Science
Mechanism of Action
Sodium Erythorbate functions as a powerful antioxidant by readily reacting with atmospheric oxygen and other oxidizing agents in aqueous solutions. This action protects other delicate ingredients within a formulation, preserving its color, scent, and therapeutic efficacy. When applied to the skin, its antioxidant properties enable it to mitigate UV-induced damage, contribute to a more uniform skin tone, stimulate the production of collagen, and assist in repairing visible signs of aging.

No data available to suggest this ingredient is commonly 'dusted' or used at sub-efficacious concentrations for cost-saving measures.
The Formula
Formulation
Stability
While stable in its dry, crystalline form, Sodium Erythorbate becomes reactive as an antioxidant in water solutions. For optimal stability, products containing this ingredient should be housed in light-resistant, tightly sealed containers and stored in cool, dry, and well-ventilated conditions to prevent degradation from light exposure and atmospheric oxygen.
