Science
Mechanism of Action
This ingredient works by boosting skin conditioning, leading to increased smoothness and a reduction in flakiness and roughness. It provides bioavailable magnesium to improve barrier function and possesses light humectant properties from its gluconic acid salt, aiding in skin hydration. Magnesium salts are broadly known to enhance dermal permeability and support epidermal regeneration. When combined with minerals like Zinc and Copper, Magnesium Gluconate can act as a radical scavenger, protecting cells and increasing cellular oxygenation and metabolism.

Formulation
Stability
Magnesium Gluconate is highly soluble in water, with slight solubility in ethanol and very minimal in methylene chloride. It is generally stable under typical storage conditions when shielded from moisture, light, and heat, but may degrade upon exposure to high temperatures or acidic environments. Its hygroscopic nature necessitates dry storage to prevent clumping.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not formally assessed Magnesium Gluconate; however, its gluconic acid component has been reviewed and deemed safe. The FDA lists Magnesium Gluconate as Generally Recognized As Safe (GRAS) for direct food use without specific limitations beyond good manufacturing practices. EWG indicates low concerns across categories including cancer, allergies & immunotoxicity, and developmental/reproductive toxicity.
