About this ingredient

Artemisia Absinthium Extract is derived from the aerial parts of Artemisia absinthium (wormwood) by alcohol or CO2 extraction. It contains sesquiterpene lactones (absinthin, artabsin), an essential oil with thujone (alpha- and beta-thujone), flavonoids, and phenolic acids. The main functional components are the bitter lactones and thujone. Where it is used. Toners and products for oily and acne-prone skin, scalp lotions for seborrhea, hair products, aromatherapy blends, and traditional European and Mediterranean formulas. Concentrations 0.1-2%. In Spain – niche natural brands and traditional phytocosmetics. Mechanism. Sesquiterpene lactones inhibit Cutibacterium acnes and Staphylococcus aureus growth, making the extract an antibacterial component in acne formulas. Thujone at low concentrations acts as a toning, warming agent and dilates surface capillaries. Flavonoids scavenge free radicals. Phenolic acids give an astringent effect on enlarged pores. Thujone controversy. Thujone is a neurotoxin at high systemic doses. The historical association with absinthe (banned in many countries from the early 20th century) and epileptogenic action with abuse is well known. EU and FDA limit thujone in cosmetics and food: leave-on cosmetics may contain up to 0.04% free thujone under EU Cosmetic Regulation 1223/2009. In properly standardized extracts, thujone concentration is safe. Evidence base. Topical wormwood – evidence base C-D. In vitro antimicrobial data confirm activity against bacteria and fungi (Msaada 2015), but clinical studies in acne or seborrhea are lacking. The natural antiseptic marketing claim is scientifically limited. Safety. PREGNANCY – CAUTION. Thujone has abortifacient effects at high systemic doses (folk use of wormwood for pregnancy termination is documented in ethnopharmacology). Topical use below 2% is theoretically safe, but during the first trimester products with wormwood on large skin areas are best avoided. Breastfeeding – also with caution. Allergic contact dermatitis is described in patients sensitized to Compositae plants – cross-reaction with ragweed, chamomile, and pyrethrum. Practical notes. Not a first-line option for acne or seborrhea – alternatives with a better safety profile and stronger evidence exist (niacinamide, azelaic acid, zinc). Appears sporadically in niche natural lines. During pregnancy and breastfeeding, replace with safer alternatives (centella, bisabolol, niacinamide).
