Can I use Epigallocatechin Gallate with Helichrysum Arenarium Extract?
Works well together
Epigallocatechin Gallate and Helichrysum Arenarium Extract are generally compatible and can be layered in the same routine. As always, introduce one new active at a time and watch how your skin responds.
Epigallocatechin GallateAntioxidant
- ✓The most potent catechin in green tea — scavenges free radicals with significantly higher antioxidant activity than vitamins C and E
- ✓Inhibits metalloproteinases (MMPs) that degrade collagen, providing a mechanism for anti-photoaging activity
- ✓Anti-inflammatory activity via NF-κB and MAPK pathway modulation — reduces UV-induced erythema and inflammatory markers
Helichrysum Arenarium ExtractSoothing
- ✓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
- ⚠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
