Your Laundry Routine Could Be Affecting Your Skin

Your skincare routine might not be the only thing affecting your skin every day. Your laundry routine could be part of the picture, too.

Think about how much fabric touches your body. Your underwear, shirts, pajamas, towels, pillowcases, and bedsheets can all sit against your skin for hours at a time. Your clothes may touch your skin from the moment you get dressed in the morning until you change at night. Your sheets can stay against your body for seven or eight hours while you sleep.

And every one of those fabrics has been washed with something.

That means your skin isn’t only exposed to the products you intentionally apply to it. It also exists in an environment created by the products used to wash the things touching your body.

For most people, this may never become a problem. But if your skin is already dry, sensitive, or prone to irritation, your laundry routine may be worth examining.

Not because laundry detergent is secretly destroying everyone’s skin. The research simply suggests that, for some people, what remains on clothing after washing may be one piece of a much bigger skin-barrier puzzle.

“Your skin doesn’t know that something wasn’t purchased in the skincare aisle. It experiences its environment as exposure.”

What Does Your Laundry Have to Do With Your Skin?

When you wash your clothes, detergent is designed to remove oils, dirt, sweat, and other substances from fabric. But the washing process doesn’t necessarily mean that every ingredient disappears completely.

The amount of residue left behind can depend on the detergent, the amount used, the washing machine, the size of the load, the rinse cycle, and the fabric itself. That doesn’t automatically make residue dangerous. But skin is constantly interacting with its surroundings. If something is irritating to your particular skin, repeated contact may matter more than a single exposure.

And this is where the research gets interesting. A study published in Acta Dermato-Venereologica examined 148 Japanese patients with atopic dermatitis during winter. Researchers found that 115 participants had widespread or localized dry skin on the trunk. The participants then switched from a common detergent containing more additives to a nonionic detergent with fewer additives for two weeks. Of those 115 people with dry skin, 87, or 76%, experienced moderate or marked improvement after the detergent change.

The researchers concluded that detergent residue remaining in cotton underwear could play a role in the winter deterioration of dry skin in people with atopic dermatitis. That doesn’t prove that detergent residue causes dry skin in everyone. It does, however, give us a reason to consider laundry products when someone is struggling with persistent dryness.

Your Skin Has a Barrier. It Matters.

To understand why this could matter, you have to understand the skin barrier. The outermost part of your skin helps keep water inside while helping protect you from things in your environment. You can think of it as a kind of protective wall.

When that barrier is functioning well, your skin is better able to retain moisture and protect itself. When it becomes compromised, water can escape more easily, and the skin may become dry, rough, irritated, or more reactive. Researchers often measure this process using something called transepidermal water loss, or TEWL.

This is important because a 2023 study investigated the effects of household laundry detergents on mouse skin and ex vivo human skin models. Researchers found that detergent-treated skin showed increased TEWL and reduced electrical impedance compared with untreated skin. They also observed changes in genes and proteins associated with barrier integrity and inflammatory responses.

Now, pause here. That study does not mean that wearing a freshly washed T-shirt will automatically damage your skin. The research involved experimental models, including mouse skin and human skin outside the body. That’s very different from demonstrating that normal laundry habits cause skin disease in humans. But it does demonstrate something scientifically useful: certain detergent exposures can affect biological measures associated with skin-barrier function under experimental conditions. That makes the question worth investigating, not panicking about.

Detergent Isn’t the Only Thing in Your Laundry Room

When people hear “laundry products,” they usually think about detergent. But your laundry routine can involve several different products: laundry detergent, fabric softener, dryer sheets, scent boosters, stain removers, whitening products, fragrance beads, specialty detergents, and fabric sprays.

Every additional product introduces additional ingredients. Some products contain fragrances. Others contain preservatives, surfactants, dyes, enzymes, or other additives. Again, the presence of an ingredient doesn’t automatically mean the ingredient is harmful. The question is exposure.

A study published in Dermatitis examined 65 popular textile-care products sold in the United States, including detergents, fabric softeners, dryer sheets, and stain removers. Researchers identified multiple ingredients recognized as potential contact allergens. Fragrances and essential oils were among the most frequently identified potential allergens across the product categories they examined.

