It is a fancy way for someone to promote their fat injection practice. Fat injection to the face is done in small parcels. You can call it what you want but it is the same.
Great Question. During fat transfer, the fat can be processed so that it's consistency, thickness,etc can be modified so that it's best for the area being treated.Harvested fat is lumpy. Controlled filtration (think strainers) bring the size down to milli, micro, and nano sized particles and make the fat consistent so the placement can do what you want it to do.Nano fat is sized so that it can be used intra-dermally and in the lower lid so it great for texture and color issues with facial skin.
