The gel permanently stays within the place of its injection. It is surrounded by a thin connective capsule consisting of 1-2 layers of the cells like fibrocytes and connective fibers. This capsule assures that the gel does not spread through the intratissue fissures, nor into the blood vessels lumina, which excludes contamination of the blood and lymph vessels with the gel particles that would lead to their occlusion. Also, macro and microscopic examination does not reveal any signs of calcinosis within the sites of the gel injection.
