Keloid Scars: Why Early Treatment Makes All the Difference
📋 Summary:
Keloids are raised scars that grow beyond the original wound, causing itching and pain. More common in Asian skin, they appear on the chest, shoulders, and earlobes. Unlike hypertrophic scars, keloids don't resolve on their own. Early treatment—steroid injections, laser, or cryotherapy—prevents growth. Never attempt self-removal. Seek medical advice promptly.
A Doctor's Perspective
What Exactly Is a Keloid – and Why Should You Care?
Keloids are firm, raised scars that grow beyond the original wound. They form when your body produces too much collagen during the healing process. They can develop after even minor injuries – a pimple, an ear piercing, an insect bite, or a surgical cut. While keloids aren't dangerous, they can be itchy, painful, or unsightly. And they have a tendency to keep growing over time.
Family physician Dr Ivan Chow explains that keloids are not ordinary scars. They're a sign that your body's healing process has gone into overdrive. That's why they need a proper medical assessment – to confirm the diagnosis and find the safest, most effective treatment for you.
Why You Shouldn't Rely on Self-Diagnosis
Keloids can look a lot like other skin conditions, including:
- Hypertrophic scars
- Dermatofibromas
- Nodular acne scars
- Benign skin tumours
- Skin cancers (rare, but possible)
Because of this overlap, self-diagnosis is risky. Some people try home remedies – scraping, burning, or applying unregulated creams – which often make the scar worse.
Dr. Ivan Chow emphasises:
"Keloids are a medical condition that needs proper attention. The sooner you treat them, the better – you'll prevent the scar from growing larger or becoming more troublesome."
✅ A proper medical check-up will help:
- Confirm the correct diagnosis
- Identify high-risk areas
- Assess symptoms like itching, pain, or tightness
- Recommend safe and appropriate treatment
Understanding Keloid Scars
Keloids form when your skin produces too much collagen during healing. Unlike normal scars, keloids grow beyond the original injury site.
Common Features
- Firm, raised, rubbery texture
- Pink, red, brown, or skin-coloured
- Extends beyond the original wound
- May be itchy or painful
- Continues to grow over months or even years
Common Locations
- Chest
- Shoulders
- Upper back
- Earlobes (especially after piercings)
- Jawline
- Upper arms
Who Is More Likely to Develop Keloids?
- People with darker skin tones (including Asian skin)
- Those aged 10 to 40
- People with a family history of keloids
- Those with acne-prone skin
- Anyone with repeated skin trauma
Keloids are not infectious – they don't spread through contact.
Keloid vs. Hypertrophic Scar – Why the Difference Matters
Many people confuse keloids with hypertrophic scars, but they're not the same:
Hypertrophic Scar
- Raised, but stays within the wound boundary
- Often improves over time
- Responds well to early treatment
Keloid
- Grows beyond the wound boundary
- Continues to enlarge over time
- More resistant to treatment
Getting the right diagnosis is the first step to getting the right treatment.
What Happens If You Ignore a Keloid?
Keloids are benign, but if left untreated, they may:
- Grow larger
- Become thicker and harder
- Cause itching or pain
- Restrict movement if they're near a joint
- Become a cosmetic concern
- Become much harder to treat later on
⚠️ Home removal is dangerous
Some people try to remove keloids at home by:
- Cutting
- Burning
- Using unregulated acids
- Applying herbal pastes
These methods can cause:
- Infection
- Worsening of the keloid
- Larger scars
- Bleeding
- Pigmentation changes
Keloids do not go away on their own.
Medical Treatment Options
Treatment depends on the size, location, symptoms, and your preference. Often, combination therapy gives the best results.
1. Steroid Injections (First-Line Treatment)
Corticosteroids are injected into the keloid to reduce inflammation and flatten the scar.
✅ Benefits:
- Reduces itching and pain
- Softens and flattens the scar
- Minimal downtime
- Safe for most skin types
Usually requires multiple sessions.
2. Cryotherapy (Freezing)
Liquid nitrogen is applied to freeze the keloid.
✅ Benefits:
- Reduces size and hardness
- Useful for small lesions
⚠️ Note:
May cause temporary pigmentation changes in darker skin types.
3. Laser Therapy
Certain lasers can reduce redness and flatten the scar.
Common options:
- Pulsed dye laser (PDL)
- Fractional laser
✅ Benefits:
- Improves texture and colour
- Useful in combination therapy
Laser treatment must be done in a medical setting.
4. Surgical Removal (With Caution)
Surgery can remove the keloid, but alone it carries a high risk of recurrence.
To reduce recurrence, surgery is often combined with:
- Steroid injections
- Pressure therapy
- Silicone gel
- Radiation therapy (in selected cases)
5. Silicone Gel or Silicone Sheets
A non-invasive option.
✅ Benefits:
- Reduces thickness
- Improves texture
- Helps prevent recurrence after treatment
Requires consistent, regular use.
6. Pressure Therapy
Commonly used for earlobe keloids after piercing removal.
✅ Benefits:
- Reduces recurrence
- Useful after surgery
Requires custom pressure earrings or devices.
7. Radiation Therapy (Specialist Use Only)
Used after surgical removal in selected cases.
✅ Benefits:
- Reduces recurrence
- Effective for large or recurrent keloids
Requires specialist referral.
Risks and Considerations
When performed medically, treatment is safe. Potential risks include:
- Temporary redness
- Mild swelling
- Pigmentation changes
- Recurrence (common without combination therapy)
A medical evaluation ensures the safest and most effective approach for you.
Prevention Strategies
Your doctor may advise:
- Avoid unnecessary piercings
- Treat acne early to prevent scarring
- Avoid picking or scratching wounds
- Use silicone gel on fresh surgical wounds
- Seek early treatment for new scars
Insurance Coverage
Insurance often covers:
- Medical consultation
- Steroid injections
- Treatment for symptomatic or painful keloids
- Cases where diagnosis is uncertain
Frequently Asked Questions
Q: Are keloids dangerous?
Dr. Ivan Chow: No. They are benign, but they can grow and cause discomfort.
Q: Can keloids be removed permanently?
Dr. Ivan Chow: Recurrence is possible, but combination therapy significantly reduces the risk.
Q: Do steroid injections hurt?
Dr. Ivan Chow: There may be mild discomfort, but the procedure is quick and well-tolerated.
Q: When should someone seek medical help?
Dr. Ivan Chow: If the scar is growing, painful, itchy, or causing cosmetic concern.
The Bottom Line
Keloids are benign but persistent scars that need proper medical evaluation. Early treatment gives you the best chance of stopping the scar from growing and keeping symptoms under control. Safe and effective treatments – including steroid injections, cryotherapy, laser therapy, silicone gel, and combination therapy – are available in medical settings.
If you notice a scar that keeps growing beyond the original wound, don't wait – seek medical assessment to find out if it's a keloid and discuss your treatment options.
