Science
Mechanism of Action
This dipeptide primarily leverages the benefits of arginine. Arginine functions as a precursor for nitric oxide (NO), enhancing microcirculation and oxygen delivery, which is critical for stimulating tissue repair and wound healing. It actively promotes collagen synthesis, crucial for maintaining skin elasticity and reducing the visibility of fine lines and wrinkles. As a key component of the skin's Natural Moisturizing Factor (NMF), arginine effectively attracts and retains water, significantly improving skin hydration and reinforcing the skin barrier. Furthermore, it exhibits antioxidant properties, neutralizing free radicals and safeguarding against oxidative stress. The aspartate component is believed to support cellular energy metabolism through its participation in the Krebs cycle, aiding overall cellular regeneration and protein structure.

Stability
Arginine, a constituent of Arginine Aspartate, can function as a pH regulator. Its solubility and thermal stability are influenced by pH, with higher solubility noted at lower pH (5-6) for related therapeutic proteins. However, explicit optimal pH ranges for the stability of Arginine Aspartate as a cosmetic ingredient are not defined.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed alpha-amino acids, including Arginine, safe for cosmetic use at concentrations up to 18%. The FDA classifies L-amino acids as Generally Recognized As Safe (GRAS) for direct food additives. Arginine Aspartate itself is 'Not Classified' by ECHA GHS, indicating a high safety profile.
