Science
Mechanism of Action
This ingredient delivers a precise combination of potassium and magnesium ions, key electrolytes, alongside aspartic acid. Magnesium aspartate actively supports the structural integrity of proteins in the skin's outer layers, optimizing hydration and promoting a softer, smoother epidermal surface. Magnesium further contributes to restoring the skin barrier, mitigating inflammation, and maintaining optimal skin pH. Aspartic acid serves as a molecular carrier, facilitating the entry of these crucial ions into skin cells, thereby supporting cellular metabolic functions.

Stability
Optimal stability is observed between pH 6.0 and 8.0, with a particularly stable range of pH 7.0-8.0 at room temperature (20-25°C). Magnesium aspartate, a component, is hygroscopic and may require specific formulation considerations to maintain stability.
Safety
Safety Profile
The CIR Expert Panel affirms that alpha-amino acids, including the components of Potassium Magnesium Aspartate, are safe for use in cosmetic and personal care products, provided they are formulated to be non-irritating and non-sensitizing. Cosmetic concentrations are generally low, limiting systemic exposure. No specific maximum topical concentration was identified, although concentrations up to 0.3% were noted for related amino acids in aerosolized products.
