Doctors are raising concerns about a common household item that may be contributing to persistent red and rashy skin. Laundry pods, celebrated for their convenience in simplifying the task of washing clothes and linens, might be leaving behind irritants on fabrics.
These compact packets contain concentrated cleaning agents, including fragrances, preservatives, surfactants, and brighteners, which can linger on clothing and cause discomfort. According to Dr. Sarah Villafranco, a former emergency medicine physician now specializing in skincare, detergent residue from these pods is an often-overlooked trigger for eczema in both children and adults.
Dermatologists have noted an increase in young patients presenting with recurring rashes, particularly in areas like waistbands, cuffs, and necklines. These patterns often puzzle parents until they reconsider the potential impact of their laundry practices.
One issue with laundry pods is that the dissolvable film surrounding them doesn’t always dissolve completely. This is particularly true in cold water, short wash cycles, or when machines are overstuffed. As a result, residues can remain on clothes.
While these chemicals are designed to clean and refresh fabrics, incomplete rinsing can lead to them being trapped within the fibers. When clothes with such residues are worn, especially by children with sensitive skin, they can lead to itching, redness, and inflammation. This highlights the importance of reevaluating laundry habits to prevent skin irritation.
These chemicals are meant to clean and freshen, but when they don’t rinse away fully, they get trapped in the weave of fabrics. When these chemicals are trapped in fabric and come into contact with a child’s sensitive skin all day, they can cause itching, redness and inflammation.
The concern is that many parents don’t make the connection between laundry detergent and their child’s rash, so the irritation continues unnoticed, making eczema, which affects 31 million Americans, harder to control and treat.
‘It’s a 24-hour exposure cycle, as both clothing and bed linens get washed in the same detergent,’ Villafranca said.

Laundry pods are convenient, but they may not be the best fit for every household, especially those with young children and people with sensitive skin.
In babies and toddlers, the outer layer of skin is thinner and more permeable than adult skin, making it easier for irritating chemical residues to penetrate and disrupt the skin.
People with eczema or sensitive skin have a damaged skin barrier that struggles to retain moisture and block out irritants.
When pod residues like fragrances and strong surfactants get trapped in clothing fibers and sit against the skin during the day, those chemicals can sink in, causing painful flares.
‘The most concerning ingredients are surfactants like sodium lauryl/laureth sulfate and synthetic fragrance,’ Villafranco said.
‘These two ingredients are present in almost all conventional laundry detergents, both pods and regular liquid detergents.’
A 2020 study looked at 65 popular laundry products, including detergents, fabric softeners, dryer sheets and stain removers sold in the US and found that many contain known skin allergens.
The most common culprits were fragrances, which showed up in most products, and preservatives like methylisothiazolinone and benzisothiazolinone. Worryingly, even products labeled ‘baby safe’ or ‘free and gentle’ contained these allergens.

Methylisothiazolinone, for example, was found in 80 percent of baby-safe detergents and 57 percent of free-and-gentle formulas.
And in 2023, a study found that laundry detergents, specifically an ingredient called sodium dodecyl sulfate, can directly damage the skin’s protective barrier.
Swiss researchers applied common household detergents to mouse skin and human skin samples and measured the effects.
After just four hours of exposure, the detergents weakened the skin barrier, allowing more water to escape and making it easier for irritants to get in.
The study also found changes in gene and protein activity related to skin barrier function and inflammation. Even low detergent concentrations caused damage.
The researchers concluded that regular, consistent exposure to laundry detergents could contribute to the development of atopic conditions like eczema, asthma and allergies, and called for more research into long-term effects, especially for people with existing skin problems.
A laundry detergent allergy usually presents as a rash in areas where clothing touches the skin. Watch for redness, swelling, itching, dry or peeling skin, blisters, hives or a burning sensation.
The reaction can happen right away or take a few days to appear. Common hotspots include the armpits, groin, neck and the backs of the knees because clothing traps moisture and detergent residue against those areas.
Dr Sarah Villafranco, an emergency medicine physician-turned-skincare scientist behind Osmia Skincare, told the Daily Mail that laundry detergent pods are one of the most underrecognized triggers for eczema in children
Physicians recommend switching to a fragrance-free, dye-free detergent and skipping pods.
Villafranca said: ‘For parents, the simplest way to rule this in or out is to switch to a truly fragrance-free, sodium lauryl/laureth sulfate-free detergent, use less than recommended, and add an extra rinse cycle.
‘If things improve within a couple of weeks, laundry products were likely contributing. That said, the synthetic scent in clothing from conventional laundry detergents may never wash out completely.’
Measure liquid or powder carefully, run an extra rinse cycle and use warm water when fabric allows. Wash new clothes before wearing them, avoid fabric softeners and try a two-week ‘laundry reset’ to see if the rash improves.
Look for clear labels that say ‘free & clear,’ ‘fragrance-free,’ and ‘dye-free.’
‘Unscented’ can still mean masking fragrances. Shorter ingredient lists are often kinder to skin. If your water is hard, consider a booster or water-softening approach so detergents rinse more cleanly.
‘It’s also worth noting that ‘natural’ or ‘eco’ pods aren’t necessarily safer,’ Villafranco said. ‘Many still contain sodium lauryl/laureth sulfate and synthetic fragrance that can be irritating to sensitive skin, so reading the label is important.’
