MENTHA SUAVEOLENS LEAF EXTRACT.

Valuable / ASTRINGENT, SKIN CONDITIONING

Mentha Suaveolens Leaf Extract, derived from apple mint, is a multifaceted botanical ingredient celebrated for its potent antioxidant and anti-inflammatory properties. It actively shields skin cells from oxidative stress and environmental damage, while also demonstrating significant anti-aging benefits, particularly against thermal-induced aging.

Summary

Antioxidant Anti-inflammatory Soothing Skin-Conditioning Astringent Oil Regulating Cytoprotective Anti-aging Tyrosinase Inhibitor

Science

Mechanism of Action

This extract functions primarily as a robust antioxidant, actively neutralizing free radicals and offering comprehensive cytoprotection against oxidative damage. Its anti-inflammatory capabilities mitigate skin irritation and redness, while its astringent properties contribute to a refined, tightened skin appearance and balanced oil secretion. Furthermore, it directly combats thermal skin aging by suppressing the production of reactive oxygen species (ROS), matrix metalloproteinases (MMPs), and interleukin-8 (IL-8), and modulating mitogen-activated protein kinases (MAPKs), enhancing cellular resilience via Nrf2 activation.

Key findings

  1. 01 In murine RAW 264.7 macrophages, concentrations from 25-400 µg/mL (in vitro) demonstrated significant cytoprotective and anti-inflammatory activities.
  2. 02 At an in vitro concentration of 1 mg/mL, tyrosinase inhibition rates ranged from 11.35% to 39.65%, indicating potential skin brightening effects.
  3. 03 An aqueous extract effectively inhibited ROS, MMPs, and IL-8 production, and suppressed MAPKs in human dermal fibroblasts (HDFs) exposed to heat shock, indicating anti-thermal skin aging activity.
  4. 04 In human keratinocyte HaCaT cells, an aqueous extract provided cytoprotection against hydrogen peroxide-induced oxidative stress and apoptosis, linked to Nrf2 activation.

Stability

The extract exhibits optimal stability within a slightly acidic to neutral pH range of 5.0 to 6.0, closely reflecting the plant's natural pH. Given that general mint extracts can be susceptible to degradation from oxygen and light, appropriate packaging and stabilization strategies are recommended to maintain ingredient integrity.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

Mentha Suaveolens Leaf Extract is widely recognized as safe for use in cosmetic products and has received approval from regulatory authorities such as the European Cosmetics Regulation. While generally well-tolerated, some individuals with sensitive skin may experience mild allergic reactions, making a sensitivity test advisable. The EWG Skin Deep database rates this ingredient with a low hazard for cancer, developmental and reproductive toxicity, and use restrictions. Although this specific extract has not been reviewed by CIR, related ingredients like Mentha piperita Leaf Extract have been deemed safe for cosmetic use with restrictions on menthol and pulegone content (pulegone not exceeding 1%).
