There is a belief I run into constantly, and it is worth clearing up before anything else: that keloid scars on dark skin are a sign somebody did something wrong. Picked at a spot, chose a careless piercer, did not look after the wound. I have heard it from people who are quietly embarrassed about a raised lump on an earlobe, and it is not true.
What follows is not a treatment guide. Keloids are a medical matter and they belong with a doctor or a dermatologist, and I am going to keep saying that, because it matters more than anything else here. What I can usefully do is explain what a keloid is, why it happens more on melanated skin, and what the people who actually treat them use.
Key takeaways
- A keloid grows out past the edge of the original wound. A hypertrophic scar stays inside it.
- The tendency runs in families — around a third of people who get keloids have a close relative who gets them too.
- They rarely settle on their own, and surgery by itself often brings them back larger.
- Nothing applied to the surface of the skin changes scar tissue. That is a dermatologist’s territory, not a shelf product’s.
What a keloid actually is
A scar is the repair your skin makes after an injury — collagen laid down to close the gap. A keloid is that repair overshooting. The collagen keeps being produced after the wound has closed, and the scar carries on growing. Where it stops is the whole definition. A raised scar that stays within the boundary of the original wound is a hypertrophic scar. One that spreads out past that boundary, onto skin that was never injured, is a keloid.
They tend to be firm, smooth and shiny, and they sit proud of the skin around them. On paler skin they often read as pink or red. On darker skin, as DermNet’s overview of hypertrophic scars and keloids notes, they are less pink and more pigmented — which is one more example of how much skin writing assumes a complexion it is not describing.
They favour particular places. Earlobes after piercing, the shoulders, the chest, the upper back, the upper arms and the cheeks — areas where skin is under tension or moves a lot. Almost any injury can start one, including acne, a burn, a cut, a tattoo or a surgical wound.
Now the part I would rather say too early than too late. Nothing you put on the surface of your skin changes established scar tissue — not an oil, not a butter, not a bark, not anything we make or sell. If you have a raised scar that is growing, painful, itchy or changing, that is a conversation for a GP or a dermatologist, and the sooner the better.
Being straight about that is the only thing that makes the rest of this worth reading. It is the same honesty I try to bring to every skin question people send me, including the one I answered in Is Batana Oil Good for Eczema, where the answer was also less tidy than anybody wanted.

Why keloid scars on dark skin are more common
The short answer is that the tendency is largely inherited. The American Academy of Dermatology’s page on keloid causes puts it plainly: roughly one in three people who develop a keloid has a first-degree relative who also gets them. It is a family trait far more than a personal failing. That inherited tendency is more common in people of African, Asian and Latin-American descent. DermNet records keloids as most prevalent in the deeper Fitzpatrick skin types, with around 16 per cent of Black respondents self-reporting them, and least common in white skin. Those are not small differences.
Why melanated skin specifically is still being worked out. One thread researchers are following is that keloids form more readily on parts of the body with more melanocytes — the cells that make pigment — which is why the chest is a common site and the palm essentially never is. That is an observation about where they appear, not a settled explanation. Age matters too. Keloids most often start between about ten and thirty, with the twenties being the commonest decade, though they can appear at any age. If you got through your twenties without one after piercings and spots, your odds are better than somebody who did not.
None of this means a keloid is inevitable if it runs in your family. It means that if you know you are prone, the decisions worth thinking hardest about are the elective ones — piercings, cosmetic procedures, anything that deliberately breaks the skin in a place keloids like.
Keloid or hypertrophic scar, and how to tell
These two get used interchangeably and they are not the same thing. The distinction matters because they behave differently over time, and because one of them often sorts itself out.
| Feature | Keloid | Hypertrophic scar |
|---|---|---|
| Boundary | Spreads beyond the original wound | Stays within the original wound |
| Over time | Usually persists | May settle on its own |
| Response to treatment | Often resistant, can recur | Generally responds better |
| Common sites | Earlobes, chest, shoulders, upper back | Anywhere skin is under tension |
The practical test is the edge. Look at where the original injury was — the piercing hole, the cut, the spot — and look at where the raised tissue ends. If the lump has climbed onto skin that was never broken, that is the keloid pattern.
