What Are Scars?
When you get an injury to the skin, whether accidentally or as part of a surgery or procedure, the body repairs the skin with collagen, the same fibrous protein that makes up the tissue it replaces. The difference is that while regular skin is made up of collagen fibers linked in a random basket weave formation, in scar tissue the collagen cross-links and forms a pronounced alignment in a single direction, making it more visible compared to normal skin.
