Sodium PCA is the sodium salt of pyroglutamic acid (PCA). It is a naturally occurring component that is present in the human body. Moreover, it makes up about 12% of the skin’s natural moisturizing factor (NMF) that contributes towards keeping the epidermis healthy. Sodium PCA is classified as hygroscopic, which means it attracts moisture from the air.
Sodium PCA is naturally derived from fruits, coconut oil, and soybean. It can also be produced in synthetic settings. It is added to a wide of range skincare products.
The main benefit of the active ingredient of sodium PCA is hydration. However, this active ingredient has additional beneficial properties that will be discussed further.
The active ingredient of Sodium PCA acts as a humectant that “traps water” in the skin. Similarly to hyaluronic acid, it draws moisture from the surrounding air which helps to increase the water content in the skin’s top layers.
Sodium PCA also helps to reduce wrinkles. Due to its ability to increase water content in the skin, it helps the skin to achieve a more youthful look.
Moreover, the active ingredient of Sodium PCA contributes to restoring the skin’s barrier. In return, this facilitates the skin’s ability to “trap” appropriate amounts of water in the skin.
The active ingredient of Sodium PCA does not have major side effects and is safe to use on daily basis, even multiple times per day. Individuals with allergies to the active ingredient itself, coconut oil, and/or soybean should avoid using products that contain Sodium PCA.
Individuals with dry skin would highly benefit from skincare products that contain Sodium PCA in their formulations due to their moisture-attracting properties.
