Keloid Scar: Why They Form and How Renew Treat Them Effectively

Medically reviewed by Dr. Nawal Kishore Jha, Lead Dermatologist at Renew Skin & Health Clinic, Leamington Spa.

A scar that keeps growing, itching, or thickening long after a wound has healed can be confusing and, for many people, a source of real self consciousness. This is often the story of a keloid scar, a raised, overgrown scar tissue that behaves very differently from an ordinary scar. Whether you are dealing with a single small keloid scar on an earlobe from a piercing or a larger one on the chest or shoulder, understanding why it forms is the first step towards treating it effectively.

At Renew Skin & Health Clinic in Leamington Spa, we see patients from across the UK who are looking for clear answers and safe, personalized treatment for keloid scarring. In this guide, we explain what causes keloid scars, how they differ from normal scars, and the treatment options our specialists use to reduce their Size and appearance.

A Keloid scar is a hard, elevated region of scar tissue that forms as the skin creates excessive collagen in the process of healing. In contrast to a normal scar that stays within the limits of the wound, however, a keloid can extend beyond the boundaries of the wound and may grow over a period of months, or perhaps years.

Keloids are usually smooth on the surface and can appear pink, red, purple, or darker than the surrounding skin, depending on your natural skin tone. They can develop after almost any form of skin trauma, including:

• Ear piercings
• Surgical incisions
• Acne breakouts
• Burns
• Cuts, scrapes, or insect bites
• Vaccination sites

Some scars remain small and localized, while others grow into large, raised areas that extend well beyond the original wound.

The exact reason some people develop keloid scars while others heal with a flat, faint scar is still being researched, but several contributing factors are well recognized:

1. An Overactive Healing Response

During normal healing, the body makes collagen to help repair skin damage. For people who are susceptible to Keloids, this process does not stop at the appropriate time, and collagen continues to build and create thickened, raised tissue.

2. Genetics and Family History:

If your parent or sibling has been diagnosed with keloid scars, you are more likely to develop them as well. This genetic link is among the most powerful recognized risk factors.

3. Skin Tone

Keloid scars are more common in people with darker skin tones, although anyone, regardless of ethnicity, can develop one.

4. Location of the Injury:

Certain areas of the body are more prone to keloid formation, including the chest, shoulders, upper back, earlobes, and jawline, likely due to skin tension in these regions.

5. Age:

Keloids most frequently develop in people between the ages of 10 and 30, although they can appear at any age.

Not every keloid looks the same, and the Size of the scar often influences which treatment is recommended.

Small keloid scars typically develop after minor trauma such as ear piercings, small cuts, or acne lesions. They are often raised, firm, and localized to a small patch of skin, but they can still itch, feel tender, or catch on clothing and jewellery. Many patients are surprised that even a small keloid scar can be persistent and slow to respond to home remedies, which is why an early professional assessment is worthwhile.

Larger keloid scars are more likely to appear following surgical incisions, burns, or more severe skin injuries. They can extend far beyond the initial wound, and then become more firm as time passes and may require an array of treatments to treat effectively.

Regardless of Size, keloid scars rarely disappear without some form of intervention, so understanding your options early can help prevent further growth.

While the appearance of a keloid can vary from person to person, common symptoms include:

• Raised, thickened, or lumpy scar tissue
• A smooth, shiny skin surface
• Itching or a prickling sensation
• Tenderness or discomfort, especially with friction
• Gradual enlargement beyond the original wound
• A firm texture that may feel tight when the skin moves

If you notice a scar that continues to grow, itches persistently, or feels increasingly firm, it is worth having it assessed by a dermatology specialist.

Keloid scars are not usually a medical danger and are not cancerous. However, they can cause ongoing physical discomfort, restrict movement if they form over a joint, and affect a person’s confidence, particularly when they develop on visible areas such as the face, neck, or ears. For these reasons, many people choose to pursue treatment for both comfort and cosmetic reasons rather than leaving a keloid untreated.

At Renew Skin & Health Clinic, our specialists assess every keloid scar individually before recommending a treatment plan, taking into account its Size, location, age, and your skin type. We offer several evidence based options, often combined for the best long term results.

1. Laser Treatment for Keloid Scars

Laser therapy is among the most popular methods for keloid scar reduction. It targets the scar tissue in order to improve its texture, flatten the surface, and reduce redness, with a minimum of downtime. This procedure is especially popular for patients who have small keloid like scars on the face or ears, where the most precise minimally invasive procedure is preferred.

2. Steroid Injections

Corticosteroid injections are a great option to decrease inflammation and excessive collagen production in the scar. The injections relax and smooth the keloid following several sessions. They are often utilized in conjunction with other treatments to get more effective results.

3. Surgical Keloid Removal

For more extensive or established scars from keloid, surgical removal could be the best option. The procedures we offer are performed by highly skilled plastic surgeons registered on the GMC specialist register. They are often followed by follow up treatments, such as laser therapy or steroid injections, to minimize the risk of keloid recurrence.

4. Combination Therapy

Many of our patients achieve the best long term outcomes through a combined approach, such as surgical removal followed by steroid injections and laser therapy. This integrated strategy is especially useful for larger keloids or scars that have previously returned after a single treatment.

Every treatment plan begins with a thorough, personalized consultation. Our specialists will examine the scar, discuss your medical and healing history, and explain the realistic outcomes you can expect based on the Size and location of your keloid. Treatment for keloid scars at Renew Skin & Health Clinic starts from £175, with the final cost depending on the Size, type, and location of the scar.
