Science

Mechanism of Action

Mentha Spicata Leaf Extract works by neutralizing free radicals, thereby safeguarding vital skin proteins from oxidative damage. Its anti-inflammatory action helps calm irritated skin, partially achieved through the inhibition of prostaglandin synthesis. The extract also provides antimicrobial benefits against common body odor-causing and acne-causing bacteria, alongside an astringent effect that can visibly refine pore size. Furthermore, it enhances skin hydration, fortifies the skin barrier, and supports elasticity, offering protection against environmental stressors.

While generally recognized as safe (GRAS) by the FDA for food use, the EWG Skin Deep® database rates Mentha Spicata Leaf Extract with 'HIGH' concern for allergies and immunotoxicity, identifying it as a 'Known human toxicant or allergen' by the EU Cosmetics Directive. Allergic reactions, though generally rare, have been reported. Regulatory guidance for related Mentha Piperita suggests a maximum of 5% in formulations due to potential irritation from menthol content, a consideration relevant for Mentha Spicata as well. High oral doses may lead to gastrointestinal upset.
