About 10 years ago, regular nose fillers disappeared quickly, so I was looking for semi-permanent fillers and went to the most famous plastic surgery clinic in Busan at the time. During the consultation, they recommended a semi-permanent filler called Perform, saying that it was a cost-effective filler. They said that it was a filler that lasted more than 5 years, and when I first got it and got a retouch a few days later, my nose seemed to have become neater and higher, so I was satisfied. However, after about 1-2 years, it got a little lower. Still, I got by without any major discomfort. After 5 years, my nose was almost completely gone, but the problem was that I could feel the bud between my eyebrows. Semi-permanent fillers never go away. It's been 10 years, but I can still feel the filler in my nose. There are no particular side effects except for the occasional big pimple on my nose, but I'm worried about whether I should get it removed. Those who are thinking about semi-permanent should know that it will never go away.
