I got forehead filler from the director of Seomyeon Mo Clinic almost 8 years ago. At that time, through a referral, the director said he was good at fillers, so I received a consultation in person and got the injection. It's been a while, so I don't remember the dosage. The capacity was quite large and they retouched it to give it a good shape. But maybe the filler wasn’t fully absorbed? My forehead is still smooth It's not as convex as it was before, but the sunken forehead has disappeared.
