Sodium PCA is the sodium salt of pyrrolidone carboxylic acid, as a natural amino acid derivative. It is a natural hydrating agent acquired from oil, plants, and fruits. Furthermore, it acts as a humectant that traps water and increases the water content in the top layer of the skin, giving the skin a moisturized effect.

As mentioned, Sodium PCA acts as a humectant, which means this compound traps water and keeps the skin moisturized. Due to its ability to absorb water from the environment, it reduces the appearance of wrinkles, thus making it an anti-aging agent. Moreover, it has anti-inflammatory and non-irritating properties, which makes it safer for all skin types.
