Science
Mechanism of Action
This peel powder, or its extracts, delivers revitalization through a rich profile of Vitamin C and various antioxidants, stimulating collagen synthesis to refine skin texture and diminish visible signs of aging. Its inherent antibacterial compounds help to mitigate acne and related skin issues, complemented by sebum-regulating capabilities that prevent imperfections like blackheads. Furthermore, the presence of monoterpenes and flavonoids confers anti-inflammatory benefits, effectively soothing redness and discomfort, while also regulating skin moisture for enhanced hydration, softening, and overall skin comfort.

The Formula
Formulation
Stability
Formulators must exercise caution due to constituents such as limonene, citral, monoterpenes, and furocoumarins (e.g., 5-methoxypsoralen or 5-MOP), which are known to potentially cause sensitization or adverse reactions. Careful manufacturing practices are imperative to minimize impurities like pesticide residues and heavy metals. Furanocoumarins specifically may induce mild phototoxicity, especially in leave-on products intended for daytime use, necessitating precise formulation to maintain very low levels.
Safety
Safety Profile
The CIR Expert Panel deems citrus peel-derived ingredients, including Citrus Tachibana/Reticulata Peel Powder, safe for cosmetic use in both rinse-off and leave-on products, provided they are formulated to be non-sensitizing and non-irritating. A critical restriction for leave-on products mandates the 5-methoxypsoralen (5-MOP) content not to exceed 0.0015% (15 ppm). The SCCS identifies certain citrus constituents as established contact allergens, and European Union regulations stipulate that furocoumarin levels in sun-protection and bronzing products must be below 1 mg/kg. The FDA generally recognizes some citrus peels and extracts as safe (GRAS) for food applications, but cosmetic use requires careful consideration of specific constituent concentrations.
