Science
Mechanism of Action
It utilizes a three-pronged approach to skin health: disrupting the cell membranes of pathogenic bacteria to maintain a healthy microbiome, inhibiting COX enzymes to stop the synthesis of pro-inflammatory prostaglandins, and neutralising oxidative stress through direct free-radical scavenging and prevention of lipid peroxidation.

Key findings
- 01 Demonstrated Minimum Inhibitory Concentration (MIC) of 1.25 mg/mL against pathogenic strains including P. aeruginosa.
- 02 Achieved significant DPPH radical scavenging (antioxidant) activity with an IC50 of 81.69 µg/mL.
- 03 Shown to be highly effective at 20% concentrations in complex aqueous formulations for microbial control.
Transparency
Dusting Analysis
Because it often serves a dual purpose as a 'fragrance' or 'botonical' on labels, brands frequently use it at negligible levels (below 0.1%) for marketing claims without providing the antimicrobial or antioxidant benefits seen in clinical data.
The Formula
Formulation
Stability
Highly stable in neutral to slightly alkaline environments; however, the active iridoid glycosides are heat-sensitive and may degrade if exposed to high temperatures or highly acidic conditions.
Synergies
- Niacinamide
- Hyaluronic Acid
- Chelating agents
Conflicts
- Strong oxidizing agents
- Low pH Ascorbic Acid formulations
