What changes can you expect from forehead augmentation surgery?

I am considering forehead augmentation surgery and am curious about the actual changes. I would like to know how the shape and height of the forehead feel after the surgery, as well as how people around me react to the changes. I would also appreciate it if you could share the level of pain and precautions I should take during the recovery process. Please provide feedback if you have any useful information regarding the expected effects of the surgery and how to manage the aftercare.
