Injuries happen everyday, even the smallest ones. But injuries such as cuts from knifes etc on fingers, hands etc, they sometimes leave a scar on the skin's surface, "cause their deep". How does this happen?? Why does the injury leave a scar??
How does a cut/injury be
deep enough to leave a
scar on the skin and
why?
It's not about depth, more about width, cleanness, and alignment of the edges. If you use a scalpel or a saw, you get different scars. Also if the tissue amount lost is big, you have to get it stitched in order to get a nice scar afterwards. All wounds heal with scars, sometimes they're so minor and thin you hardly see them - called primary healing. If the wound had not been attended to, infected, too wide, etc. - large scar later: secondary healing.
