Citrus paradisi (Grapefruit) Extract is derived from grapefruit fruit and peel, providing antioxidants (flavonoids, vitamin C) and natural fragrance in skincare formulations. It is sometimes used for its purported toning and brightening properties.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation or stinging | Common | Citrus extracts and their acidic components can irritate sensitive or compromised skin. |
Allergic contact dermatitis | Uncommon | Limonene and other fragrance constituents are known sensitizers. |
Phototoxicity / photosensitivity | Uncommon | Citrus peel-derived furocoumarins may increase sun sensitivity, though fruit extracts typically contain lower levels than expressed peel oils. |
Hyperpigmentation following sun exposure | Rare | Phototoxic reactions can leave residual darkening of the skin. |
Systemic or severe reactions | Very rare | Generally limited to topical exposure; serious effects are not typically reported. |
