Fragrance ingredient
Citrus Junos Peel Oil
Cold-pressed essential oil from the peel of Citrus junos (yuzu), a citrus fruit widely cultivated in East Asia. Composed primarily of d-limonene (63–92%) and γ-terpinene; furanocoumarins (bergapten) are below detection limit (<0.1 ppm) in commercial cold-pressed yuzu peel oil — well under the 15 ppm cosmetic safety threshold — so phototoxicity is not a concern. Primary allergen risk is limonene, which is an EU-regulated fragrance allergen under Regulation 2023/1545 and must be declared on leave-on products above 0.001%. Vitamin C and brightening benefits associated with yuzu belong to aqueous yuzu fruit extract forms, not this essential oil.
Also known as: yuzu peel oil, yuzu oil

Watch for
- ⚠Limonene (63–92% of the oil) is an EU-mandated fragrance allergen (Regulation 2023/1545); must be declared on leave-on product labels above 0.001%
- ⚠Oxidized limonene is a stronger sensitizer than fresh; finished products should have peroxide value <20 mmol/L
- ⚠Citral present at trace levels — declarable EU allergen if above threshold; may cause sensitization in fragrance-sensitive individuals
