What is Sodium PCA?
Sodium PCA is a naturally occurring humectant derived from the amino acid proline. It is commonly found in human skin as part of the natural moisturizing factor, and it can be synthetically produced for use in skincare and cosmetic products.
Its primary function is to attract moisture to the skin, which can help maintain skin hydration and smoothness. Research indicates that it is generally well-tolerated by most individuals and is considered safe for topical use. However, some individuals with highly sensitive skin may experience irritation.
When you see Sodium PCA on a label, it typically indicates the product is designed to enhance skin hydration and moisture retention. It is considered a beneficial ingredient in skincare due to its ability to draw moisture without making the skin feel greasy.
