Helichrysum Arenarium Extract
Helichrysum arenarium (sand everlasting / dwarf everlasting) extract is derived from a flowering Asteraceae plant native to Europe and Central Asia, distinct from H. italicum (immortelle). Its unique phytochemicals — arenariumosides I–IV (species-specific TNF-alpha inhibitors), isosalipurposide (dominant chalcone), and flavones (apigenin, galangin, kaempferol) — deliver potent anti-inflammatory activity comparable to indomethacin in vivo, antioxidant and UV photoprotection, and documented anti-sebum effects (EU CosIng REF 34242, CAS 85665-35-6). A protected species in some European countries; verify sustainably sourced material.
Also known as: sand everlasting extract, dwarf everlasting extract

Benefits
- ✓Arenariumosides I–IV (species-unique TNF-alpha inhibitors) and naringenin suppress MAPK/JNK2/p38 and NF-κB inflammatory pathways — documented topical anti-inflammatory potency comparable to indomethacin in vivo
- ✓Isosalipurposide (dominant chalcone) and the flavone-rich fraction (apigenin, galangin, kaempferol) provide strong UV-absorbing antioxidant protection; confirmed photoprotective in UVA+UVB emulsion testing
- ✓Official EU CosIng anti-sebum function confirmed; galangin and apigenin flavone profile associated with sebum reduction, making this relevant for oily and combination skin formulas
Watch for
- ⚠Asteraceae/Compositae family — patch test recommended for individuals with known daisy or ragweed sensitization
- ⚠Conservation note: H. arenarium is a protected or endangered species in several European countries — verify sustainably cultivated sourcing before use
- ⚠Distinct from Helichrysum italicum (immortelle) — different phytochemical profile, not interchangeable
