At our local clinic, Maya, a 34-year-old schoolteacher, entered on a Tuesday morning with fear on her face. Her hands were badly swollen, the skin red and blistered.
Dr. Priya, I think I’m having an allergic reaction, she said. I can not stop scratching — it began last night and only became worse overnight.”
As I examined her hands gently, I asked her to reflect over the last few days. “Are you using anything new — skin care products, cleaning products, even new jewelry?”
She paused. “Actually… I recently changed the dish soap I was using. It smells like citrus.”
That was the clue we needed. Contact dermatitis.
That was a textbook example of Maya’s story. And I’ve encountered many like hers — construction workers, nurses, chefs and even parents who were exposed through baby wipes. Those rashes aren’t just skin-deep. They bring frustration, lost sleep, humiliation and even time off work.
So let’s dig into what contact dermatitis actually is, how to spot it early, treat it effectively and most importantly, prevent those itchy episodes in the future.
What Is Contact Dermatitis?
Contact dermatitis is an inflammation of the skin that occurs when your skin reacts to something it comes into contact with. It is not contagious, but the pain can be severe.
There are two main types:
Irritant Contact Dermatitis occurs when repeated exposure to these sorts of substances (soap, water, bleach, detergents): breaks down the skin barrier. It’s actually a kind of response I often notice in individuals who wash their hands a lot or do household cleaning without gloves.
Allergic Contact Dermatitis, by contrast, is a bit sneakier. It’s your immune system responding to something to which you’re sensitized, such as nickel in jewelry, fragrances in lotion, latex gloves or ingredients in makeup.
Common triggers and risk factors
In my years of practice, I’ve seen that some of the most innocent-seeming products can end up being the worst offenders.
One baker, for example, comes to mind. He thought he was responding to flour, but it turned out to be the cinnamon in a new hand cream he was applying between baking shifts.
Irritating soaps, detergents, acid-based cleaners, constant exposure to water, even natural plant-based oils can elicit reactions. So are allergens such as nickel, formaldehyde and certain essential oils.
Reactions can also be worsened by dry, cold weather or heat and humidity. And if you have sensitive skin or eczema to begin with, you’re even more susceptible.
Who Is at Risk?
I tend to see contact dermatitis in those who work with their hands: nurses, hairstylists, chefs, gardeners, construction workers and cleaners.
Healthcare workers repeatedly wash their hands and use alcohol-based sanitizers. Strong chemicals are used by cleaners. Plants and pesticides are part of the life of farmers and gardeners. Even artists can be allergic to paints or adhesives.
With awareness of your risk, you can seize control — wear gloves, moisturize regularly, and replace with gentle, fragrance-free products.
Recognizing the Symptoms
Maya’s symptoms were classic: red, itchy skin that swelled and formed tiny, oozing blisters.
Others may see dry scaly patches. On darker skin, the rash may present as darker brown, gray or purple instead of red.
For some patients, I’ve seen the rash appear only hours after exposure. In allergic dermatitis, the symptoms may not appear until a day or two later.
Watch out for:
-
Severe itching
-
Pain or burning sensations
-
Skin that is dry, cracked or leathery
-
Fluid-filled blisters
-
Rashes in areas of direct contact such as hands, face or neck
Diagnosis: Uncovering the Perpetrator
In the case of Maya, the dish soap was an obvious trigger. But it’s not always that easy. That’s where patch testing comes in.
One patient was a florist who was allergic to eucalyptus stems. With patch testing, we were able to identify that it wasn’t the flowers that were the culprits, but the preservatives in the floral foam.
Patch testing: Tiny amounts of suspected allergens are placed on your back to watch how your skin reacts over 48 to 72 hours. It’s useful for diagnosing what’s causing persistent or chronic dermatitis.
Treatment: Relief Begins With Avoidance
Identifying the trigger as the first step in getting rid of it (in this case, the trigger) is to avoid the trigger. For Maya, that meant using a gentle, fragrance-free dishwashing liquid and wearing gloves when doing work in the kitchen.
I prescribed her a topical corticosteroid to help with inflammation, as well as an antihistamine, to help with her itching. We also discussed thick moisturizers, particularly after handwashing.
In more severe or chronic cases, I may use oral corticosteroids or immunosuppressive creams such as tacrolimus. Light therapy (UVB) can also help patients who don’t respond to standard treatments.
Staving Off Flare-Ups: Little Tweaks, Big Deal
Preventing flare-ups in the future begins with your awareness. I always advise my patients:
As such, switch to fragrance-free products. Unscented doesn’t mean that it’s safe—it might still have masking fragrances.
Keep hands moisturized, especially foot washing.
Read labels carefully. Organic doesn’t mean gentle.
Wear gloves when cleaning or gardening.
Do not dismiss initial symptoms — a mild rash can become serious rapidly.
Maya made a list of “safe products” to which she could adhere. She even began wearing gloves when using classroom supplies.
When Things Get Complicated
Most individuals bounce back quickly, but there are red flags to look out for.
If you see severe blisters, have pus or feel fever—get help. These can be symptoms of an infection.
And while rare, I’ve watched extreme allergic reactions produce swelling around the face or throat. That’s a medical emergency and needs to be treated urgently.
Final Thoughts: Give Up Frustration and Follow Empowerment
When Maya came back for her follow-up visit, her hands were almost completely healed. “It was so much stress for me, and I didn’t know it,” she said, smiling.
