WHY SCARS ARE SO DIFFERENT FROM NORMAL SKIN There are two main layers of skin - the epidermis (superficial) and the dermis (deep). The epidermis is responsible for constant tissue renewal. So, when skin damage is limited to this layer, the wound heals without a trace.

But when the dermis or deep layer is affected, a scar is almost guaranteed. A scar looks so different from normal skin, because the basal layer of the epidermis responsible for its repair is damaged - the skin cannot be the same.

And the body decides to fill the "gap" with connective tissue, which does not have a complex structure like skin.
