Types of Scar Tissue

Types of Scar Tissue

How an individual scar looks depends on a few things, including the circumstances of the injury and a person’s skin tone. For instance, a puncture wound causes a different looking scar than a burn wound, and whether the wound gets infected or not can also influence the appearance of the scar. A wound in a place w

here the skin is stretched tight, like the chest, often causes a thicker scar, since the body has to make more tissue to keep the wound from pulling open. Skin tone plays a role too. Though scars in general tend to turn white over time, those with dark skin may get scars that get darker with time. Those with darker skin may also be more prone to keloid scars.

There are five main types of scars:

Atrophic scars: These scars are sunken down into the skin. This type of scarring is often seen with acne scars or with wounds where skin or muscle is removed by an injury. This type of scarring can also happen when the body produces so much scar tissue in one area that it prevents new cells from growing where the wound took place.

Hypertrophic scars: These are usually red or purple and are slightly raised above the skin. They tend to fade and get flat over time.

Contracture scars: These types of scars often happen with burns, and end up pulling the skin in towards the site of the injury. This can make the skin look puckered around the wound.

Keloid scars: These are very elevated, red or dark scars that form when the body produces a lot of extra collagen in a scar. Keloid scars are actually a benign type of tumor, and often grow bigger than the area of the original injury. Those with darker pigmented skin are thought to be more prone to keloid scarring, but it’s not clear why.

Stretch marks: Also called striae, these are considered a unique type of scar since they don’t happen in response to an injury, but because of the skin being stretched rapidly, often during pregnancy or adolescence. The tissue here is often sunken a little into the skin, and tends to fade with time.
