Manganese PCA

What is Manganese PCA?

Manganese PCA, or manganese pyrrolidone carboxylate, combines the essential trace mineral manganese with pyrrolidone carboxylic acid (PCA), a component of the skin's natural moisturizing factor derived from glutamic acid. This soluble salt serves as a humectant in skincare formulations like moisturizers, toners, and conditioners. It works by drawing atmospheric moisture into the stratum corneum, promoting water retention and preventing dehydration. Unlike occlusives, it provides lightweight hydration without residue. The chelated structure ensures stability and bioavailability, aiding skin conditioning by maintaining flexibility and smoothness. Commonly incorporated at low levels, it integrates seamlessly into water-based products, contributing to overall comfort and plumpness across various skin types.
