Citrus reticulata (mandarin/tangerine) peel extract or oil is derived from mandarin orange and used in skincare as a natural fragrance, antioxidant, and skin-conditioning agent. It contains limonene and other terpenes that contribute its citrus scent and provide mild antioxidant activity.

| Allergic contact dermatitis | Uncommon | Sensitization linked to limonene and other terpene components, especially when oxidized. |
| Phototoxicity/photosensitivity | Rare | Cold-pressed citrus peel oils may contain furocoumarins; expressed oils carry greater risk than steam-distilled forms. |
