Science
Mechanism of Action
This extract precisely targets key proteins such as elastin and fibrillin-1, enhancing their expression to support the synthesis and maintenance of functional elastic fibers, thereby improving skin elasticity and firmness. It is abundantly rich in antioxidants, including a spectrum of alkaloids and flavonoids, which robustly counteract oxidative stress and fortify the skin's natural barrier. Furthermore, the extract demonstrates antimicrobial, anti-inflammatory, and skin-healing capabilities, aids in the gentle removal of dead skin cells, and stimulates cellular regeneration and renewal. Ancillary actions may include anti-hyaluronidase activity, moisturizing, depigmentation, and photoprotection.

The Formula
Formulation
Stability
While acidic pH conditions may enhance the antioxidant activity of ethanolic extracts, formulators should avoid using extraction solvents containing salts or acids. Traces of these can complicate the formulation of gels or emulsions when the extract concentration exceeds 0.1%.
Conflicts
- Traces of salts or acids from extraction solvents can negatively impact the formulation of gels or emulsions at concentrations above 0.1%.
Safety
Safety Profile
Murraya Koenigii Leaf Extract has not undergone formal review by major regulatory bodies such as CIR, SCCS, or FDA. Although a face wash containing the extract was deemed safe and non-irritant in a study, the presence of alkaloids in Murraya Koenigii suggests that careful management of its concentration in cosmetic formulations is advisable due to the potential for acute toxicity in purified forms or chronic toxicity at lower doses.
