Health Blurb; Why do we get scars?

The famous boy-wizard Harry Potter has his iconic lightning-bolt scar, inflicted by a Dark Wizard when he was a baby. However, it doesn’t take a spell to cause scars to form on your body. Scars are created when your skin gets torn, be it by a knife or a stray piece of sharp wood. However, unlike paper cuts and shallow skin injuries, the deeper layers of skin beneath the dead skin cells – the dermis – are damaged.
After the injury heals, the scar leaves behind a trace of what the wound was; how bad the trace is depends on how bad the injury was. Scars are generally flat and paler than the skin surrounding them. Why do scars look like this, and why do they form in the first place? When the dermis is torn, the body has to create new fibers of the protein collagen (the same stuff that forms your lips) to fix the damage. However, since the human body can’t repair the damage so it looks like it did beforehand, the scar appears as a result.
There are ways to remove scars partially (there is yet to be a way to remove them all the way), steroids, needling, and surgery being a few of them. However, these should not be done without consultation with a doctor.
