Spherulites are microspheres which are composed of multiple concentric layers. These layers contain specific ingredients depending on the product, which are then released gradually over time as the layers break down. This provides a long acting effect on both the skin and hair surface. There are two types of spherulite in the Virbac products, non-ionic and cationic. The non-ionic spherulites penetrate into  the skin, and the cationic spherulites bind to the skin and hair surface, providing their beneficial effects  
at both of these sites.
