For many years embalmers have injected many different substances using hypodermic needles underneath the cadaver's skin to fill out emaciated tissues and wrinkles for recreating lifelike contours. Hizone's Tissue Filler has been the original successful product developed which forms a non-shrinking moldable gel after reacting with the water content within the cadaver's tissues. It will not be absorbed by the tissues over a period of time and disappear. Our product formulation allows you to shape the resulting gel shortly after injection and that gel will form a non-flowing solid that has similar texture and feel as embalmed tissues. The Tissue Filler may be thinned to a more easily flowing liquid by using a small quantity of Tissue Filler Solvent. The hypodermic syringe and needles should be cleaned using Tissue Filler Solvent both before and after injecting Tissue Filler.
