Keloid and Hypertrophic Scar
What are Keloid Scars?
These are firm, smooth and dense spontaneous overgrowths of fibrous tissue that form on a healed wound. Keloid scars radiate from the original spot. They do not spontaneously subside and might arise even after excision.
Forming soon or long after a wound, keloids can get very uncomfortable and itchy and extend beyond the boundaries of the healed wound.
What are Hypertrophic Scars? What causes their formation?
Hypertrophic scars are produced through any cases of abnormality during the healing process, this especially occurs when the deep dermis is affected by burns.
The tension in a healing wound causes a hypertrophic scar. A thick layer of skin is formed. In a typical wound, the equilibrium stage is reached thanks to anabolic and catabolic processes approximately 6-8 weeks after the original injury.
