The reason that scars never disappear... PM Date: 2/15/2007 2:45:14 PM ( 7y ago ) Hits:5668Size: 2047 char.
and are so darn diffcult to even reduce!
Have you ever wondered why scars persist on the skin even though the skin is by far the most regenerative organ that we have?
I have read some very interesting information lately on scarring. Contrary to popular belief on this site, scars are really not sites of incomplete healing or sites still in the process of healing. These areas of skin have healed. It's just that they have healed with scar tissue. Scar tissue is the glue that fixes the wounds.
A new generation of skin cells migrates from the basal cells (often called dermal stem cells) within the subcutaneous layer of tissue every 30-40 days. These cells will produce cells based upon the genetic information encoded within their cells that dictates the specific charachterics of each cell that slowly migrates to the epidermis (surface layer of skin). When tissue becomes scarred, the genetic information (DNA) within these basal cells actually becomes radically altered. In essence, the genetic formula for skin cells then becomes reprogrammed according to the scarred skin. The DNA of these basal cells now contains the information that instructs these cells to produce skin cells that are scarred. The scarring literally becomes locked within our DNA. It as if we were born with them.
This is why scars are perpetually on the skin even though the skin cells replace themselves every 20-40 days. Scars, as some would have you feel, are not areas of incomplete healing. These areas have healed and they have healed with scar tissue.
This is why scars are so difficult to change. You would have to figure out how to reprogram the DNA of these basal cells once again. Unfortunately, no one has been able to do this. Although scarring is easily programmed into the genetic information through the aquisition of a traumatic wound, it is impossible thus far to reprogram a lack of scarring.
Anybody who can figure out how will be the personal saviour of millions that suffer from scarring, especially facial scarring.
