Micro Fat Grafting vs Fillers for Under-Eyes: Why Autologous Fat Wins
Medically reviewed by Dr. Lee Young-geun, board-certified plastic surgeon · Last reviewed:
Synthetic hyaluronic acid under thin lower eyelid skin frequently yields blue Tyndall shadows and lumpiness. Purified autologous micro-droplets provide permanent, biocompatible smoothness.

The thin skin problem
The skin of the lower eyelid is the thinnest on the human body — roughly 0.5 mm thick. When synthetic hyaluronic acid fillers are injected here, even minor surface irregularities cause visible bumps or light refraction that looks like a bluish bruise (the Tyndall effect).
Furthermore, hydrophilic fillers absorb water unpredictably, often causing puffy, unnatural bags months after injection.
The micro-fat grafting advantage
Autologous micro fat grafting harvest a minute volume of your own adipose tissue (usually from the inner thigh or abdomen), purifies it into micro-droplets, and places it into deep supra-periosteal layers with multi-tunnel blunt cannulas.
Because living cells integrate directly with local tissue, the contour is soft, seamless, and permanent once grafted.
Combining with fat repositioning
For severe tear trough deformities extending into the mid-cheek groove (indian band), Dr. Lee combines orbital fat repositioning with micro fat grafting for total mid-face rejuvenation.
