Science
Mechanism of Action
Lindera Strychnifolia Leaf Extract functions as a robust antioxidant by actively neutralizing reactive oxygen species (ROS) like hydroxyl (•OH) and superoxide (O2•−) radicals, and reactive nitrogen species (NOS) such as nitric oxide (NO•), thereby safeguarding cellular integrity from oxidative stress and inhibiting lipid peroxidation. Its anti-inflammatory capabilities aid in soothing skin irritations. Furthermore, it modulates melanogenesis by downregulating MITF and tyrosinase, resulting in a reduction of hyperpigmentation. Beyond these actions, the extract promotes overall skin vitality, leading to softening and a decrease in the appearance of wrinkles.
