It’s been 5 years since I had breast fat transplant.
Since there was no fat, I only did the first round.
As long as it's not excessive and the left and right breasts are symmetrical and have a natural volume, I'm satisfied with just the first round and it's maintained about 70% well so far.
However, thighs that have had fat removed may have lumps of cellulite or may not be smooth, so more care is needed over time.
