Variants of Fat Grafting: From Structural Fat Grafting to Microfat, Sharp-Needle Intradermal Fat (SNIF), Nanofat, Emulsion, SNIE, FAMI, and SEEFI

The use of facial fat grafting has traditionally been limited to increasing the volume in the subcutaneous plane. Fat grafts have only rarely been applied in more superficial dermal planes or in deeper planes.