Timing is the other clue. Hypertrophic scars usually appear fairly soon after the injury and can flatten over months. Keloids often turn up later, sometimes weeks and sometimes years afterwards, and they tend to keep their shape.
You do not need to diagnose yourself, and I would not try. A dermatologist can usually tell by looking, and will take a small sample only if something about it is unclear. It is a short appointment for a question that otherwise sits in your head for years.
What dermatologists actually do
I want to lay this out neutrally, because people deserve to know what is on the table before they walk in. None of it is a recommendation, and none of it is a decision I am qualified to help you make — that belongs with a doctor or a qualified clinic who can see the scar.
Steroid injections into the scar are the usual starting point, typically repeated every six to eight weeks. Silicone in sheet or gel form is widely used, as are pressure dressings and, for earlobes, pressure earrings. Cryotherapy — controlled freezing — and laser treatment both appear on the NHS page on keloid scars.
Surgery on its own is generally not recommended, because cutting a keloid out is another injury and it frequently returns bigger than before. Where excision is used it is usually paired with something else, such as radiotherapy given very soon afterwards, precisely to head that off.
The honest headline from the NHS is that you cannot get rid of a keloid scar, though treatment can improve how it looks and ease itching or discomfort. The AAD’s guidance on keloid diagnosis and treatment makes a related point — dermatologists often combine two or more approaches, because single treatments frequently are not enough.
One thing worth raising in the appointment if you have deeper skin: any procedure that injures the skin can itself leave a mark on melanated skin, and that includes freezing and lasers. It is not a reason to avoid treatment. It is a reason to ask the clinic directly what their experience is with skin like yours, and to be wary of anyone who waves the question away.
Early is better across all of it. Treatment started while a scar is still forming has a better chance of stopping it growing than treatment started years later.
Frequently asked questions
Why do keloids form more often on darker skin?
Mostly inheritance. The tendency runs in families and is more common in people of African, Asian and Latin-American descent, with about a third of people who get keloids having a close relative who does too. Researchers are also looking at why they appear more readily on areas of the body with more pigment-producing cells, such as the chest. The full explanation is not settled yet.
What is the difference between a keloid and a hypertrophic scar?
The edge of the original wound. A hypertrophic scar is raised but stays inside the boundary of the injury, and it may flatten over months on its own. A keloid grows out past that boundary onto skin that was never damaged, tends to persist, and is more likely to come back after treatment. Both are raised; only one spreads.
Can keloid scars be removed completely?
The NHS puts it bluntly: you cannot get rid of a keloid scar. Treatment can improve how it looks and ease itching or soreness, and starting early can stop one growing further. Surgery alone is usually avoided because removing a keloid is another wound and it often returns larger. Anyone promising complete removal is overselling it.
Do keloids go away on their own?
Generally not. Hypertrophic scars often do settle over time, which is part of why the distinction is worth knowing, but keloids usually persist without treatment. They can also appear a long time after the original injury — sometimes years — so a wound that healed neatly is not a guarantee. If one is changing, that is worth showing a doctor.
Can you prevent keloids from forming after a piercing?
If keloids run in your family, the earlobe is one of the commonest sites, so it is worth weighing up before booking rather than after. There is no reliable home method, and this is squarely a question for a doctor or dermatologist who knows your history. They can tell you what, if anything, is worth doing around an elective piercing.
If you take one thing from this, let it be the edge test and the appointment. Keloid scars on dark skin are common, they are largely inherited, and they are nobody’s fault — and the single most useful thing you can do about one is have somebody qualified look at it early rather than late. Everything else, including everything on my shelves, is ordinary skin care doing an ordinary job.
