What it is
Epilobium fleischeri is a willowherb species native to high-altitude alpine habitats, and its extract is added to formulas as a plant-derived conditioning ingredient. Like other Epilobium species, it is associated with polyphenolic constituents and is positioned in cosmetics for its soothing feel on the skin. In sunscreens it functions as a supporting botanical rather than as a UV filter.
Safety & warnings
As a botanical extract it is generally well tolerated at cosmetic use levels, though plant extracts can occasionally provoke sensitivity in individuals predisposed to botanical allergies. It is not an oil and is not associated with comedogenicity.
Origin & sourcing
Botanical, obtained from the aerial parts of the alpine plant Epilobium fleischeri.
