5-year review of nose and forehead filler

About 5 years ago, I received filler between the eyebrows for the first time and was very satisfied. I had a bridge of the nose, but really only had no eyebrows. After getting filler for the first time, I was so satisfied that I was told by the hospital to have it retouched every 3-6 months, and I think I had it done about 4 times. (They said I had to melt it and retouch it once, so I melted it and got it again the third time.) After the last filler treatment, I thought it was a hassle and didn't really need to be retouched, so I didn't go to the hospital. It's been three years, but I still have the filler left. There's enough left that it doesn't need any retouching (about 80%?) and the filler seems to be spreading a bit (5-10%), but I'm not concerned. I have no intention of getting retouched in the future, and even if the filler does not dissolve and continues to be used, I have no intention of dissolving it unless inflammation or other problems occur. I am satisfied. I received the procedure at a clinic in Gangnam.
