Zincidone® is 
a 100% natural origin biomineral complex composed of zinc, a trace element essential to our body, and L-Pyrrolidone Carboxylic Acid or L-PCA, a physiological molecule of the skin. The L-PCA is obtained by cyclization of L-glutamic acid, an amino acid of plant origin.

Zincidone® is the zinc salt of pyrrolidone carboxylic acid, a dual-active complex that provides the skin and hair with the beneficial effects of zinc and L-PCA:

1. Zinc is involved in the synthesis of nucleic acids, including DNA, but also in protein synthesis, cell division, and in the structure and co-enzymatic activation of many key molecules in the organism and in the skin. It plays a role that is just as important in cell differentiation and thus has considerable healing activity. It also prevents the development of microbial infections as a result of its remarkable antiseptic propertiesConsiderable scientific research has shown that zinc reduces sebum secretion by inhibiting 5 α-reductase. It has also been shown that the cutaneous application of preparations containing zinc increases zinc levels in the epidermis.

2. L-PCA can bind an active molecule and becomes its vehicle. Several studies have shown the significant improvement in the bioavailability of a cation bound to L-PCA in comparison to its classical salt.
