Science
Mechanism of Action
This extract leverages its high content of citric acid to gently exfoliate the skin, effectively aiding in the removal of surface debris, excess oils, and environmental pollutants. Its Vitamin C content acts as a potent antioxidant, neutralizing free radicals and supporting the appearance of firmer, tighter skin. Further antioxidant benefits are derived from its carotenoids, phenolics, and flavanones, while essential oil components contribute to potential antimicrobial activity against certain yeasts.

Stability
While no specific optimal pH range for the stability of the fruit extract in cosmetic formulations was identified, the natural pH of clementine fruit itself typically ranges from 3.01 to 3.43.
Conflicts
- Sensitive skin (due to its inherent acidic and exfoliating nature)
- Dry skin (due to its inherent acidic and exfoliating nature)
- Sunlight exposure (requires careful formulation to minimize potential photosensitivity, particularly related to furanocoumarins like 5-methoxypsoralen)
Safety
Safety Profile
The U.S. FDA recognizes Citrus fruits and their derived extracts as Generally Recognized As Safe (GRAS) for food use. The Cosmetic Ingredient Review (CIR) Expert Panel deems Citrus Clementina Fruit Extract safe for cosmetic use, provided formulations are non-sensitizing and non-irritating. A critical restriction for leave-on products is the maximum presence of 5-methoxypsoralen (5-MOP), a furanocoumarin, which should not exceed 0.0015% (15 ppm) due to its potential to cause photosensitivity.
