I saw a really big effect from the first round. My face is the type that has a lot of fat. At first, I thought there was no effect and felt frustrated, but around 3 weeks later, it became very noticeable. It reduced so much that I was amazed, so I had really high expectations for the retouch, but.... They injected only a very small amount. So I kept asking how many cc they were injecting and why they were injecting less than before, but they only said that for a retouch, they look at the face and inject the appropriate amount accordingly....
So naturally, my satisfaction with the retouch was very low, and the effect was minimal....
It does seem like an injection that does not cause much swelling, but still, a solution is being injected, so for the retouch, it felt like even the time that solution stayed inside was a waste.... A pointless waste of time... I was so disappointed...
