Antioxidant ingredient
Mallotus Japonicus Leaf Extract
Mallotus japonicus leaf extract (EU CosIng REF 82898) is derived from the leaves of akamedoki/akamegashiwa, a deciduous East Asian tree in the Euphorbiaceae family. Its phytochemical profile — ellagitannins (mallotinic acid, mallotusinic acid, corilagin, geraniin) and the dominant flavonoid rutin — delivers EGCG-equivalent antioxidant activity, tyrosinase-inhibiting brightening, and iNOS/NO-suppressing anti-inflammatory properties. Sourced from Jeju Island (Korea); listed in EU CosIng for antioxidant, antimicrobial, and skin-protecting functions.
Also known as: Akamegashiwa leaf extract, Jeju Mallotus Extract

Benefits
- ✓Exceptional antioxidant potency from ellagitannins (mallotinic acid, mallotusinic acid, corilagin, geraniin) — EGCG-equivalent DPPH/superoxide radical scavenging that outperforms green tea and rooibos in comparative assays
- ✓Rutin (dominant flavonoid) inhibits tyrosinase and suppresses melanin synthesis in B16 melanoma cells dose-dependently, providing a secondary brightening benefit against UV-induced pigmentation
- ✓Corilagin and ellagitannins suppress iNOS induction and reduce nitric oxide in activated macrophages, contributing anti-inflammatory and anti-glycation activity
Watch for
- ⚠No CIR safety review; limited published topical irritancy data. Edible plant in Japan provides broad background safety context
- ⚠Euphorbiaceae family plant — rare contact sensitization possible; patch test recommended for sensitive skin
Compatibility
✓ Works well with
