Science
Mechanism of Action
This extract operates via multiple pathways: it effectively neutralizes reactive oxygen species (ROS) to mitigate oxidative stress, a primary driver of skin aging. Furthermore, it demonstrates anti-inflammatory action and inhibits matrix metalloprotease-1 (MMP-1), an enzyme implicated in collagen breakdown. Key constituents such as thymol and carvacrol provide additional antimicrobial benefits, contributing to its efficacy in anti-acne and soothing formulations.
