
Conflicts
- Strong oxidizing agents
- Heavy metal ions
Safety
Safety Profile
While not yet formally reviewed by the CIR, it has a documented history in traditional European medicine (Carlinae radix) and in vitro data confirms zero significant toxicity to human enterocytes and fibroblasts at therapeutic levels.
