Science
Mechanism of Action
This extract imparts a distinct cooling sensation by activating cold-sensitive receptors via its menthol and menthone content. Its anti-inflammatory action is mediated through pathways like the inhibition of ERK/NF-κB signaling and modulation of the NLRP3 inflammasome, effectively reducing irritation and redness. Bioactive flavonoids contribute to its antioxidant capacity, shielding the skin from free radical damage. Furthermore, it exhibits antibacterial properties, aiding in the regulation of sebum and combating acne-causing bacteria, making it particularly beneficial for oily skin types.

Stability
No specific optimal pH range for the stability of the extract in cosmetic formulations was identified in the available research. The plant itself thrives in soil pH between 6.5 and 8.
Safety
Safety Profile
Generally considered safe for most users, particularly when formulated at low concentrations. However, individuals with sensitivities to the mint family of plants may experience allergic reactions, manifesting as irritation, itching, or redness. A preliminary sensitivity test is strongly recommended prior to widespread use, especially for those with a history of sensitive or reactive skin. European Cosmetics Regulation outlines general usage guidelines, though no specific maximum concentration for this extract was determined from the provided sources.
