Keloids & Hypertrophic Scars: Causes, Symptoms, Diagnosis, and Treatment

What Are Keloids & Hypertrophic Scars?

Keloids & Hypertrophic Scars are types of raised scars that form after skin injuries. Both can look similar, but they have key differences. Keloids grow beyond the original wound, while hypertrophic scars stay within the wound area. Many people want to know the difference between keloids and hypertrophic scars. Understanding these scars helps you choose the right care and treatment.

Symptoms and Appearance

Both keloids and hypertrophic scars can look raised and thick. However, there are some differences in how they appear. For example, keloids often:

  • Grow larger than the original wound
  • Feel firm or rubbery
  • Look shiny or smooth
  • Appear pink, red, or dark brown

    • On the other hand, hypertrophic scars:

  • Stay within the wound area
  • May be red or pink at first
  • Can flatten over time

    • Sometimes, these scars can itch, hurt, or feel sensitive. But not everyone has symptoms.

    Causes and Risk Factors

    Scars form as the skin heals after an injury. Sometimes, the body makes too much collagen, a protein that helps skin heal. This extra collagen causes keloids & hypertrophic scars. Several factors can increase your risk:

  • Family history of keloids
  • Darker skin tones
  • Young age (10–30 years old)
  • Injuries from cuts, burns, piercings, or surgery

    • Still, not everyone with these risk factors will develop scars. But knowing your risk can help you take steps to prevent them.

    Diagnosis

    Doctors usually diagnose keloids & hypertrophic scars by looking at your skin. They may ask about your medical history and how the scar formed. Sometimes, a skin biopsy is needed to rule out other problems. However, most cases do not need special tests. Early diagnosis helps you get the best treatment for your scar type.

    Treatment Options

    Many people ask about keloid scar treatment and the best treatments for hypertrophic scars. Treatment depends on the scar type, size, and location. Options include:

  • Silicone sheets or gels: These can flatten and soften scars over time.
  • Steroid injections: These help reduce swelling and make scars less noticeable.
  • Laser therapy: This can improve color and texture.
  • Surgery: Doctors may remove large scars, but keloids can return.
  • Cryotherapy: Freezing the scar can help shrink it, especially for small keloids.
  • Pressure therapy: Special dressings can help prevent scars after burns or surgery.

    • Sometimes, doctors use more than one treatment. But results can vary. Always talk to a dermatologist about your options.

    Prevention Tips

    While not all scars can be prevented, you can lower your risk. Here are some tips on how to prevent keloids and hypertrophic scars:

  • Care for wounds right away by keeping them clean and covered
  • Avoid picking at scabs or scratching healing skin
  • Use sunscreen on scars to prevent darkening
  • Tell your doctor if you have a history of keloids before surgery or piercings
  • Follow your doctor’s wound care instructions closely

    • Even with good care, some people may still develop scars. But early action can help reduce their size and appearance.

    Living with Keloids & Hypertrophic Scars

    Living with keloids & hypertrophic scars can affect how you feel about your skin. Sometimes, these scars can cause discomfort or make you feel self-conscious. However, many people find ways to manage their scars and boost their confidence. For example, you can:

  • Talk to your doctor about new treatments
  • Use makeup or clothing to cover scars if you wish
  • Join support groups to connect with others

    • Remember, you are not alone. Many people have scars, and help is available.
