Science
Mechanism of Action
The extract functions via a dual-action pathway: it neutralizes oxidative stress by scavenging superoxide anion radicals through enzymatic activity (SOD and CAT mimicry) and disrupts microbial cell membranes using its natural monoterpene profile—specifically carvone, pulegone, and trans-caryophyllene. Additionally, it enhances the skin's barrier by improving moisture retention and suppressing inflammatory markers that cause surface redness.

Key findings
- 01 Nostro, A., et al. (2010) demonstrated that at 1.0-2.0%, the extract provides effective antimicrobial activity satisfying European Pharmacopoeia standards.
- 02 Moattar, F. S., et al. (2018) confirmed significant antioxidant enzymatic power, specifically in protecting against superoxide anion-induced oxidative stress.

Dusting Analysis
This ingredient is frequently used at 'label claim' levels (below 0.1%) to market a botanical profile. However, clinical data suggests that concentrations of at least 1.0% are required to achieve its documented antimicrobial and significant antioxidant benefits.
The Formula
Formulation
Stability
Highly prone to photo-oxidation and degradation. It requires stabilization with chelating agents or antioxidants like citric acid and must be stored in light-protected packaging.
Synergies
- Vitamin E
- Chelating agents (EDTA, Sodium Phytate)
- Glycerin
Conflicts
- Strong oxidizing agents
- Highly alkaline environments (pH > 8.0)
Safety
Safety Profile
While generally safe, the extract contains pulegone, which is subject to specific concentration limits in some regions if used as a fragrance component.
