Calcium Pca

What Calcium Pca is & what it does

Calcium PCA is the calcium salt of pyrrolidone carboxylic acid (PCA), a humectant that occurs naturally in skin as part of its moisturizing factor. In formulas it attracts and binds water to help keep skin hydrated and supple, while also supplying calcium. It is water-soluble and used at low levels in moisturizers and serums. As a skin-identical type of humectant, it is generally considered gentle and well tolerated.
