Science
Mechanism of Action
This extract fortifies the skin's protective barrier and serves as an antioxidant, neutralizing free radicals that contribute to premature aging. It stimulates microcirculation, enhancing oxygen supply to skin cells, and delivers a notable refreshing sensation. Its antibacterial, antimicrobial, and anti-fungal actions contribute to clearer skin, while its anti-inflammatory effects are mediated by inhibiting pro-inflammatory cytokines like TNF-α and IL-6. It also helps regulate sebum production, minimizing pore clogging, and provides an astringent effect for tightened pores. In wound healing, it significantly reduces the inflammatory phase, modulates inflammatory cell presence, boosts macrophage activity, and promotes angiogenesis and epithelialization, alongside an increase in TGF-β gene expression.

Key findings
- 01 Topical application of Mentha piperita essence demonstrated accelerated cutaneous wound healing, reducing the inflammatory period, decreasing inflammatory cells, increasing macrophages, and enhancing angiogenesis, resulting in a 99.73% wound healing rate in one experimental group after 14 days. The concentration used in this study was unspecified.

Dusting Analysis
Mentha Piperita Herb Extract is effective at various concentrations. While regulatory guidelines for formulations suggest use typically up to 5%, a specific internal component, pulegone, has a maximum concentration limit of 1% to ensure safety. This indicates effective concentrations are generally achievable within these safe limits, minimizing the risk of 'dusting' by formulators.
The Formula
Formulation
Conflicts
- It can enhance the dermal penetration of other active ingredients, necessitating careful formulation to prevent unintended effects or increased absorption of other components.
- High concentrations or use on sensitive skin can lead to irritation due to its menthol content.
Safety
Safety Profile
The CIR Expert Panel deems Mentha Piperita Extract safe for cosmetic use, provided the concentration of pulegone, a natural constituent, does not exceed 1%. It is also generally recognized as safe (GRAS) by the US FDA for food. Formulators should be aware that it can increase the penetration of other ingredients, potentially impacting their safety profiles. While generally safe, its high menthol content carries a moderate risk of irritation for sensitive individuals or at elevated concentrations, therefore patch testing is recommended for sensitive skin. Regulatory guidelines typically advise usage within limits, often up to 5% in formulations.
