Epilobium Angustifolium Flower/Leaf/Stem Extract
Epilobium Angustifolium Flower/Leaf/Stem Extract is a whole-plant extract from fireweed (also known as rosebay willowherb), derived from flowers, leaves, and stems. The key bioactive is oenothein B, a dimeric ellagitannin that has been extensively studied as a 5α-reductase inhibitor (reducing sebum production) and anti-inflammatory. The extract also contains flavonoids and phenolic acids with antioxidant activity. Used in Korean cleansing and sensitive-skin formulas targeting oil control and inflammation.
