Plant extracts allow us to harness the power of nature for our benefit. These extracts are traditionally obtained from dried plant material. Carotenoids, menthol, flavonoids, glycyrrhizin, caffeine, and even essential oils are examples of such natural active ingredients. Used both internally and externally, they offer a multitude of benefits. Some have a calming effect, some offer oxidative protection, and some provide important nutrients for the body. In skincare products, they promote a healthy appearance of the skin.
