Sodium PCA is a skin-identical humectant—the salt form of pyrrolidone carboxylic acid—found in your skin’s Natural Moisturizing Factor. It attracts and binds water to help maintain moisture balance, keeping skin soft, comfortable, and bouncily hydrated without heaviness. Gentle and lightweight, it suits all skin types—especially dehydrated, oily, or sensitive—and layers beautifully with other hydrators.
