Calcium PCA
What is Calcium PCA?
Calcium PCA is the calcium salt of pyrrolidone carboxylic acid (PCA), a cyclic derivative of the amino acid glutamic acid present in the skin's natural moisturizing factor. This water-soluble ingredient mimics components naturally found in the skin's uppermost layer, aiding in moisture retention. In cosmetic products like moisturizers, serums, creams, and cleansers, it functions by attracting and binding atmospheric water to the skin surface while supporting the skin's barrier against dehydration. As a skin conditioning agent, it helps maintain suppleness, reducing the appearance of dryness and flakiness. Its lightweight, non-oily profile makes it ideal for daily use across various formulations, contributing to a smoother skin texture without residue.
