Sodium PCA

Sodium PCA (Pyrrolidone Carboxylic Acid) is a sodium salt of pyrrolidone carboxylic acid, which is a natural component of the skin's natural moisturizing factor (NMF). NMF is a mixture of compounds that help to maintain the hydration and integrity of the skin.

Sodium PCA is a humectant, meaning it has the ability to attract and bind moisture to the skin. It is commonly used in skincare products, including serums, moisturizers, and cleansers, for its moisturizing properties.

By attracting water molecules from the environment and binding them to the skin, sodium PCA helps to hydrate and improve the skin's moisture levels. It can also help to improve the elasticity and smoothness of the skin, leaving it feeling soft and supple.

Additionally, sodium PCA is believed to have some antioxidant properties and can help to protect the skin from environmental damage.

Overall, sodium PCA is a beneficial ingredient in skincare products, particularly those aimed at improving hydration and maintaining the skin's moisture balance.
