Sodium PCA

Also known as: Sodium Pyrrolidone Carboxylate

Sodium PCA is a naturally occurring component of human skin, part of the Natural Moisturizing Factor (NMF). It is a powerful humectant, meaning it attracts and holds water from the air, helping to keep the skin hydrated. It plays a crucial role in maintaining skin barrier function and overall skin health.
