What is Artemisia Capillaris?
Artemisia Capillaris is a perennial plant with extract that is becoming popular in skin care. There are over 500 species of the genus Artemisia (of the Astraceae or Compositae family) dispersed throughout the temperate areas of Asia, Europe, and North America.[iii] Various parts of A. capillaris have been used in traditional medicine in Asia for hundreds of years.
If you’re just looking for the best products with artemisia capillaris, here are my favorites:
Active compounds in artemisia capillaris
Flavonoids (e.g., quercetin, luteolin) : These phenolic compounds express strong antioxidant properties, protecting the skin from free radicals and inflammation.
Unique compounds (e.g., capillin, capillene) : These oils have antimicrobial and anti-inflammatory benefits, soothing irritated skin and reducing acne causing bacteria.
Coumarins (e.g., esculetin) : Coumarins stimulate collagen production and inhibit tyrosinase, an enzyme involved in melanin production.
Phenolic acids (e.g., caffeic acid) : These acids have antioxidant properties and anti-inflammatory benefits. They’re also good for soothing redness.
Polysaccharides : They offer moisturizing properties, improving skin hydration and barrier function.
Triterpenoids (e.g., ursolic acid) : These compounds have anti-inflammatory and anti-aging effects, promoting collagen production and improving skin elasticity.
Fatty acids (e.g., linoleic acid) : Essential for maintaining the skin’s lipid barrier, they help in retaining moisture and protecting against environmental factors like pollution, dirt, etc.

Safety Issues and Clean Ingredient Standards for Artemisia Capillaris
Artemisia capillaris is generally recognized as safe (GRAS). There are no clean ingredient standards that exclude A. capillaris.
The CIR (Cosmetic Ingredient Review Panel) has graded Artemisia Capillaris (AKA Wormwood) “safe” in skin care formulations.
Environmental impact
Artemisia Capillaris is a sustainable ingredient for use in skin care products. It does not have any particular or unique side-effects on the environment. It does not take a lot of water to grow mugwort and it is fast growing.
Studies on Artemisia Capillaris
Artemisia capillaris limits the expression of tyrosinase-related protein 1 (TYRP-1), which is structurally comparable to tyrosinase. TYRP-1 is involved in eumelanin (the most common form of melanin, including brown and black) synthesis, but not in pheomelanin (responsible for yellowish to reddish tints) synthesis. TYRP-1 is being looked at as a target for treatment of hyperpigmentation disorders such as melasma; therefore, A. capillaris is considered attractive for use in skin-lightening products.
In a 2022 study, A. capillaris was among four essential oil extracts (of 10 studies) to suppress the development of melanin in a B16F10 cell line model.[xiv] Six years earlier, the A. capillaris constituent 4,5-O-dicaffeoylquinic acid significantly and dose-dependently reduced melanin production and tyrosinase activity in melanocytes and decreased the expression of TYRP-1 in mouse cultured cells.[xv]
Conclusion
Artemisia capillaris has long been used in traditional medicine in Asia. It appears to have potential in skin care creams or other products to treat dry skin, eczema, psoriasis, rosacea, melasma, and sensitive skin.
