Science

Mechanism of Action

The dual action of this ingredient is derived from its two primary components. Lactobacillus ferment actively fortifies the skin's protective barrier and aids in restoring a balanced microflora, thereby mitigating irritation, reducing redness, and stimulating natural skin renewal. It also acts as a humectant and antioxidant, supporting DNA repair and providing anti-microbial and anti-inflammatory benefits. Concurrently, the Citrus Aurantium Dulcis Peel Extract, enhanced by fermentation, delivers a rich array of antioxidants to neutralize free radicals, exhibits antiseptic qualities to reduce inflammation, and offers gentle exfoliation through natural fruit acids. Its polysaccharide/amino acid complex further ensures essential hydration and helps regulate oil production for balanced skin.

Stability

This ingredient is designed for thermal stability, allowing its addition to the water phase at temperatures up to 70-75°C. While lower temperatures may induce cloudiness, this does not compromise its activity or efficacy. For optimal formulation stability and to maintain a slightly acidic pH, the use of nonionic emulsifiers is recommended.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Moderate

The CIR Expert Panel deems both Lactobacillus ferment and citrus peel-derived ingredients safe for cosmetic use, provided specific formulation guidelines are followed. For leave-on citrus products, the concentration of the phototoxic compound 5-MOP should not exceed 0.0015% (15 ppm). It's important to note that Lactobacillus ferment components may exhibit skin lightening effects through tyrosinase inhibition; formulators should ensure this effect aligns with product intent to avoid unintended depigmentation. The Citrus Aurantium Dulcis Fruit Extract component can potentially induce irritation or allergic reactions in sensitive individuals. Furthermore, due to its inherent photosensitivity, daily sunscreen application is strongly advised when incorporating products containing this extract into a daytime routine. A preliminary sensitivity test is recommended prior to widespread application.
