If possible, do not backslide

They say they are good at back and bottom canthopuses, so I got them together when I had double eyelid surgery. It's a famous hospital for quick cheekbones and nose surgery, but in the end, the back canthoplasty was ruined~ It's covered with eyelashes, so it's not noticeable unless you look through it. I told the hospital where I had the surgery that the back canthoplasty was wrong, but they told me that I had the corners of my eyes that originally looked like that, so I should just stay with it. Is there anyone who has U-shaped eyebrows without surgery? It's not too bad, and I'm not very sensitive to that part, so I live, but I think it's better not to have an open back if possible. I'm thinking of getting it rebuilt someday, but if you're sensitive to scars, I think you'll regret it greatly.
