Scarring is part of the wound healing process, which can arise for a variety of reasons. Can be caused by smallpox scars, wounds from acne, burns, to post-operative wounds.
Many factors affect the occurrence of scarring, ranging from depth, breadth, to the location of the wound. Scarring is formed when there is significant skin damage that changes the normal skin tissue in recovery. Age, heredity and gender factors also influence how the skin reacts to respond to wounds.
Scarring Is Affected by Various Factors
There are many factors that affect the appearance of scarring on the skin. Scar tissue that grows can also have different shapes, depending on the type of injury that causes it. The following are some common types of scarring:Keloids
Keloids are scar tissue that is formed excessively due to injuries to the skin, and its size can exceed the size of the wound that causes it. Generally, keloids appear due to acne scars, ear piercing, chicken pox scars, postoperative scars and burns. Keloid scarring is characterized by thickening of the skin on the scar with a color that is quite contrasting with the surrounding skin. Keloids in exposed skin areas exposed to sunlight tend to be darker in color. That's why keloids are often thought to interfere with appearance, rather than cause health problems.
Hypertrophic
Hypertrophic scar tissue has a shape that almost resembles keloids. However, hypertrophic scar tissue tends to be lighter and not grow beyond the limit of skin injury.
Contracture
Contractures in the wound are scar tissue that can form due to burns, where there is shrinkage or shortening of skin tissue. Not only forming scar tissue, burns can also cause interference with the subcutaneous tissue. Contractures can injure muscle and nerve tissue so that it is not uncommon to cause limited movement of injured body parts.
