So THAT's What Those Tiny Non-Itchy Bumps On Your Arm Are

A couple of years ago, I noticed tiny, flesh-coloured bumps on my fingers that itched like nobody’s business. 

These, I have since learned, are pompholyx or dyshidrotic eczema – a condition which can be so profoundly irritating, it has almost led me to bite my hand.

There’s no cure as yet for dishydrotic eczema, though there are steps you can take to control the symptoms (like using emollient soaps and moisturisers). 

But what about the non-itchy little bumps I’ve had on my upper arms since I was about 17? 

As it turns out, these are keratosis pilaris. 

What is keratosis pilaris?

Keratosis pilaris, or small clusters of bumps (sometimes darker than your skin tone, sometimes not), often appear on your upper arms, thighs, and bum. 

They can affect people of all ages, though the Mayo Clinic says they usually disappear by age 30.

The bumps are harmless and rarely itchy. They are caused by a buildup of keratin in your hair follicles.

This buildup blocks the hair from exiting your skin, leading to bumps and rough, textured skin. The bumps can appear red on pale skin, darker brown on deeper skin tones, or be the same colour as the rest of your skin.

Dry skin can make it worse, and it appears to run in families.

You cannot spread it, but as the NHS warns, “Most people with keratosis pilaris have it for years.” 

It sometimes goes away by itself, the health service adds. The bumps may be worse in summer and better in winter. 

See a pharmacist if you have concerns about keratosis pilaris – partly because they’ll be able to suggest ways to help the affected skin, but also to make sure that you’ve

How can I get rid of keratosis pilaris?

One unsatisfying answer is to simply wait ― the condition usually goes away eventually. 

But you can improve the appearance of your skin in the meantime, the NHS says. 

Some ways to do this include: 

• Moisturising your skin (speak to a pharmacist about your best options)

• Using mild, unscented soaps and shower/bath products 

• Gently scrubbing affected skin with a washcloth or exfoliating mitt

• Avoiding hot showers or baths and opting for cool or lukewarm ones instead

• Avoiding harsh scrubs (though tempting, these can make the condition worse) 
• Trying your best not to scratch, rub, or pick at the bumps. 

Laser treatments and steroid creams can also help, but these are not usually available on the NHS.

Visit a pharmacist if the condition is bothering you or becomes itchy and inflamed. Speak to your GP if you notice any changes to your skin that are unusual for you.
