Ingredient review
Siberian Motherwort Seed Extract
INCI: Leonurus Sibiricus Seed Extract
A gentle, antioxidant-rich plant extract that may help calm skin and fight free radical damage, though research is still early.
In plain English
Siberian motherwort seed extract comes from the seeds of a plant traditionally used in herbal medicine. In skincare, it is added for its ability to neutralize unstable molecules called free radicals, which can damage skin cells and speed up aging. It also has mild soothing properties, meaning it may help reduce redness or irritation. Because it is a natural extract, its effects can vary depending on how it is processed and formulated into a product.
