Fat cryopreservation was introduced from America. Now the most popular fat technology is to detect the fat after liposuction. The optimized fat was preserved in liquid nitrogen at-180℃ by using American patent cryopreservation solution, and the high activity of fat cells could be maintained for 20 years.

Our common refrigerator can't freeze fat, because the ice crystals produced during freezing will puncture fat cells and lead to their death.

Frozen fat can be used for fat transplantation without frequent liposuction. Most importantly, fat contains a large number of adipose stem cells, which can be used for the treatment of diseases.

So now more and more people are storing fat. Many medical and aesthetic institutions can deposit it.
