Moisturizer Ingredients In Skin Care Products: humectant

Sodium PCA (pyrrolidone carbonic acid)

NaPCA

NaPCA is one of the skin’s most important natural moisturizers — a humectant. Old skin, however, contains only about half the NaPCA as young skin. NaPCA can pull water into the skin from the air. NaPCA is a wonderful moisturizing agent. As children, our skin possessed an abundant supply of this remarkable moisturizing agent called NaPCA (sodium PCA). This substance, in addition to keeping skin soft and wrinkle-free, chemically attracts water from the surrounding air. As we age, sodium PCA levels drop by 50% or more.
