Among the comments here, there was a post saying just do it where you do it a lot, but I regret not following it..
Hair loss from the incision area (where there was a lot of bleeding right after the surgery), forehead wrinkles, forehead wrinkles, and I don't know about the lifting effect.. Scars and everything that was promised didn't work out. There is no negotiation during the consultation for revision surgery.
If I were to have surgery again, I would go to a famous place that advertises that it will definitely cut out the wrinkles between the eyebrows and the corrugator muscle.
Also, there is an option to reduce the forehead through an incision instead of an endoscope. This method will be more effective as the corrugator muscles will be more precisely organized, the wide forehead will be reduced, and the skin itself will be reduced.
