Eczema on darker skin: why it can look different

Most pictures of eczema show pink or red patches on light skin. If your child has brown or Black skin, their eczema may look nothing like that, and that can make it harder to spot, harder to judge and easier to underestimate. Here’s how eczema tends to look on darker skin, why the difference matters, and what to ask for at the doctor’s office.

Why doesn’t it always look red?

Eczema is inflammation of the skin. On lighter skin, that inflammation shows up as pink or red. On darker skin, the natural pigment (melanin) changes how it looks.

A 2023 review in Clinical and Experimental Dermatology describes eczema on skin of colour as often looking violet, ashy grey or a darker brown rather than red. The American Academy of Dermatology lists dark brown, purple or greyish areas of skin as a sign of eczema on darker skin tones. The NHS describes eczema as red, white, purple or grey, or lighter or darker than the surrounding skin, depending on skin tone.

So if you’re waiting for your child’s skin to “look red” before taking it seriously, you may be waiting for something that won’t happen.

What else can look different?

Colour isn’t the only difference. Some patterns show up more often on darker skin:

• Small, rough bumps. The American Academy of Dermatology notes that small, rough bumps are more common in darker skin tones. The 2023 review describes a papular (bumpy) type where the bumps cluster around hair follicles, giving the skin a goosebump-like texture.
• Different places on the body. Children with brown or Black skin are more likely than white children to have eczema on the trunk, according to the American Academy of Dermatology. In older children, patches often form on the fronts of the knees, the elbows and the backs of the hands, with bumps that look grey to violet-brown.
• On the face in young children, the academy describes several bumps, with or without redness, and darker areas of skin, rather than the bright red cheeks often pictured.
• Thickened skin. With repeated scratching, skin can become thick and leathery, which the academy notes can turn darker or lighter than the skin around it.

Why is it easy to underestimate?

Doctors often judge how severe eczema is partly by how red it looks. On darker skin, that can mislead.

A 2002 UK study followed children with eczema in London, examining each child up to four times, six months apart. At first glance, Black children seemed no more likely than white children to have severe eczema. But once the researchers adjusted for the fact that redness is harder to see on darker skin, Black children were about six times more likely to have severe eczema. The authors warned that redness can be a misleading measure of severity in Black children, and that severe cases might not be detected and treated properly. It was a small study, but the 2023 review makes the same point: relying on redness to grade severity in skin of colour may underestimate how bad the eczema is, which can lead to delays in diagnosis and to undertreatment.

For you as a parent, that means your description matters as much as what the doctor sees. Itch, lost sleep, thickened skin and how often flares come back all tell the story.

What are the pigment changes after a flare?

After a flare settles, many children with darker skin are left with patches that are darker or lighter than the surrounding skin. This can be upsetting, and the 2023 review notes that for some people these changes can be as bothersome as the eczema itself.

• Darker patches are called post-inflammatory hyperpigmentation: pigment left behind after inflammation. DermNet explains it’s temporary, but it’s more common in darker skin and tends to be more intense and last longer. Sunlight can make these patches darker.
• Lighter patches can also follow inflammation. One common cause in children is pityriasis alba, a mild form of eczema that causes pale, slightly scaly patches, most often on the cheeks, neck and upper arms. DermNet says the colour usually returns to normal within a year, though it can take two or three.

These changes are not scars, and they usually fade. But because every flare can leave new marks, they’re one more reason to treat eczema early and keep it controlled, rather than waiting for it to look “bad enough”.

What can parents do?

• Trust itch over colour. If your child is scratching, rubbing or losing sleep, that’s eczema activity, whatever the skin looks like.
• Keep a photo record. Take pictures in good natural light during flares so your doctor can see what you see, even if the skin has calmed by the appointment.
• Describe it in your own words. Tell your doctor the skin looks “ashy”, “purple”, “bumpy like goosebumps” or “darker than usual”. Those details help.
• Ask directly. “Could this be more severe than it looks because of my child’s skin tone?” is a perfectly reasonable question.
• Stick with the basics. Daily moisturizer, gentle fragrance-free cleansing and any prescribed treatment used as directed are the same for every skin tone.
• Protect from the sun. Sun protection helps keep pigment changes from darkening further.
• Go easy on fixes for the marks. Don’t reach for lightening or “brightening” products on a child’s skin without a doctor’s advice.

When to see a doctor

See your doctor or pharmacist if your child has itchy, dry, bumpy or discoloured patches that keep coming back, if eczema is disturbing sleep, or if it isn’t better after two weeks of good daily care. Go promptly if the skin weeps, crusts, blisters or becomes painful. If you feel your child’s eczema is being underestimated, it’s fair to ask for a second look or a referral to a dermatologist.

Eczema on darker skin is the same condition with a different face. It may look purple, grey or brown instead of red, show up as tiny bumps, and leave light or dark marks as it heals. Knowing that helps you spot it sooner, describe it better and make sure it gets the treatment it deserves.
