A keloid is the scar that doesn’t know when to stop. Long after a wound has healed, it keeps growing — raised, firm, often itchy or tender — spreading beyond the original cut into healthy skin. For many people in Dubai, the most frustrating part isn’t the scar itself. It’s that they had it removed once, sometimes twice, and it came back larger than before.
That recurrence is not bad luck, and it is not a sign that nothing can be done. It is the predictable result of treating a keloid like an ordinary scar. With the right, evidence-based approach, keloids can be controlled — and the chance of recurrence brought down dramatically.
What a keloid actually is (and how it differs from a normal scar)
Every scar is the body’s repair response to injury. Normally, collagen is laid down to close a wound and then production switches off. In a keloid, that “off” signal fails: the scar-forming cells keep producing collagen, and the tissue overgrows.
Two features set a keloid apart:
- It grows beyond the original wound. A keloid invades surrounding healthy skin. This is the key difference from a hypertrophic scar, which stays within the boundaries of the original injury.
- It rarely settles on its own. Hypertrophic scars often flatten over months to years. True keloids tend to persist and can keep enlarging.
Keloids can follow any breach of the skin — surgery, ear piercing, acne, a burn, a vaccination, even a minor scratch. They appear most often on the earlobes, chest, shoulders, upper back and jawline.
Why keloids are so common in Dubai
Dubai is one of the most ethnically diverse cities in the world, and keloids are strongly linked to skin type and genetics. People with richly pigmented skin are far more prone to them. Published studies report keloids in roughly 4–16% of some darker-skinned populations, compared with well under 1% in lighter-skinned groups — and the risk for people of African ancestry is estimated to be around 20 times higher than for those of European ancestry.
Family history matters too. About one in three people who develop keloids has a close blood relative who also gets them, and large 2025 genetic studies have identified specific inherited risk variants across African, East Asian and other ancestries. In other words, a keloid is rarely your fault — it is largely written into how your skin heals.
For a city home to large Arab, South Asian, African and Southeast Asian communities, this makes keloids a genuinely common concern, and an important one to treat correctly the first time. That starts with a personalised plan rather than a one-size-fits-all removal — the foundation of proper scar care.
Why simply “cutting it out” usually makes a keloid worse
It seems logical: if the scar is the problem, remove the scar. But surgery creates a new wound — and in someone whose skin forms keloids, that fresh wound can heal into an even larger keloid.
The numbers make the point. When a keloid is excised surgically with no other treatment, it returns in roughly 50–80% of cases, frequently bigger than the original. This is the single most important fact for any patient to understand, and the reason a serious keloid should never be treated by excision alone.
The answer is not to avoid surgery. It is to combine it with a treatment that stops the scar from over-forming again.
The evidence-based approach: surgery combined with radiotherapy
For larger or recurrent keloids, the most effective strategy supported by current evidence is surgical removal followed promptly by a short course of low-dose, superficial radiotherapy. The radiotherapy calms the over-active scar-forming cells in the treated area during the critical early healing window, before a new keloid can take hold.
The results in the medical literature are compelling. A 2025 systematic review of more than 100 studies and over 10,000 keloids confirmed that adding radiotherapy after excision significantly lowers recurrence compared with surgery alone — bringing return rates down from that 50–80% range to roughly 8–20%, depending on the technique and how the wound is closed.
A few points patients most often ask about:
- Timing matters. Radiotherapy works best when it begins within about 24 hours of surgery, which is why the two are planned as one coordinated pathway, not two separate events.
- The dose is low and targeted. This is not the high-dose radiotherapy used to treat cancer. It is a carefully calculated, superficial dose aimed only at the scar site.
- It is a short course. The radiotherapy is typically delivered over just a few days after surgery.
This is precisely the protocol many patients describe after treatment at Atelier Clinic — surgical removal of the keloid followed by a few days of radiotherapy — and it reflects an international standard of care for difficult keloids.
When surgery isn’t the starting point: non-surgical options
Not every keloid needs an operation. For smaller, newer or thinner lesions, a stepwise medical approach is often tried first, and several treatments can be combined:
- Silicone gel or sheeting — the best-evidenced first step for early and developing scars.
- Intralesional injections — corticosteroid (triamcinolone), often combined with 5-fluorouracil, to flatten and soften the scar and relieve itch.
- Cryotherapy — useful for thinner lesions.
- Lasers — to improve redness, thickness and texture.
- Pressure therapy — particularly effective for earlobe keloids after removal.
The skill lies in choosing the right combination for the specific scar, its location and the patient’s skin, and knowing when to escalate to the surgery-plus-radiotherapy pathway.
A holistic, German-precision approach in Dubai
Keloid treatment is one of those areas where experience genuinely changes the outcome. Prof. Dr. Robert Hierner brings German double board certification, more than 35 years of practice and over 10,000 procedures to exactly these complex, recurrent cases — the keloids that have already failed simpler treatment elsewhere.
The approach is deliberately holistic. Every keloid is assessed individually: its size, site, history and the patient’s skin biology. Surgery, when needed, is planned hand-in-hand with radiotherapy and a structured aftercare plan, and supported where appropriate by regenerative medicine and scar-rehabilitation techniques to optimise the quality of the healing skin. The goal is not just to remove a scar, but to give it the best possible chance of never coming back.
Frequently asked questions
Will my keloid definitely come back?
No treatment can promise a zero recurrence rate, but the right combination — most often surgery plus early radiotherapy for larger keloids — reduces recurrence dramatically compared with removal alone. A personalised assessment is the only way to estimate your individual risk.
Is the radiotherapy safe?
The radiotherapy used for keloids is low-dose and superficial, targeted only at the scar. It is a well-established, carefully dosed treatment, and your suitability is reviewed individually before it is recommended.
Does keloid removal hurt?
Surgery is performed under local or general anaesthesia depending on the size and site, so the procedure itself is not painful. Injections and aftercare are managed to keep any discomfort to a minimum.
How long does treatment take?
It depends on the approach. Non-surgical treatment is delivered over a series of sessions; the surgery-plus-radiotherapy pathway typically involves the operation followed by a short course of radiotherapy over a few days, then planned follow-up.
Book a keloid assessment in Dubai
If you have a keloid — especially one that has returned after previous treatment — the most valuable first step is an expert assessment of why, and a plan built around your skin. Book a consultation with Prof. Dr. Robert Hierner to discuss the safest, most effective option for your scar.
