What makes your body grow scar tissue instead of skin?

Question

Is it always scar tissue and it just blends in better or does the body sometimes grow skin?

In: Biology

Answer 1

Human skin has layers. When the bottom most layer (the basal cell layer) is damaged, scar tissue forms. The basal layer produces new skin cells. If that layer is damaged, that area can no longer produce skin cells, so scar tissue fills in the gap. More superficial wounds that don’t damage the basal layer are less likely to scar.
