An injectable ice “slurry” may selectively decrease unwanted fat and has the potential to become one of the most performed cosmetic procedures in plastic surgery practice. The ice slurry comprises a sterile solution of normal saline and glycerol plus approximately 20 percent to 40 percent small ice particles. It can be inserted straight into fat deposits via a hypodermic needle, causing the adipocytes to crystallize and disappear.  The fat is reduced gradually as it is with other fat-reduction procedures and technologies. However, researchers believe further studies in humans are required before any firm conclusion can be drawn about ice slurries and fat reduction.
