The Bottom Line

Keloids — raised, firm scars that grow beyond the boundaries of the original wound — are 5-15 times more common in people with darker skin tones, particularly those of African, Asian, and Hispanic descent. Managing keloids in skin of color requires a multi-modal approach: steroid injections to shrink active keloids, silicone sheets for prevention, pressure therapy for ear keloids, and surgical excision combined with post-operative treatment to prevent the high recurrence rates. No single treatment works alone — combination therapy produces the best results.

What Are Keloids and Why Are They More Common in Skin of Color?

Keloids are an abnormal wound healing response where the body produces excessive collagen at a wound site, creating a raised, firm scar that extends beyond the original wound boundaries. Unlike hypertrophic scars (which stay within the wound borders), keloids invade surrounding normal tissue and rarely resolve on their own.

Keloids affect people of African descent at 5-15 times the rate of Caucasian populations. They are also significantly more common in Asian, Hispanic, and Mediterranean populations. The genetic basis is complex — multiple gene variants affecting wound healing and fibroblast behavior have been identified, though no single gene fully explains the predisposition.

Common keloid triggers include surgical incisions, ear piercings (one of the most common causes), acne, burns, vaccinations, insect bites, and tattoos. Some people develop keloids spontaneously without any identifiable trigger. High-risk body areas include the earlobes, chest/sternum, shoulders, upper back, and jawline.

Signs of Keloids vs. Normal Scars

Keloid characteristics: Extends beyond the original wound borders, firm and rubbery texture, raised above surrounding skin level, may be pink, red, brown, or darker than surrounding skin, often itchy or tender, continues to grow slowly over months to years, and does NOT resolve on its own.

Hypertrophic scar (different): Stays within the wound borders, may be raised but typically flattens over 12-24 months, and may improve spontaneously. The distinction matters because treatment approaches differ.

Treatment Options for Keloids in Skin of Color

Intralesional corticosteroid injections (first-line):

Triamcinolone acetonide (10-40 mg/mL) injected directly into the keloid every 4-6 weeks for 3-6 sessions. This is the most common and effective initial treatment, producing 50-80% improvement in size and symptoms. Side effects include temporary skin lightening at the injection site (hypopigmentation) and skin thinning (atrophy) — both more noticeable on darker skin. Using the lowest effective concentration and precise injection technique minimizes these risks.

Silicone sheets and gel (prevention and adjunct):

Medical-grade silicone worn 12-24 hours daily for 3-6 months. Effective for both preventing keloid formation (after surgery on keloid-prone patients) and treating existing small keloids. Creates an occlusive environment that normalizes collagen production. Best started 2-4 weeks after wound closure.

Pressure therapy:

Sustained compression using custom earrings (for ear keloids), pressure garments, or compression bandages. Applied 12-24 hours daily for 6-12 months. Reduces blood flow and growth factor delivery to the keloid. Particularly effective for ear keloids after surgical excision — reduces recurrence from 50-80% to 10-20%.

Surgical excision (with adjuvant therapy):

CRITICAL: Surgical excision alone has a 50-80% recurrence rate for keloids. Surgery should ALWAYS be combined with post-operative treatment — steroid injections (starting 2-4 weeks after surgery), silicone sheets, pressure therapy, or radiation therapy — to prevent regrowth. With combination therapy, recurrence drops to 10-30%.

Cryotherapy:

Liquid nitrogen applied to the keloid surface or injected intralesionally. Can flatten keloids over multiple sessions. Risk of hypopigmentation is significant in darker skin — must be used cautiously and discussed with the patient beforehand.

Radiation therapy (for recalcitrant keloids):

Low-dose superficial radiation delivered within 24-48 hours after surgical excision. Highly effective at preventing recurrence (success rates 70-90%). Reserved for keloids that have failed multiple other treatments. The radiation dose is low and targeted, with minimal long-term risk for small treatment areas.

5-Fluorouracil (5-FU) injections:

An anti-metabolite injected directly into the keloid, often combined with triamcinolone for enhanced efficacy. Inhibits fibroblast proliferation. Effective for keloids that don't respond adequately to steroids alone.

When to See a Dermatologist

See a dermatologist experienced in keloid management if you have a known history of keloids and are planning any skin procedure (surgery, piercing, tattoo), if a scar appears to be growing beyond the wound borders, if a keloid is painful, itchy, or functionally limiting, or if you want to explore treatment options for existing keloids. Keloid prevention is always easier than treatment — if you're keloid-prone, discuss this with your provider before any procedure that breaks the skin.

Frequently Asked Questions

Can I get ear piercings if I'm prone to keloids?

Ear piercing is a high-risk activity for keloid-prone individuals — earlobe keloids are among the most common type. If you choose to proceed, have the piercing done by a dermatologist who can monitor healing, use pressure earrings immediately if keloid tissue starts to form, and consider starting topical silicone at the piercing site during healing. Some dermatologists advise avoiding piercings entirely in patients with a strong keloid history.

Will steroid injections lighten my skin permanently?

Steroid injections can cause temporary hypopigmentation (lightening) at the injection site, which is more noticeable on darker skin. In most cases, the lightening resolves over 3-12 months as the steroid effect wears off. Using the lowest effective steroid concentration and precise injection technique (into the keloid only, not surrounding skin) minimizes this risk.

Why do my keloids keep coming back after surgery?

Keloid recurrence after excision alone is 50-80% because surgery creates a new wound — and the keloid-forming tendency responds to this new wound with another keloid. This is why surgery must ALWAYS be combined with adjuvant therapy: post-operative steroid injections, radiation, silicone sheets, or pressure therapy. Multi-modal combination approaches reduce recurrence to 10-30%.

Are there any new treatments for keloids?

Research is active in several areas: biologics targeting specific inflammatory pathways, bleomycin injections (showing promising results in some studies), laser-assisted drug delivery (using fractional laser to enhance steroid or 5-FU penetration), and anti-TGF-beta antibodies that target the specific growth factor driving excessive collagen production. While none have replaced the standard combination approach yet, the pipeline is encouraging.
