Scar Formation

Scar Formation: Scars occur as a natural part of the healing process. Every wound, except for very minor lesions, would incur some scarring.

Scars are formed by fibrous tissues that replace normal skin after surgery, acne or injury. The same collagen fibers that comprise normal tissue are present in scars.
A Scar occurs when collagen fibers align in a single direction rather than the random formation found in normal tissue and when the body produces too much collagen.

Types of Scars: Most injuries or surgeries heal with flat, pale scars. When the healing body produces excess collagen the result can be raised hypertrophic or keloid scars.

A scar is said to be hypertrophic when it is raised above the original skin. Hypertrophic scars are typically a raised red lump on the skin.
A Keloid is a hypertrophic scar that has grown beyond the original wound area. Over time, a keloid scar may grow enough to hamper movement.
Hypertrophic and keloid scars occur most commonly in young and dark skin
