Why does it take 4-8 weeks for the results from cool sculpting to be noticed? What is happening internally until then?

As others have mentioned, the fat cells are crystallized, die, are absorbed and eliminated by the body over time. This process results in a gradual improvement in appearance without others immediately noticing you've had "work done." I can't speak for all, but in my practice, patients have noticed clothing fitting looser in the first 3 weeks. As they improve and feel better over the next 2-3 months, they have been inspired to treat other areas. Studies have found no harm to liver or cholesterol levels, so numerous areas can safely be treated.

It takes a few weeks to months to see results because the body has to clear the damaged fat cells through the lymphatics and the inflammation has to go down after treatment.  Best, Dr. Emer.

Thank you for your question. It takes a few weeks for the fat cells to die and be removed from our lymphatic system. If you would like more information, please ensure that you see a board certified plastic surgeon. Regards,
