Coolsculpting by Zeltig or "fat freezing" is a new technology to treat unwanted localized fat deposits. Developed by Harvard doctors, it is FDA approved for fat removal. The amount of fat removed varies, but the minimum amount is 20%. It is best utilized in patients that are at or near their ideal body weight. It works by freezing fat cells that are then eliminated from the body by cryolipolysis. It takes 8-12 weeks to see the results as the frozen fat cells are slowly removed by the body. The areas of the body that can be treated are: abdomen, flanks, bra line, inner thighs, upper arms, men's breasts and some outer thighs. The company is new and is working on developing head pieces to treat other areas of the body.
Coolsculpting works by applying a mechanical head over the targeted area which "sucks" the tissue into the headpiece that has cooling panels. Over the course of one hour the cooling panels freeze the tissue, the skin is protected from frostbite with a protective gel pad, the fat cells form ice crystals within the cell that cause them to die. The body then "cleans up" the dead fat cells over the next 2 months. The treatment is performed as an outpatient, no anesthesia, no IV's, no Propofol (Michael Jackson's drug of choice), and no down time.
It is a wonderful adjunct to body contouring. It can be used instead of surgery and also after surgery (liposuction, tummy tucks) to improve the results. It can be performed again and again, even in the same areas. The price is less than surgery and anyone can undergo a session, even with medical conditions that prohibit them from having a surgical procedure. The difference between freezing fat and radio waves is that Zeltig permanently removes the fat cells, the radio waves just shrink fat cells. We are born with a certain number of fat cells in our body, when they are removed, they are gone forever! Shrunken fat cells can become larger again, they have not been removed.
I hope this helps explain CoolSculpting.
