Super-Cooled Injections Might Ice Away 'Deep Fat'

WEDNESDAY, Jan. 22, 2020 -- The Harvard-associated lab that created the "CoolSculpting" process of reducing fat says it's on the trail of the next advance in nonsurgical slimming.

CoolSculpting freezes fat cells by applying an ice-cold gel pad to the skin, causing cells to die off and either be flushed away or absorbed by the body, said lead researcher Dr. Lilit Garibyan, an investigator at the Wellman Center for Photomedicine at Massachusetts General Hospital in Boston.
