[Filer] Forehead filler

I got filler on my forehead and didn't get any molding done, but it protruded out unnaturally and was bumpy for a few days, which was a hassle. Maybe it was because of the swelling, but my eyes were also swollen, so I was scared to go out... I was scared of what I would do if my forehead hardened like this. Celebrities have their foreheads raised from above. The treatment was done naturally in a round shape, but I'm curious as to what type of treatment is used. My forehead only had lumps above my eyebrows.
