I got my first nose filler at the age of 21 and also had it retouched at that time. After that, I did it three times in one year, and the first day was the prettiest. After that, it gradually faded away. However, when I first used domestic filler without knowing anything, it fell out really quickly, felt hard, and sometimes felt tight, but I didn't experience that at all when I used imported filler! And the filler piled up, creating a subtle bridge of the nose! Fortunately, it didn't spread, but it seemed like the filler had clumped up between my eyebrows. I wear my bangs down so it doesn't show off.
