I will tell you a review of the HIKO procedure. I highly recommend it to people who do not want to have surgery but want to make a change! But... I decided to get nose surgery after all, so I'm looking into it haha... Still, it worked well for a procedure. My nose was flat and similar to a box nose, but after having a nose job, I got a bridge of the nose...! It's just that my big nose doesn't work... The maintenance period is 1 and a half years! I think it was about the same. The diagonal profile is really lifelike bb, so the angle is the same when I take four pictures of my life or take a selfie. I had HICO twice, but everyone said they would change to nose surgery after 2-3 times, and I think that's true.. I don't want to have surgery and change. If there is someone you want to give to, do it! I highly recommend it!
