Sodium Ascorbate
Sodium Ascorbate is the water-soluble sodium salt of vitamin C for use in aqueous formulations. It's used for antioxidant support and a brighter-looking complexion, though performance is generally weaker than pure ascorbic acid.

Our take
Is Sodium Ascorbate a Good Ingredient?
It lands at Fair because it does provide antioxidant support, but it oxidizes readily in water, which diminishes efficacy and can cause yellowing over time. Benefits are usually modest versus ascorbic acid, and mild irritation may occur in sensitive skin.
What it does
Skin Benefits
It offers antioxidant care that can reduce the look of dullness, though brightening effects are typically modest compared with pure ascorbic acid.
