Skin covers the entire body, and acts as a protective barrier. Scar tissue forms as skin heals after an injury (such as an accident), acne, or surgery. The amount of scarring may be determined by the size, depth, and location of the wound; the age of the person; heredity; and skin characteristics including color (pigmentation). No scar can be removed completely. The degree of improvement will depend on variables such as the direction and size of the scar, the age of the person, skin type and color, and hereditary factors that may precondition the extent of the healing process.

What happens when healthy skin is injured?

When an injury occurs, at least one of the skin layers is involved. In a simple wound, the healing process begins with bleeding into the wound and clot formation. The body receives a signal for repair, and the area becomes swollen and sore. As repair continues, small tissue fibers form, eventually becoming solid tissue that may result in a scar.

What is the difference between a hypertrophic scar and a keloid scar?

Both types of scars are raised. Hypertrophic scars are elevated above the surface of the skin, but confined within wound boundaries. Keloid scars are similar to hypertrophic scars, except that they extend beyond the boundaries of the original wound into surrounding skin areas.

What are other causes of scars?

Not all scars are caused by wounds, burns, surgeries, and accidents. Skin diseases caused by bacteria, fungus, or viruses can also result in scarring. Acne is a good example of a skin disease that leaves scars. Stretch marks are an example of scars caused by weight change or growth.

Are some people more prone to developing scars?

Scarring is a part of the natural healing process. Based on personal history or medical conditions, some people are more likely to develop problem scars. Two reasons for problem scarring are improper cleaning of the wound and further injury to the wound site. Other things such as location of the scar, poor nutrition, skin coloration, and age are also contributing factors.

What are the Common Treatment for Scars?

Common treatments for scars are laser surgery,  cosmetic and reconstructive surgery, and steroidal creams. The average treatment for scars using cosmetic and reconstructive surgery range from $2,500 to over $20,000.
