Keloid scars: Causes, Risk Factors, Symptoms, Treatment

Keloid scars

Keloid scars are a specific type of scar that can develop after an injury or trauma to the skin. Unlike regular scars, keloids extend beyond the boundaries of the original wound and can become raised, thickened, and sometimes even larger than the initial injury. These scars are caused by an overgrowth of collagen during the healing process. They often appear shiny, smooth, and have a reddish or purple coloration. Keloid scars can be itchy, tender to touch, and may cause discomfort or pain. It is important to note that keloid scars are more common in individuals with darker skin tones and can occur anywhere on the body. They can result from various types of injuries such as surgical incisions, burns, acne lesions, piercings, or even minor cuts. While keloid scars do not pose any serious health risks, they can be bothersome from an aesthetic standpoint and may affect one's self-confidence. Treatment options for keloids include corticosteroid injections, silicone gel sheets or dressings, cryotherapy, laser therapy, surgical removal (excision), or radiation therapy. If you suspect you have a keloid scar or are concerned about its appearance or symptoms, it is recommended to consult with a dermatologist who can provide proper diagnosis and guidance on suitable treatment options tailored to your specific situation.

Symptoms of Keloid scars

If you suspect you or someone else is experiencing Keloid Scars, it is crucial to seek immediate medical attention by calling emergency services or consult with a Dermatologist.


Keloid scars are a common skin condition that can have a significant impact on a person's self-esteem and quality of life. Understanding the causes of keloid scars is essential in developing effective treatment strategies and prevention methods. Keloid scars occur when the body's natural healing process goes awry, leading to an overproduction of collagen in the affected area. While any type of injury or trauma to the skin can potentially result in keloid formation, certain factors increase the likelihood of developing these raised, thickened scars. One of the primary causes of keloids is genetics. Individuals with a family history of keloid scarring are more prone to developing them themselves. This suggests that there may be specific genes involved in regulating collagen production and wound healing processes. Also, certain ethnicities, such as individuals with darker skin tones, have a higher predisposition to keloids. This indicates that there may be underlying genetic and biological factors at play in addition to environmental triggers. Other potential causes include excessive tension on the wound site during healing, such as from surgical procedures or ear piercings. Additionally, infections or inflammation at the site of an injury can contribute to keloid formation.

Risk Factors

Keloid scars are a common concern for many individuals, and understanding the risk factors associated with their development is crucial in managing and preventing their occurrence. By delving into these risk factors, we can gain valuable insights into who may be more susceptible to keloid scarring and take proactive measures to minimize their impact. One significant risk factor for keloid scars is genetics. Research has shown that individuals with a family history of keloids are more likely to develop them themselves. This suggests a genetic predisposition that influences how the body responds to injury or trauma, leading to an overproduction of collagen during the healing process. Another important risk factor is the location of the wound or injury. Keloids tend to form more frequently in areas where there is increased tension on the skin, such as the chest, shoulders, earlobes, and upper back. This tension disrupts the normal healing process and contributes to excessive scar tissue formation. Understanding these risk factors helps take proactive measures towards prevention and management of keloid scars. By identifying those who may be at higher risk based on genetics or ethnicity, healthcare professionals can provide targeted interventions such as early treatment options or counseling on wound care techniques that minimize scar formation.


Keloid scars, though not harmful to one's health, can be a source of discomfort and self-consciousness for many individuals. Understanding the symptoms associated with keloid scars is crucial in order to effectively manage and treat them. One of the primary symptoms of keloid scars is their appearance. Unlike regular scars that tend to fade over time, keloids are characterized by their raised, thickened, and sometimes shiny texture. They often extend beyond the boundaries of the original wound or injury, creating a noticeable and sometimes unsightly mark on the skin. In addition to their physical appearance, keloid scars can also cause itching, tenderness, or even pain. This discomfort can be exacerbated by factors such as friction from clothing or accessories rubbing against the scarred area. It is important to note that not everyone who develops a scar will experience keloid formation. However, for those who are prone to developing keloids, it is essential to be aware of these symptoms in order to seek appropriate medical advice and treatment options.

Diagnosing keloid scars is an essential step in understanding and treating this unique skin condition. With advancements in medical technology, healthcare professionals now have a range of diagnostic tools and techniques at their disposal to accurately identify keloid scars. One common method used for diagnosis is a visual examination by a dermatologist or plastic surgeon. They will carefully assess the appearance of the scar, noting its size, shape, texture, and color. Additionally, they may inquire about the patient's medical history and any previous trauma or surgical procedures that may have contributed to the development of the keloid scar. In some cases, imaging tests such as ultrasound or MRI scans may be recommended to evaluate the underlying tissue and determine the extent of the keloid scar's growth. These tests can provide valuable insights into any potential complications or other factors that may be influencing the scar's progression. Also, a skin biopsy may be performed to confirm the diagnosis of a keloid scar. During this procedure, a small sample of tissue is extracted from the affected area and examined under a microscope. This helps rule out other similar skin conditions and ensures an accurate diagnosis.


When it comes to treating keloid scars, it is important to explore various options that can effectively address this common skin condition. Keloid scars are characterized by their raised and thick appearance, extending beyond the original wound or injury site. While they do not pose any health risks, keloid scars can be a source of discomfort and self-consciousness for many individuals. Also, there are several treatment options available that can help reduce the size and appearance of keloid scars. One commonly used approach is corticosteroid injections, which work by reducing inflammation and flattening the scar tissue. These injections are typically administered by a dermatologist or healthcare professional. Another treatment option is silicone gel sheets or dressings. These products create a protective barrier over the scar, helping to flatten and soften its appearance over time. They are often recommended for long-term use to achieve optimal results. In addition to these non-invasive treatments, more advanced procedures such as laser therapy and cryotherapy may also be considered for larger or more stubborn keloid scars. Laser therapy uses focused light energy to break down scar tissue and stimulate collagen production, while cryotherapy involves freezing the scar tissue with liquid nitrogen to encourage its removal.

Preventive Measures

Prevention is key when it comes to managing and dealing with keloid scars. These raised, thickened scars can be not only physically uncomfortable but also emotionally distressing for individuals who have them. By taking proactive measures, we can significantly reduce the risk of keloid formation and promote healthier skin healing. One effective way to prevent keloid scars is by avoiding unnecessary trauma or injury to the skin. This means being cautious during activities that may cause cuts, burns, or other types of skin damage. By practicing good wound care and promptly treating any injuries, we can minimize the chances of keloids forming. Additionally, keeping the skin well-moisturized and hydrated is crucial in preventing keloids. Dry skin tends to be more prone to scarring, so regularly applying moisturizers or creams can help maintain the skin's elasticity and promote proper healing. Another preventive measure is protecting the affected area from excessive sun exposure. UV rays can worsen the appearance of scars and increase their visibility. Using sunscreen with a high SPF and covering up with clothing or accessories like hats can shield the scarred area from harmful sun rays. In some cases, medical interventions such as silicone gel sheets or corticosteroid injections may be recommended by healthcare professionals for individuals at higher risk of developing keloids. These treatments help flatten existing scars and prevent new ones from forming.
