I got forehead filler, and I started experiencing side effects about 6 months or a year later. I think it was around the time I
started experiencing the side effects when I was really stressed and my immune system was really weak. At that time, my forehead felt really heavy, as if blood was rushing to it, and the area where I got the filler swelled up a lot. Is it that domestic filler doesn't work for me? If I get a foreign product, will I not experience these side effects?
