Dear Confused:
Good Question! The top layer of your skin is called the epidermis and that's the layer that is
always renewing and replacing itself. Generally, when you have a small scrape or cut, your skin
forms a bandage called a scab while special skin cells underneath repair the scrape. Then the scab
falls off and you have new unscarred skin underneath.
But sometimes the damage is a little greater. If you are missing too much skin tissue, you
don't get good-as-new looking skin, you get scar tissue made from a different kind of skin cell.
This kind of skin cell makes an all-purpose kind of repair out of skin that is thick, tough and
somewhat rough. Even when the top layer of the scar tissue is sloughed off, there is more scar
tissue underneath!
Signed,
Wendell
