Science
Mechanism of Action
This ingredient utilizes a three-tiered approach to skin health: first, mild citric and malic acids provide enzymatic exfoliation to encourage cellular turnover; second, a high concentration of flavonoids (hesperidin, naringin) and vitamin C neutralize oxidative stress and support the collagen matrix; and third, natural polysaccharides like pectin act as humectants to maintain epidermal hydration levels.

Dusting Analysis
Often included at very low levels (below 0.1%) primarily for label appeal or fragrance support. For genuine exfoliating and antioxidant benefits, concentrations should ideally exceed 1% in rinse-off or leave-on formulations.
The Formula
Formulation
Stability
Maintains peak efficacy and stability within a slightly acidic window (pH 4.0–6.0). Formulators must monitor furocoumarin levels, specifically 5-MOP, to ensure the product remains non-phototoxic.

Safety
Safety Profile
While generally recognized as safe, leave-on formulations must strictly limit 5-methoxypsoralen (5-MOP) to 15 ppm to mitigate any phototoxicity risks. It is non-irritating when formulated correctly.