Another study examining household detergents found that fragrance allergens such as limonene and linalool were common ingredients across the products evaluated. Researchers concluded that detergents can contribute to consumer exposure to fragrance allergens and should not be overlooked when assessing potential sources of exposure.

This doesn’t mean you need to throw every scented product in your house into the trash. It means that if your skin is repeatedly irritated and you’re trying to figure out why, your laundry products belong on the list of possibilities.

But Is It Actually an Allergy?

This is where skincare conversations often go sideways. Someone develops an itchy rash and says, “I’m allergic to my detergent.” Maybe. But not necessarily.

There is a difference between irritation and allergic contact dermatitis. An allergy involves an immune response to a substance to which a person has become sensitized. Irritation can happen without an allergic reaction. And research suggests that true laundry-detergent allergy is relatively uncommon.

A review published in 2023 specifically examined whether laundry detergent is a common cause of allergic contact dermatitis. The authors noted that although patients and healthcare providers frequently suspect laundry detergent, available evidence suggests the prevalence of laundry-detergent-associated allergic contact dermatitis may be quite low.

That distinction matters. It would be irresponsible to take studies showing that laundry products contain potential allergens and conclude that everyone wearing freshly washed clothes is being exposed to enough of those substances to develop dermatitis. Exposure, concentration, formulation, washing conditions, and individual sensitivity all matter.

In fact, research examining methylisothiazolinone, a preservative associated with contact allergy, found that it could not be detected in clothing washed under normal household machine-washing conditions, even when the detergent formulations contained the preservative. So the science is more complicated than “detergent residue equals bad skin.” And honestly, that’s a much more interesting story.

What About Fragrance?

Fragrance deserves special attention because it is one of the easiest laundry variables to overlook. We have been trained to associate a strong scent with cleanliness. Fresh laundry is supposed to smell like flowers, ocean air, lavender, vanilla, spring rain, or whatever fictional paradise the detergent company has invented this quarter.

But scent isn’t the same thing as cleanliness. A fragrance primarily changes how something smells. It doesn’t necessarily make your clothes cleaner. And fragrance ingredients can be relevant to contact allergy. A recent review of fragrance contact allergy notes that fragrance materials are widely used and that many can act as contact sensitizers. This is why fragrance can be a useful variable to eliminate when you’re troubleshooting irritated skin.

That doesn’t mean fragrance is inherently bad. Some people can use fragranced products every day without any problem. Others may find that reducing fragrance exposure makes their skin more comfortable. Your skin gets a vote.

And Then There Is Fabric Softener

Fabric softener is another product worth examining. Its purpose is to change the feel of fabric, often by depositing conditioning ingredients onto the fibers. For someone with completely comfortable skin, that may not matter. But if you’re trying to simplify your laundry routine because your skin is irritated, adding another product designed to remain on the fabric may not be necessary. The same applies to dryer sheets and scent boosters.

None of these products should automatically be labeled harmful. They’re simply optional variables. And when you’re trying to figure out why your skin is unhappy, eliminating unnecessary variables can make the investigation easier.

You Might Be Using Too Much Detergent

More detergent doesn’t necessarily mean cleaner clothes. This is one of those wonderfully human habits where “more” feels like it should equal “better,” even when chemistry has not agreed to participate.

Using more detergent than the manufacturer recommends can potentially make rinsing more difficult, especially if the washing machine is overloaded. Your washing machine needs enough room for water and detergent to circulate through the clothing. If the drum is packed completely full, clothes have less room to move. That can affect washing and rinsing performance.

So before assuming you need a stronger detergent, consider whether you’re simply using too much. Follow the dosing instructions for your particular machine and detergent. And don’t eyeball it if you can avoid it. That little measuring cap exists for a reason.

Your Washing Machine Matters Too

The same detergent can behave differently depending on how you wash your clothes. A high-efficiency washing machine uses less water than many older machines. That makes proper detergent dosing especially important. Overloading the machine can also interfere with effective washing and rinsing.

