Just like liposuction, Cryolipolysis or Coolsculpting is a non-surgical method for reducing fat cells in a treated area. It is considered the world's number one clinical fat freezing device and is often seen as the best alternative to liposuction. Cryolipolysis works by freezing fat cells, causing them to die and eventually be eliminated naturally from the body via the lymphatic system. The treatment can have dramatic results, and it usually takes 4 to 12 weeks for the body to eliminate the fat cells.
