Scar Removal Basics – Key Concepts
One of the most misunderstood skin health issues is the issue of skin scarring. Scars are always a result of wounds and, therefore, is experienced by all. Small scratches or cuts may be an exemption but majority of skin injuries turn into scar tissues.
Scar tissues are composed of fibrous tissues that replace the normal skin tissues that get damaged. It is made of weaker material than those it replaces and will contain no hair follicle, sweat and oil glands. The skin loses those adaptive facilities when it becomes scarred. This is why scars are said to be more prone to destructive elements like the ultraviolet rays of the sun. We should take good care of scars and keep them protected against excessive sun exposure.
The underlying mechanism of scar formation involves inflammation, excessive fibroblast proliferation and over expression of collagen. When skin starts to heal, it lays down new collagen fibers which make up the fibrous connective tissue of healthy skin. In scars collagen over expresses and gives scar that distinct look from normal skin.
The appearance of the scar will depend on the severity of the wound but in most cases, scar tissue will only take the shape of the original wound and will not go beyond it. It is also expected to fade with sufficient time. Some may take only weeks to disappear but for some it may take years. It all depends on the person’s capacity for healing and the severity of the original injury itself.
Unfortunately, for a certain percentage of scars, over production of collagen results in abnormal-looking scars that are characterized by reddish bumps on the skin that cover the area of the original skin injury and never goes beyond. These are known as hypertrophic scars.
Another type of scarring called keloid scars are probably the worst kind because they can grow beyond the boundaries of the original wound. They could grow indefinitely to form tumorous growths. Although they are benign tumors and are harmless, some people may find it imperative to do something about them.
On the other hand, recessed scars are types of scars that have the sunken and pitted appearance that are the opposite of hypertrophic scars. This type of scarring is usually a result of skin disease like acne or chicken pox.
Scars that are normally seen in pregnant women are called stretch marks. Also known as striae, these are scars that result from skin that being stretched out too fast. These are also seen in people undergoing rapid weight gain and growth. They are expected to disappear after some time.
