Keloids are scars that grow beyond the boundaries of the original site of injury. They cause discomfort, restricted movement, and tightness, mainly when they occur around a joint such as the knee or ankle. Though these raised scars grow excessively, they do not adversely affect health per se, but they could be a cosmetic concern. The good news is that due to medical advances keloid scar management is possible today.
What Are Keloids?
Keloids are an abnormal type of scars that grow beyond the boundary of the wound and become much larger than the original injury. The scar becomes raised, thick and grows excessively during the healing process of the wound. Anything that can cause scarring can lead to keloids in predisposed individuals. This includes burn injuries, severe acne, cuts or surgery. Keloids can also develop after going for a tattoo or body piercing. Keloids can affect any part of the body and take a few weeks to three months to fully develop. Some keloids even continue to grow afterward. Keloids are the trickiest scars to manage.
What Are The Causes And Symptoms Of Keloid Scars?
To find out the right treatment options, here are a few things you should know about keloids.
Causes Of A Keloid Scar:
It is a result of different kinds of injuries. These include –
- Surgical Scars
- Severe Acne
- Puncture Wounds
- Vaccination Sites
- Chickenpox Scars
- Insect Bites
Spontaneous keloids are those keloid scars that form without an injury preceding them. They also develop due to a genetic propensity. You are more likely to develop keloids if either of your parents had it. Also, people with darker skin tones (primarily individuals of Latin, South Asian, and African descent) are 15 to 20% more likely to develop keloids than others.
Symptoms Of A Keloid Scar:
Keloids typically begin as raised scars with flat or round surfaces and are red, pink or purple in color. The border is often darker than the center. Overall, it has the following characteristics –
- Abnormal wound healing precedes the slow emergence of a keloid that expands over time.
- Raised overgrowth with a flat or round surface.
- Commonly occurs on the neck, shoulder, chest, back, and ears.
- Ranges in texture from soft and doughy, or hard and rubbery to the touch.
- Accompanied by itchiness, pain, and tenderness around the wound.
- Scar tissue is reddish or pink.
- Range in size varies from less than an inch to more than 12 inches.

What Is The Texture And Feel Of Keloid Scars?
A keloid scar has a smooth, flat, and firm surface. The skin may feel sore to touch until it develops fully. The pain usually subsides once it stabilizes. Sometimes, keloids often disguise as bacterial infections or skin tumors.
Keloids Vs Hypertrophic Scars
Here are some of the fundamental differences between the two types of scars:
- Keloids extend beyond the boundary of the injury site whereas a hypertrophic scar is a widened raised scar that stays within the extent of the original wound.
- Unlike keloid formation, hypertrophic scars do not correlate with a racial or genetic predisposition.
- Hypertrophic scars respond well to treatment, while keloids are relatively challenging to eliminate.
How Are Keloids Treated?
Keloid removal treatment works by shrinking the keloid. Once it flattens and softens, it can be easier to get rid of to an extent. Treatment depends upon the site, extent of involvement, age of the individual and duration of the scar. Usually, doctors prefer using a combination of procedures that include –
1. Laser Therapy:
It is often considered as the best treatment for keloid scar and other kinds of scarring on the skin due to its non-aggressive approach. A Pulsed dye laser (PDL) beam directed at the scar tissue can help to reduce the redness, size, and appearance of the keloid. Dermatologists often use it in conjunction with steroid injections.

2. Steroid Injections:
Doctors administer steroid injections such as triamcinolone into the scar. They decide the dosage and amount of injectable needed for scar reduction. These injections show results when administered at regular intervals.
3. 5-Fluorouracil Injections:
Doctors use this option either as a stand-alone treatment or in combination with the steroid triamcinolone for reduction of keloids. They administer the injections at 3-4 week intervals. Your dermatologist will decide the dosage you need depending on the extent and hardness of the keloid.
4. Silicone Gel Dressing:
Silicone dressing treatment involves the application of a silicone gel or sheet. The procedure is affordable, and usually, doctors combine it with other methods to attain the best results.
In this treatment option, a dermatologist will apply a liquefied gas, i.e. liquid nitrogen at freezing temperature, to the scar tissues at regular intervals, to shrink them radically. Sometimes the doctor may instill the liquid directly into the scarred tissue as well.
