Scar tissue replaces normal skin tissue after the skin is damaged. Though
scar tissue is made up of the same substance as undamaged skin, it looks different because of the way the fibers in the tissue are arranged. Scars form every time the skin is damaged beyond its first layer, whether that damage comes from a cut, burn, or a skin condition like acne or a
fungal infection. Though there are ways to minimize the appearance of scars, there is no way to remove them entirely. Usually originates from deep punctures or cuts that are not properly stitched.
Also a
RHCP song, but the word origin has been around way before the song came out.
