Polygonum Cuspidatum Root Extract
It is extracted from the Japanese knotweed, known in Traditional Chinese Medicine as Hu Zhang, this plant not only helps thwart free radicals before they can damage skin, it also reduces signs of irritation. This plant extract can also inhibit the formation of advanced glycation end-products, or AGEs. AGEs are collagen-damaging proteins and fats that are formed as a reaction from exposure to sugars within the skin. Left unchecked, AGEs can lead to premature skin aging.
