Science
Mechanism of Action
This ingredient delivers a spectrum of beneficial components including flavonoids, terpenes, linalool, vitamin C, and folic acid, which collectively provide significant antioxidant protection. Polymethoxyflavonoids (PMFs), notably nobiletin and tangeretin, are particularly effective in suppressing matrix metalloproteinase production and reducing UV-induced inflammation, contributing to an even skin tone. It also functions as a skin conditioning agent by supporting skin elasticity and reducing flakiness in dry or damaged skin, while its essential oil constituents possess antimicrobial effects.

The Formula
Formulation
Stability
The active flavonoid components are effectively extracted and demonstrate stability in aqueous and aqueous ethanol solutions, making it suitable for water-based formulations.
Conflicts
- High concentrations of furocoumarins, such as 5-methoxypsoralen (5-MOP), can lead to photosensitization in leave-on products and must be strictly controlled.
- Constituents like limonene and citral, commonly found in citrus extracts, may pose a sensitization risk if not properly managed.
- Requires adherence to good manufacturing practices to ensure the absence of pesticide residues and heavy metals.
Safety
Safety Profile
The CIR Expert Panel concludes Citrus peel-derived ingredients are safe for cosmetic use when formulated to be non-sensitizing and non-irritating. For leave-on products, the concentration of the photosensitizing compound 5-methoxypsoralen (5-MOP) must not exceed 0.0015% (15 ppm). Some Citrus peels and their extracts are recognized as Generally Recognized As Safe (GRAS) by the U.S. FDA for food applications.
