Continuity mistake: While Sean tries to prevent the jet from taking off, in the exterior long shots of the aircraft there are windshield wipers over two of the cockpit's windows, but in the exterior closeups such as when Castor brings Winters into the cockpit the wipers are gone. (00:06:35 - 00:10:20)
Continuity mistake: When Sean and Tito first drive the Hummer onto the runway, the jet is a mere short distance away, coming towards them. In the following shots, the distance between the Hummer and the jet has increased tremendously, for the ensuing drama to unfold. (00:09:40)
Continuity mistake: After Castor Troy is told they are being followed on the runway, there is a close-up of Sean Archer and Tito in the Hummer and the rear view mirror is gone. It is back in all the other shots. (00:10:00)
Visible crew/equipment: On the runway, two shots after Castor Troy says, "This is a big gun. Fly the f*ing plane," there is a side shot of the Hummer. As the camera pans in closer, the reflection of a crew member on the filming vehicle, which moves beside the Hummer, becomes visible at the Hummer's back end, just before it cuts away. (00:10:25)
Continuity mistake: When Castor Troy opens the jet door, the wall behind the cockpit differs when he pushes Agent Winters onto the runway, and the rest of the shots. (00:11:20)
Visible crew/equipment: When Archer gets into the chopper and takes off, next shot is of the chopper flying towards the camera and it is not Archer who is flying it - the chopper pilot wears head gear and a mic. (00:11:40)
Continuity mistake: After the jet crashes into the hangar, Sean Archer runs up the back end of a police cruiser, whose three blue flashing lights are completely shattered. In the next shot facing him, when he reaches the car's roof, two of the blue lights have repaired themselves. (00:13:45)
Visible crew/equipment: In the shoot 'em up scene at the hangar near the beginning of the film, right after Tito and Wanda take down Pollux, when Troy shoots an agent in the stomach and the agent flies back - you can see at least two cable wires pulling him backwards. You can first notice the 2 wires when the agent is running in slow motion right before he shoots him. (00:14:15)
Continuity mistake: At the airport hangar, after Castor reloads, in the close-up Sean is kneeling beside a crate with a large black/white SCI air freight sticker. In the overhead shot, when Castor Troy aims the gun at Sean, the sticker is gone. Debris also disappears. (00:15:35)
Continuity mistake: At the hangar, when Castor Troy is blown backwards in the turbo tunnel he hits the wire gate, and the metal bar, about 3-4 ft long, breaks off and begins to fall with him. Next shot, he lands on the floor, but the long bar does not. It just disappears. (00:17:45)
Continuity mistake: At the airport hangar, when Castor hits the wire gate in the turbo chamber, the top of his head is well below the metal bar. But, when the emergency shut-off is pressed, his unconscious body has sat itself up, because now the bar is at shoulder level. (00:17:50)
Visible crew/equipment: After Castor is captured at the airport hangar, when Sean pulls into his driveway the crew is reflected on the vehicle's surface. (00:18:15)
Continuity mistake: At the office, when Sean is given the bottle of wine for a job well done, the way the bottle is held, first by the assistant and then by Sean, differs between shots. (00:20:40)
Other mistake: On his own computer, Sean looks up his son's file, which states the boy died immediately and his date of death was September 9th, 1991. When Eve and Castor (as Sean Archer) are at the cemetery, the date of death on the headstone is September 24th, 1991. (00:21:15 - 01:14:50)
Continuity mistake: After Sean looks up his son's file on the computer, and types "case closed" on Castor's file, he rubs his head with his right hand in the close-up, but next shot he is rubbing his head with his left hand. (00:21:20)
Visible crew/equipment: When Sean first visits the Walsh Institute, he, Dr. Miller and Dr. Walsh walk in front of the circular glass window to view the ear reconstruction. In the next shot facing them, the reflection of a boom operator holding the boom pole is visible on the glass in front of Dr. Miller and Sean. (00:24:50)
Continuity mistake: At their home, when Sean tells Eve that he has one last assignment we see his scar. At the Walsh Institute, before the surgery, there is another close-up of the scar, but it differs from the previous shot. (00:30:20 - 00:33:05)
Visible crew/equipment: When Sean sees himself for the first time as Castor Troy, he takes the coat rack and slams it into the tri-fold mirror. The right side mirror is knocked back, and both the cameraman and camera are briefly visible in the reflection. (00:37:05)
Continuity mistake: After the surgery, when Sean (as Castor Troy) breaks the center mirror of the tri-fold mirror, what remains are the two side mirrors and white backing within the center frame. When Tito grabs him as he starts cursing, in these close-ups the reflections seen are as if all three sides are still intact. (00:37:15)
Factual error: The premise of the film is swapping the faces of the Hero and Villain. We can see the whole face of Sean Archer is intact in a water tank, which includes his eyelids and lips. When Castor Troy wakes up and confronts the doctor, despite his face being missing, he still retains eyelids and lips, which isn't possible as they would be missing. This should result in Castor having exposed eyes and teeth. (00:46:47 - 00:48:08)
Chosen answer: Surgical scar removal is a real thing, usually involving skin grafts or lasers. Keloid scarring is a result of the body aggressively attempting to heal/repair itself after trauma or injury (in this case, the gunshot). With proper surgical techniques, the body isn't traumatized to the point that deep scarring occurs. Of course, just like with the face surgery, the movie exaggerates the results of the scar removal.

I thought he kept it.
He says he wanted to keep it at the beginning of the movie, but when he is about to have his face changed back at the end of the movie, he says he doesn't need it anymore.
