Understanding Keloids: What They Are and How They Form

A keloid is a type of scar that grows larger than the original wound or injury. Unlike normal scars that fade and flatten over time, keloids continue to expand beyond the boundaries of the initial injury. This overgrowth of scar tissue occurs because the body produces too much collagen during the healing process. The result is a raised, firm, often shiny bump on the skin that can be pink, red, purple, or darker than the surrounding skin.

Keloids develop when the body's natural healing response becomes overactive. When skin is injured—through surgery, piercing, tattooing, acne, burns, or even minor cuts—the body sends signals to produce collagen to seal the wound. In people prone to keloid formation, this process doesn't stop at the right time. The excess collagen keeps accumulating, creating a growth that extends beyond the original wound edges. This is different from a hypertrophic scar, which stays within the boundaries of the initial injury and may fade somewhat over time.

Several factors increase the risk of developing keloids. Genetics plays a major role—people with darker skin tones are 15 times more likely to develop keloids than those with lighter skin. Age matters too; keloids form most often between ages 10 and 30. Location on the body affects risk as well. Areas with high tension or movement, such as the chest, shoulders, upper back, and earlobes, are more prone to keloid formation. Certain body parts naturally have more keloid risk, with the upper chest and shoulders accounting for nearly 65% of all keloids.

Keloids can appear months or even years after the original injury. Some people may get a keloid from a minor injury they barely remember, while others with similar injuries never develop one. The size of keloids varies greatly—some are small and barely noticeable, while others can grow to several inches across. Beyond appearance, keloids can cause physical discomfort, including itching, tenderness, and pain. In some cases, they may limit movement if they form over joints.

Practical takeaway: Understanding what keloids are helps you recognize them early and seek treatment. If you notice a scar that keeps growing after an injury has healed, or if you have a family history of keloids, monitor the area closely and consider discussing treatment options with a dermatologist.

Medical Treatments: Injections and Topical Options

Steroid injections are one of the most commonly used medical treatments for keloids. Dermatologists inject corticosteroids directly into the keloid tissue to reduce inflammation and flatten the scar. Triamcinolone acetonide is the steroid most frequently used for this purpose. The treatment works by decreasing collagen production and shrinking the scar tissue. Most patients require multiple injections spaced 4 to 6 weeks apart. Studies show that steroid injections alone result in complete flattening in about 50% to 60% of cases, with improvement in an additional 20% to 30% of patients.

The steroid injection process is relatively straightforward. A dermatologist cleans the area and may apply a topical anesthetic to reduce discomfort. The steroid solution is then injected into the keloid using a fine needle. The procedure takes only a few minutes. Side effects are generally mild and may include temporary pain, redness, or slight bruising at the injection site. In rare cases, steroid injections can cause skin atrophy (thinning) or hypopigmentation (lightening) if injected too close to the skin surface, though experienced dermatologists know how to minimize this risk.

Topical treatments offer non-invasive options, though they work best for mild or newly forming keloids. Silicone gel sheets are applied directly to the scar and create a moist environment that may help soften and flatten scar tissue over several months. These sheets are worn for 12 or more hours daily and can be purchased without a prescription. Onion extract creams, such as those containing Mederma, have shown modest benefits in some studies for reducing scar appearance, though results vary widely. Topical retinoid creams may also offer some improvement when used consistently over time.

Combination therapy often produces better results than single treatments. Many dermatologists combine steroid injections with other approaches to address keloids from multiple angles. For example, a patient might receive steroid injections followed by pressure garments or silicone application. Some clinics use a combination of steroid injections with topical 5-fluorouracil (5-FU), a medication that further reduces collagen production. This multimodal approach increases the likelihood of significant improvement or complete resolution.

Practical takeaway: Steroid injections are a first-line treatment for many keloids and require multiple appointments over several months. If you choose this route, plan for a series of treatments and discuss realistic expectations with your dermatologist, as results vary based on keloid size, location, and individual skin characteristics.

Surgical and Ablative Removal Methods

Surgical excision involves cutting out the keloid tissue under local anesthesia. While this seems like a straightforward solution, surgery alone carries significant risk—keloids return in 45% to 100% of cases where surgical excision is the only treatment used. This happens because the surgical wound itself can trigger the same overactive healing response that created the original keloid. However, surgery combined with other treatments shows much better results. When excision is followed by steroid injections or radiation therapy, recurrence rates drop dramatically to 10% to 20%.

Laser therapy offers another removal option, particularly for smaller or early-stage keloids. Different types of lasers work in different ways. The pulsed dye laser targets blood vessels in the keloid, reducing redness and potentially shrinking the tissue. Ablative lasers like the CO2 laser vaporize the top layers of scar tissue. Fractional laser treatments create tiny treatment zones within the keloid, stimulating healing while minimizing damage to surrounding skin. Most patients require multiple laser sessions spaced several weeks apart. Laser treatments are less invasive than surgery and carry lower recurrence rates, though they may not completely eliminate larger keloids.

Cryotherapy, or freezing, destroys keloid tissue by exposing it to extremely cold temperatures. Liquid nitrogen is applied directly to the keloid, damaging the cells and causing the scar to flatten over time. This treatment works best on smaller keloids and typically requires multiple sessions. Cryotherapy causes temporary blistering and may result in temporary or permanent lightening of the skin in the treated area, which is a particular concern for people with darker skin tones.

Radiation therapy is used in specific situations, particularly when keloids are very large, in high-risk locations, or have recurred after other treatments. Low-dose radiation is delivered to the keloid area, usually within one to two weeks after surgical excision. The radiation prevents the overactive healing response from occurring. However, radiation is generally reserved for severe cases due to potential long-term risks and is less commonly used than other methods. When used appropriately, radiation can prevent keloid recurrence in up to 85% to 90% of cases.

Practical takeaway: Surgical removal alone is not recommended because keloids frequently return after surgery. If you're considering surgical options, ask your dermatologist about combining surgery with follow-up treatments like steroid injections or radiation to significantly reduce the chance of the keloid returning.

Prevention Strategies and Aftercare for Wound Healing

For people at high risk of developing keloids, prevention during the healing process is crucial. This starts immediately after any skin injury or medical procedure. Keeping the wound clean and moisturized supports healthy healing and may reduce keloid risk. Some research suggests that applying pressure to a healing wound through compression garments or bandages can help direct healing in a way that minimizes excessive scar tissue buildup. Pressure should be applied consistently and maintained for several weeks to months as the wound heals.

Protecting wounds from tension and movement aids healing. If possible, avoid activities that stretch or stress the healing area. For example, people who develop keloids from piercings should not wear heavy earrings or change jewelry frequently during healing. Those prone to keloids should wait longer than standard healing times before resuming activities that stress the area. Many dermatologists recommend waiting 6 to 12 months after a piercing before changing jewelry if you're keloid-prone, compared to the standard 6 to 8
