It was fine..! It was my first filler, so after comparing domestic and imported options, I decided on the imported one and went. I think the reason the under-eye area can look spread out is usually because low-cost domestic filler makes it happen... Naturalness was the most important thing, so I think they paid careful attention to that part, and the duration is pretty decent too. But the aegyo-sal looked a little grainy for a while, which I noticed, but after a lot of time passed it got better again. What I was a bit sorry about was that when they injected the aegyo-sal filler, they inserted one side from the outer corner of the eye so it looked natural, but the other side wasn't done that way, so the needle mark showed. Also, if your eyes are naturally uneven like mine, a retouch visit is absolutely necessary.
There was a slight lingering disappointment, but they worked hard on molding and carefully shaping it as they injected, so I liked that part.
