Science
Mechanism of Action
Mentha Piperita Leaf Cell Extract operates by reinforcing the skin's natural protective barrier and providing potent antioxidant defense against free radicals, thereby mitigating oxidative stress. Its inherent menthol content delivers a refreshing and cooling sensation. The extract exhibits soothing, anti-inflammatory, and antimicrobial properties. It aids in balancing sebum production, reducing pore congestion, and offering an astringent effect for refined pores. Furthermore, it contributes to skin hydration, facilitates wound healing by shortening inflammation and promoting angiogenesis and epithelialization. It may also suppress ATP release from keratinocytes, potentially minimizing dermal thinning and wrinkle formation.

Stability
The bioactive compounds in Mentha Piperita Leaf Extracts are chemically unstable and prone to degradation from oxygen, light, and high processing temperatures. Encapsulation is a recommended strategy to enhance stability. Optimal formulation pH for this extract is observed within the range of 5.9 to 6.2.
Safety
Safety Profile
The CIR Expert Panel deems Mentha Piperita Leaf Extract safe for cosmetic use, provided the pulegone concentration does not exceed 1%. Regulatory guidelines typically recommend use up to 5% in formulations. Due to its menthol content, higher concentrations or use on sensitive skin can induce irritation, necessitating patch testing. Formulators should also note that menthol can enhance the penetration of other ingredients, which is a crucial consideration for overall product safety.
