Fat injections also referred to as facial fat grafting or lipofilling is a facial rejuvenation procedure which creates volume to key areas of the face to restore a more youthful and fuller appearance. Targeted fat injections can also add volume to fill in fine wrinkles and deeper lines, skin hollows. Fat injections can also be used for scar revision.

The principle of the procedure involves the harvest of fat from another area of the body, often the inner thighs or knees followed by fat purification and then finally re-injection into the planned areas of the face. Although fat injections can be performed on its own, it is more commonly combined with facial rejuvenation procedures such as blepharoplasty, facelift, brow lift or laser resurfacing. The procedure adds facial volume by acting as a scaffold for the skin, recreating a vibrant and youthful appearance.
