What Is Epilobium Angustifolium Extract?
Epilobium angustifolium extract is obtained from a flowering plant known in North America as fireweed and in parts of the United Kingdom as rosebay willowherb. It’s well known in folk medicinefor its soothing properties and has been used topically for centuries to treat rashes, burns, and other skin ailments.
As it turns out, the traditional foundation for this application is solid: modern research demonstrates fireweed extract is an excellent addition to skin care. Fireweed contains an abundance of antioxidant polyphenols, is a source of l-ascorbic acid (pure vitamin C), and contains fatty acids, among them oleic and palmitic acids. These antioxidant and moisturizing properties give the extract a wealth of anti-ageing benefits.
In addition, studies show Epilobium angustifolium extract has strong anti-inflammatory properties (mainly from its polyphenol content), giving it value in skin care preparations designed to soothe skin or tamp down redness.
Typically supplied in a water base, Epilobium angustifolium extract’s use level in cosmetics hovers between 0.5–1.5%. If used in more concentrated powder form, the use level would drop to 0.1% or less.
In short, Epilobium angustifolium extract is a multifaceted ingredient that is a welcome addition to any skin care product!
