"The key to successful fat grafting lies in the technique." Dr. S.Coleman
"The grafted fat must gain its own blood supply in its new location in order to persist long-term (neovascularization), and this generally is not possible when large amounts are injected at once and when specialized instrumentation and techniques are not employed." Dr. M. Law
The challenge of homogenous extrusion
Injection performed with Lipopen
"The degree of shear stress, which is a function of flow rate, did significantly affect fat graft viability. Fat grafts injected slowly with low shear stress significantly outperformed fat injected with high shear stress, suggesting that shear stress is a more important variable regarding fat graft viability than pressure."

Here the same syringes of fat injected in continuous mode, manually and with Lipopen.
