3 years after fat graft to the forehead and temples - can lumps and dents be corrected? (photo)

Facial fat transfer is inherently unpredictable, and precise and can be unforgiving.
Removing that from undesirable outcomes can be difficult and sometimes borderers on impossible.

Your situation is too complex to make an assessment and give you accurate recommendations based on photos of laundry. I suggest your schedule multiple in person consultations with local board-certified plastic surgeons who have a lot of experience with facial fat transfer.
I generally do not recommend having virtual consultations and I definitely do not recommend traveling long distances for elective surgical procedures.
The Importance of properly vetting plastic surgeons by having multiple in person consultations and having the ability to do in person follow up is very important.
The temple region has virtually no host tissue to support grafted fat unless the fat is placed into the temporalis muscle.
I generally recommended patients stay with fillers because they are so much superior to grafting fat. Obviously longevity is the one thing lacking with fillers but generally speaking fillers are highly precise, predictable and very forgiving if you don’t like the results. Grafting fat is the opposite.
Look for local board-certified plastic surgeons in your community who seem to have a lot of experience with facial fat transfer and get an in person consultation. For second opinion consultations it’s generally a good idea to come prepared bringing with you proper before and after pictures and if possible a copy of your operative report. Those should be available from the surgeon who did your procedure though your operative report is most likely written in Korean.
