Echinacea is a perennial herbaceous plant belonging to the genus Echinacea within the Asteraceae family; native to North America, it derives its name from its distinctive purple, cone-shaped floral disk. As early as several centuries ago, Native Americans utilized it to treat wounds, address insect bites, and alleviate inflammation-a rich history of traditional medicinal use that has laid the foundation for its development in modern skincare products. Echinacea extract powder is produced by extracting the plant's active constituents using solvents-such as ethanol-followed by purification and drying processes to yield a fine powder.
The echinacea purpurea extract powder produced by KINTAIBIO® is extracted using food-grade solvents-such as ethanol and purified water-via a constant-temperature reflux process. It subsequently undergoes filtration, concentration, and spray-drying to yield a standardized powder. The product presents as a fine powder ranging in color from light brown to brown. Various specifications are available to meet client requirements, including total phenol content of 2% (detected via HPLC) or 4% (detected via UV), and chicoric acid content of 1%, 2%, or 4% (detected via HPLC). This product is widely applicable in fields such as skincare and cosmetics.please feel free to contact our sales team: sales@kintaibio.com.
How Echinacea Extract Works for skin: Mechanisms of Action and Chemical Targets
Inhibition of Lipoxygenase and Cyclooxygenase
Echinacea extract directly inhibits the activity of 5-lipoxygenase (5-LOX), thereby reducing the synthesis of potent inflammatory mediators such as leukotrienes. Simultaneously, it inhibits cyclooxygenase (COX) activity-reducing prostaglandin synthesis-thereby blocking multiple inflammatory pathways at their enzymatic source. In vitro studies have demonstrated that Echinacea Purpurea extract can reduce the levels of IL-6 released by inflammatory cells by 30%–50%.
Reduction of Pro-inflammatory Cytokine Expression and Release in Keratinocytes
Echinacea extract significantly reduces both the mRNA expression levels and protein release of the pro-inflammatory cytokines IL-6 and IL-8 in poly(I:C)-stimulated keratinocytes. In acne models, microbial stimulation induces the copious secretion of IL-6 and IL-8; echinacea purpurea extract powder completely reverses this effect, restoring cytokine levels to their normal baseline range.
Alleviation of Immediate Hypersensitivity Reactions
Volatile oils and terpene components act upon mast cells to inhibit the release of β-hexosaminidase (a marker enzyme for mast cell degranulation) and reduce histamine release. This effectively alleviates allergic symptoms-such as skin redness, burning sensations, and itching-at their source. Studies have shown that Echinacea extract can mitigate the itching and erythema induced by histamine release.

Reduction of TNF-α and PGE-2 Expression
The alkylamide components downregulate the phosphorylation of p38, ERK 1/2, and STAT 3, as well as the NF-κB signaling pathway. This leads to a reduction in the expression of cyclooxygenase-2 (COX-2) and, consequently, a decrease in PGE-2 synthesis; simultaneously, it inhibits the expression of TNF-α. TNF-α serves as a critical initiator of the inflammatory cascade, acting synergistically with PGE-2 to drive skin inflammation and pain sensitization.
Scavenging of DPPH Free Radicals; Antioxidant and Anti-photoaging Effects
Echinacea Purpurea extract is rich in polyphenolic and flavonoid compounds. DPPH free radical scavenging assays have demonstrated that its ORAC antioxidant activity value can reach approximately 15,000 μmol TE/g. Cichoric acid itself possesses potent antioxidant properties; it effectively neutralizes free radicals and mitigates DNA damage to skin cells caused by ultraviolet radiation and environmental pollution. Furthermore, the ethanolic extract derived from Echinacea exhibits significantly stronger antioxidant activity than its aqueous counterpart, demonstrating superior free radical scavenging capabilities and ferric-reducing antioxidant power (FRAP).
Enhancing Epidermal Total Lipid, Ceramide, and Cholesterol Content
A double-blind clinical study revealed that after 15 days of applying a cream containing Echinacea extract, subjects demonstrated significantly higher levels of total epidermal lipids, ceramide EOS, and cholesterol compared to baseline levels; additionally, the number of intercellular lipid lamellae within the intercellular spaces increased significantly. Ex vivo skin model studies further indicated that echinacea purpurea extract powder upregulates the expression of the tight junction protein Claudin-1 by approximately 27%, thereby further reinforcing the skin's physical barrier function.
Protective Effects Against Ultraviolet Radiation
Echinacoside, a constituent of Echinacea, can ameliorate UVB-induced skin damage by selectively inhibiting TRPV3 channels within the skin. Echinacea extract powder reduces DNA strand breaks in skin cells, lowers the risk of post-sunburn erythema and hyperpigmentation, and simultaneously protects dermal collagen from oxidative degradation. Cichoric acid itself also plays a protective role against UV-induced skin damage and supports the skin's natural defense mechanisms.
echinacea purpurea extract skin benefits
Anti-Aging and Early Aging Prevention
The flavonoid components within Echinacea purpurea extract inhibit the activity of collagenase and elastase, thereby reducing collagen loss. Its polysaccharide components promote fibroblast proliferation and enhance skin elasticity. It offers dual protection against photoaging through free radical scavenging and anti-inflammatory mechanisms, and provides neuroprotection via the TRPV3 channel pathway.
Skin Barrier Repair
Echinacea extract increases the epidermal content of total lipids, ceramides, and cholesterol. It enhances the quantity of intercellular lipid lamellae and upregulates the expression of tight junction proteins. Its polysaccharide molecules, structurally similar to the skin's natural moisturizing factors, form a protective film that locks in moisture. This action safeguards the stability of the sebum film and reduces transepidermal water loss (TEWL).

Soothing and Anti-Inflammatory Effects
Echinacea purpurea powder extract also inhibits lipoxygenase activity and histamine release. It downregulates the expression of IL-6, IL-8, TNF-α, and PGE-2. In tissue culture models, Echinacea extract has been shown to alleviate inflammatory edema in a dose-dependent manner. It is suitable for use on sensitive skin to reduce redness, relieve itching, and assist in the management of chronic inflammation.
Water-Oil Balance and Acne Control
The phenolic acid components of Echinacea extract powder regulate sebum secretion and inhibit the proliferation of microorganisms such as Propionibacterium acnes. Its polysaccharide components provide hydration and moisturization, thereby maintaining the skin's water-oil balance. Echinacea extract can completely reverse acne-related secretion of IL-6 and IL-8, restoring cytokine levels to their normal baseline.
Promoting Wound Healing and Tissue Repair
Echinacoside, a key constituent, promotes keratinocyte proliferation and migration by activating the ERK signaling pathway; in vitro scratch assays have demonstrated that it accelerates wound closure by 20–30% compared to control groups. Studies have confirmed that Echinacea ethanol extract significantly improves wound healing capacity in animal models, while simultaneously downregulating IL-6 expression, upregulating IL-10 expression, and promoting angiogenesis and collagen deposition. Furthermore, it protects fibroblasts from oxidative damage and facilitates the formation of granulation tissue.
Whitening and Brightening
Tissue-cultured Echinacea extract can inhibit melanin synthesis in B16 melanoma cells in a dose-dependent manner while simultaneously scavenging free radicals; it also inhibits tyrosinase activity.
