Hypertrophic Scar & Keloid

Both hypertrophic scars and keloids are thick raised scars caused by the body producing too much collagen during skin healing injuries like cuts, burns, surgical cuts, or acne. Typically, new skin cells will develop as the wound heals, however, deeper injuries may prompt the body to generate collagen to repair the wound. If the body produces too much collagen, it will result in a raised scar.

Genetics has been linked to an increased chance of developing hypertrophic scars or keloids in certain individuals, with Asian and African having the highest chance compared to Hispanic or Mediterranean descent. Other contributing factors include skin tension, inflammation, and hormonal changes.

Differences Between Hypertrophic Scars and Keloids

Hypertrophic scars and keloids often cause itchiness and discomfort, but the main difference between them both is the spread of the scar. Hypertrophic scars stay within the original wound and may gradually improve over time. On the other hand, keloids grow beyond the wound area months to years after injury and can be painful. Here are some differences between the two scars:

Hypertrophic scars and keloids tend to develop in areas of the body where the skin heals under tension, such as ears, back, chest, shoulders, upper arms, elbows, and around joints.

Treatment Options for Hypertrophic Scar & Keloid

The purpose of treatments is to flatten, soften or minimize the size or alleviate the pain and itch of the scar. Other than applying creams or gels to help reduce pain or itch, you can also use:

Silicone sheets

To be worn daily to help flatten and soften scars over time.

Steroid Injections

Corticosteroids are injected directly into the scar to reduce inflammation and flatten the scar. A few injections are taken a few weeks apart.

Laser Therapy

Laser treatments are used to reduce the redness of scars by targeting the blood vessels in the scar and stopping scar from growing.

Cryotherapy

Freezing the scar and destroying scar tissue to flatten it.

Surgical Excision

For severe cases in which non-invasive treatments are ineffective, scars may have to be removed surgically. This is usually combined with other treatments for better results.

How To Prevent or Lessen Scarring

It is important to practice good wound care in order to reduce the chance of forming hypertrophic scars or keloids. Keeping wounds clean, moist, and covered will help the healing process. Avoid picking at scabs or scratching healing wounds. If you are concerned that the keloids may be masking a skin cancer, or the scarring is either affecting your self-esteem or restricting your movement, you should consider consulting a dermatologist to get them removed safely.
