Scar

A scar (cicatrix) is an area of ​​fibrous connective tissue that forms at the site of wound healing. Scars usually have a denser structure than the surrounding normal tissue from which they develop.

The formation of scar tissue is part of the normal healing process of damaged tissue in the body. When the skin or other tissues are damaged, a cascade of inflammation and regeneration reactions is triggered in response. As a result, a temporary matrix is ​​formed, consisting mainly of collagen. As healing proceeds, this matrix is ​​gradually replaced by normal tissue. However, in some cases, normal tissue is not completely restored and a scar of fibrous connective tissue is formed.

Scars can vary in appearance, shape and size depending on the type and depth of the injury. As a rule, over time, scars become less noticeable, change color and decrease in size. However, in some cases, rough, raised, or stretched scars may form, causing cosmetic and functional problems.
