Under-Eye Filler vs Fat Grafting for Aegyo Sal: Which Lasts Longer and Looks More Natural?

8 min readBy MyDoc KoreaReviewed by the MyDoc Korea medical coordination team

If you have decided you want aegyo sal, the next question is how to create it. The two most popular methods, dermal filler and fat grafting, each have distinct advantages. This guide will help you make the right choice based on your priorities.

The Fundamental Difference

Filler uses hyaluronic acid (a gel-like substance) injected with a fine needle. It is quick, reversible, and needs little downtime for most people. Fat grafting harvests your own fat cells, purifies them, and transfers them to the under-eye area. It is a minor surgical procedure but produces more natural, longer-lasting results.

Detailed Comparison

Factor Hyaluronic Acid Filler Fat Grafting
Longevity 6-12 months 3-5+ years (surviving fat is long-lasting but changes with weight and aging)
Natural Look Good initially; may appear puffy if overfilled Can look very natural when the fat survives evenly
Natural Feel Soft but slightly firmer than natural tissue Identical to natural tissue (it IS your tissue)
Cost Per Session $300 - $600 $800 - $2,000
Long-Term Cost $600 - $1,200/year (repeat treatments) $800 - $2,000 (one-time, possible touch-up)
Risks Tyndall effect (bluish tint), migration, lumpiness Asymmetric absorption, overcorrection
Reversibility Fully reversible with hyaluronidase enzyme Partially reversible (excess can be dissolved/removed)
Downtime None to minimal 3-5 days of swelling

The Tyndall Effect Warning

One risk specific to under-eye filler is the Tyndall effect, where filler placed too superficially creates a bluish discoloration visible through thin under-eye skin. This is why it is critical to choose an experienced injector. An experienced injector placing filler at the proper depth can reduce, but not eliminate, this risk.

Who Should Choose Filler?

  • First-timers who want to test the aegyo sal look before committing
  • Medical tourists with limited time in Seoul (little downtime)
  • Patients who prefer a reversible option
  • Budget-conscious patients (lower upfront cost)

Who Should Choose Fat Grafting?

  • Patients who want the most natural-looking, long-lasting result
  • Those tired of repeat filler appointments
  • Patients who want to combine with other eye procedures
  • Those who prefer using their own tissue over synthetic materials

Combining with Other Procedures

Both filler and fat grafting for aegyo sal can be combined with double eyelid surgery, ptosis correction, or under-eye dark circle treatment for a comprehensive eye rejuvenation.
