Caution
Sodium PCA is a moisturising ingredient that may be found in oils, plants, and fruits. It's pyrrolidone carboxylic acid (PCA), commonly known as pyroglutamic acid, in sodium salt form. It is also known as the amino acid proline, which is the building block of all proteins. The salt form of sodium PCA molecules makes it water soluble.
Sodium PCA is a humectant found in the skin naturally. It's also found in a number of skin and hair care products. Humectants help to keep moisture in your skin and keep it there. They collect water droplets from the air and seal them into your skin's outer layer, giving it a moisturised look.
