Sodium PCA, or sodium salt of pyrrolidone carboxylic acid, is a naturally occurring component of the skin's Natural Moisturizing Factor (NMF). It is a humectant, meaning it attracts and binds water. In skincare formulations, sodium PCA is primarily used for its moisturizing properties. It helps to increase skin hydration by drawing moisture from the environment into the skin and preventing transepidermal water loss.

This ingredient is known to be a good skin conditioner and can help improve the feel and appearance of the skin, making it appear softer and smoother. It is generally considered a safe and non-irritating ingredient, suitable for most skin types, including sensitive skin. Its inclusion in cosmetic products is often to enhance the overall moisturizing efficacy of the formulation. Sodium PCA is biodegradable and has a low environmental impact. It is commonly found in moisturizers, serums, cleansers, and hair care products. Its presence in the skin's NMF underscores its role in maintaining skin barrier function and hydration balance.
