Epilobium Angustifolium Flower/Leaf/Stem Extract
Discover the soothing and balancing power of Epilobium Angustifolium. Our standardized extract, featuring key actives like Oenothein B, flavonoids, and phenolic acids, is supplied as a standard or concentrated hydroglycerin stock, distinguishing it from general Canadian Willowherb or Fireweed raw materials.
Canadian Willowherb · Fireweed
Botanical Identity: Derived from the resilient *Epilobium Angustifolium* plant, also commonly known as Canadian Willowherb, Fireweed, or simply Willowherb. Our Product: We provide the pure botanical extract, identified by its INCI name Epilobium Angustifolium Flower/Leaf/Stem Extract, distinct from various supplier-specific trade names or branded ingredients.
Dual mechanism: The cosmetic activity of Epilobium Angustifolium Flower/Leaf/Stem Extract is multi-faceted, driven by its rich polyphenol profile, primarily the macrocyclic ellagitannin Oenothein B. It acts as a potent inhibitor of 5-α-reductase, helping to balance surface oils, and suppresses inflammatory pathways by inhibiting lipoxygenase and cyclooxygenases (COX-1 and COX-2) to reduce visible erythema and irritation. Furthermore, it supports the skin's structural matrix by inhibiting matrix metalloproteinases (MMPs) like collagenase, elastase, and hyaluronidase, contributing to the appearance of skin firmness and texture. Additional benefits include direct antioxidant activity against reactive oxygen species (ROS) and antibacterial properties against microbes relevant to blemishes, such as *P. acnes*.
Use levels: For optimal efficacy, particularly for rapid anti-erythema effects, Formulate Labs' standardized hydroglycerin stock is typically incorporated into formulations at a rate of 1.0% to 5.0%. Optimal results are often observed between 1.0% and 3.0%.
Market context: Epilobium Angustifolium Flower/Leaf/Stem Extract is a versatile active competing in the high-performance botanical space. Products in this category are often positioned for rapid anti-irritant effects, with claims around reducing visible redness from chemical or UV exposure. Others emphasize lipid-soluble properties for biomimetic skin barrier support and protection from oxidative stress, while some are aggressively marketed for managing hyperseborrhoea and blemishes through potent anti-androgenic and antimicrobial activity.

Epilobium Angustifolium Flower/Leaf/Stem Extract delivers multi-faceted cosmetic activity, primarily driven by its rich profile of polyphenols, including the macrocyclic ellagitannin Oenothein B, alongside supportive flavonoids and phenolic acids. This potent peptide addresses key concerns related to skin irritation, blemishes, and overall structural integrity. It functions as a powerful inhibitor of 5-α-reductase, an enzyme critically linked to sebum production, thereby helping to balance surface oils on both skin and scalp. For soothing applications, it actively suppresses inflammatory pathways by inhibiting lipoxygenase and cyclooxygenases (COX-1 and COX-2), leading to a visible reduction in erythema and sensations of irritation. Furthermore, its ability to inhibit matrix metalloproteinases (MMPs) such as collagenase, elastase, and hyaluronidase helps preserve the appearance of skin firmness and texture, supporting the skin’s structural matrix. These actions are complemented by direct antioxidant activity through the neutralization of reactive oxygen species (ROS) and antibacterial properties against microbes like P. acnes, making it exceptionally well-suited for formulations targeting oily, blemish-prone, and sensitive skin.
Market context: Epilobium Angustifolium Flower/Leaf/Stem Extract is a highly competitive, multi-functional active that stands alongside other high-performance botanicals in the market. Actives found in Canadian Willowherb™-class products are often recognized for their rapid anti-irritant effects, specifically reducing visible redness from chemical or UV exposure. The extract found in EPILOBIUM Oléoactif®-class actives, differentiated by a patented oil-based extraction, emphasizes lipid-soluble benefits for barrier reinforcement and moisturization. Meanwhile, the extract found in Seborilys-class actives typically appears in synergistic botanical blends, marketed for aggressive management of hyperseborrhoea and blemishes through potent anti-androgenic and antimicrobial activity. Formulate Labs offers Epilobium Angustifolium Flower/Leaf/Stem Extract as a versatile and standardized raw material, distinct from these branded end-products.
Formulate Labs provides Epilobium Angustifolium Flower/Leaf/Stem Extract in a cosmetic-grade hydroglycerin base, meticulously standardized for its Oenothein B content.
