Hypertrophic scars and keloids are a result of excess collagen production to an area of recent trauma or wound. Hypertrophic scars tend to stay within the region of the cut or injury so only that area is discolored. This differs from keloids because keloids tend to move outside of the area of injury. These scars typically form around areas of movements such as joints and the face and ears, upper arm, and back because of muscle and skin tension.
Keloids are raised scars above the skin at the sight of the injury. Although hypertrophic scars are also raised keloids extend out farther and are darker in color and more noticeable. This is the main way to tell the difference between the two. Keloids always go beyond the region of injury and leave a scar that extends more than 4mm from the skin. Hypertrophic scars tend to be pink or red in color while keloids are usually a little darker pink or purple color. Keloid scars can sometimes cause irritation and discomfort due to them rubbing against clothing. In certain cases, keloids will continue to grow and get bigger over time. This is another sign to know that this is a keloid and not a hypertrophic scar.
Individuals with darker pigmentation such as African Americans, Hispanics, and Indians; have a higher risk of keloid formation. Experts are not sure what exactly causes the formation of these scars or prevention. Those with fair skin have a higher risk or hypertrophic scars.
The most common treatment for keloid and hypertrophic scars is silicon. Silicon gel or sheets helps keeps the area hydrated and reduces collagen production. Keloids can be surgically removed and treated in combination with steroid injections and radiation therapy to help reduce the recurrence of them. Hypertrophic scars tend to go away on their own most times.