An extra rinse may be useful for someone experimenting with whether detergent residue is contributing to irritation, particularly if the person’s machine and laundry routine allow for it. But again, an extra rinse isn’t a medical treatment. It’s simply one way to reduce a potential exposure while you’re trying to identify whether your laundry routine is relevant.

Don’t Forget Your Towels and Bedding

Here’s the part many people overlook. You may carefully choose a gentle body wash and moisturizer, then wash your towel in heavily fragranced detergent, coat it with fabric softener, and press it directly against your skin. Your pillowcase can be doing the same thing to your face for hours. Your sheets can be doing it to the rest of your body all night.

That doesn’t mean your pillowcase is plotting against you. It means contact matters. If you’re trying to simplify your laundry routine because of skin irritation, consider simplifying the products used on the fabrics that spend the most time against your body. That includes underwear, pajamas, towels, pillowcases, and bedding.

Try a Laundry Reset

You don’t need to replace your entire laundry room. Instead, think of this as an experiment.

Choose a fragrance-free detergent with a relatively simple formulation. Stop using scent boosters for the experiment. Skip fabric softener and dryer sheets temporarily if they’re part of your routine. Use the recommended amount of detergent rather than adding extra. Don’t overload the washing machine. If appropriate for your machine, consider an additional rinse. Then keep everything else about your skincare routine relatively consistent.

That’s important. If you change your detergent, body wash, moisturizer, shampoo, conditioner, sheets, towels, and deodorant at the same time, you may notice an improvement, but you won’t know which change mattered. Changing one major variable at a time gives you better information.

Pay Attention to the Pattern

Your skin can sometimes give you clues about whether your environment is contributing to irritation. Notice where the problem occurs. Does irritation appear underneath clothing? Is it worse around areas where fabric rubs? Does your skin feel particularly dry after sleeping? Are your shoulders, back, waist, neck, or underarms more irritated? Does your skin improve after switching laundry products?

These observations aren’t enough to diagnose a skin condition. But they can help you identify patterns worth discussing with a dermatologist. And if you have persistent itching, a significant rash, cracking, swelling, pain, or worsening eczema, don’t spend months blaming your detergent. Get it evaluated. There are many causes of irritated skin, including eczema, contact dermatitis, environmental dryness, sweat, friction, cleansers, medications, and other conditions. Laundry is one possible piece of the puzzle. It isn’t the entire puzzle.

The Bigger Skincare Lesson

This is what I think gets lost in most skincare conversations. We tend to think of skincare as the products we intentionally put on our bodies: cleanser, serum, moisturizer, sunscreen, maybe an exfoliant if we’re feeling ambitious.

But your skin doesn’t know that something wasn’t purchased in the skincare aisle. It experiences its environment as exposure. The fabric touching your body matters. The water you bathe in matters. The temperature of that water matters. The products you use to clean yourself matter. The products used to clean your clothes can matter, too.

That doesn’t mean you need to live in fear of every ingredient printed on a bottle. It means your skin is responding to an entire environment, not just the moisturizer sitting on your bathroom counter. And that’s why your laundry routine is worth considering when your skincare routine isn’t solving the problem.

So, Is Your Laundry Causing Your Skin Problems?

Maybe. But the more accurate answer is: it could be contributing.

Research has shown that detergent exposure can affect skin-barrier measurements in experimental models. Research has also found improvement in dry skin among people with atopic dermatitis after switching to an additive-reduced detergent. At the same time, studies suggest that true allergic contact dermatitis caused by laundry detergent is uncommon, and the presence of a potential allergen in a laundry product doesn’t automatically mean that normal washing creates a clinically significant exposure.

That’s why the smartest approach isn’t fear. It’s observation. If your skin is comfortable, you may not need to change anything. But if you’re constantly moisturizing and your skin still feels dry, tight, itchy, or irritated, take a look beyond the products you’re deliberately applying.

Look at what touches your skin all day. Look at what touches it all night. Look at what you’re washing those things with. Simplify where you can. Change one variable at a time. And give your skin enough time to tell you whether the change mattered.

Sometimes the problem isn’t what you’re putting on your skin. It’s what you’re leaving behind on everything touching it. Because skincare doesn’t end when you close the bathroom cabinet. Sometimes, it starts in the laundry room.
