Calcidone® is the calcium salt of L-pyrrolidone carboxylic acid (L-PCA). It is obtained by the cyclization of L-glutamic acid, an amino acid of plant origin. This product is a combination of calcium and L-PCA, which helps the skin to carry out or regain its role as a barrier by stimulating the cell differentiation process and activating the synthesis of total epidermal lipids, notably ceramides. Calcidone® also has strong anti-MMP1 activity, which helps to preserve the skin's integrity.
