What Is Sodium Ascorbate?
Sodium Ascorbate is the sodium salt of ascorbic acid, offering a more pH-neutral alternative to pure Vitamin C. This buffered form maintains many of the antioxidant and brightening properties of ascorbic acid while being significantly gentler on the skin.
As a water-soluble compound, Sodium Ascorbate penetrates effectively and provides protection against oxidative stress. Its neutral pH makes it suitable for those who experience irritation from acidic Vitamin C formulations.
