Why This Ingredient Matters
Sodium PCA is a powerful humectant and a component of the skin’s Natural Moisturizing Factor: the mixture of water-binding substances that helps the outermost layers of skin maintain hydration. It attracts and holds moisture, helping skin remain soft, smooth, and supple.
Why Formulation Matters
Healthy hydration depends on a network of moisture-binding substances rather than any single ingredient.
Luzern combines Sodium PCA with complementary humectants such as Glycerin and Hyaluronic Acid, along with emollients and lipids where appropriate, to support hydration through multiple mechanisms.
