Summary

Antioxidant Skin-brightening Anti-inflammatory Anti-aging Moisturizing Photoprotective Anti-allergic Antimicrobial

Science

Mechanism of Action

This extract functions as an anti-inflammatory agent by inhibiting nitric oxide (an inflammatory substance) and through the activity of coumarins. Its rich composition of flavonoids, carotenoids, and coumarins provides robust antioxidant protection against free radicals and oxidative stress. It enhances skin moisturization by stimulating hyaluronic acid production and acts as a skin brightening agent by inhibiting tyrosinase, an enzyme crucial for melanin synthesis. Additionally, it exhibits photoprotective effects against UVA-induced photoaging and possesses anti-allergic properties that can help mitigate symptoms of atopic dermatitis, with potential antimicrobial benefits.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The CIR Expert Panel deems citrus-derived ingredients, including Citrus Unshiu Fruit Extract, safe for use in both rinse-off and leave-on cosmetic products, provided they are formulated to be non-sensitizing and non-irritating. For leave-on applications, the concentration of 5-methoxypsoralen (5-MOP) must not exceed 0.0015% (15 ppm) to mitigate potential photosensitization. Manufacturers are advised to control levels of botanical constituents such as limonene, citral, monoterpenes, and furocoumarins to prevent sensitization. Topical exposure to a 0.5% Citrus Unshiu Peel Extract formulation demonstrated no irritation in human subjects.
