If gloves carry a risk, shouldn't I just skip them?

No. Gloves keep water, chemicals and allergens off your skin, and those are major causes of hand eczema. Wear them when the job needs it, for as short a time as the job allows, with cotton liners when you wear them for long.

Can I reuse cotton liners?

Cotton liners can be washed and reused, as long as they are completely dry before you put them on. During the day, swap to a fresh pair as soon as they get damp, so keep several pairs. Single-use waterproof gloves should be used once and thrown away.

Is my hand rash an allergy to the gloves?

It could be irritation from moisture, an allergy to something in the glove, or an allergy to something you handle at work. You can't tell by looking. A dermatologist may arrange patch testing to find the cause.

Long glove wear counts as wet work: hand eczema, cotton liners, seeing a doctor

Waterproof gloves worn for a long time can hurt your hands the way soaking them does. The European Society of Contact Dermatitis (ESCD) 2022 guideline, and reviews citing it, count wearing occlusive gloves for 2 hours or more a day as “wet work”, a leading cause of hand eczema. The fix isn’t to stop wearing gloves. It’s to wear them properly, line them with cotton, and know when to see a doctor.

What counts as wet work

The widely used definition, in research and in reviews citing the ESCD 2022 guideline, has three parts. Meeting any one counts:

Part	Daily threshold
Wet hands	2 hours or more in total
Wearing waterproof (occlusive) gloves	2 hours or more in total
Hand washing	20 times or more

A Danish study from 2020, covering almost 50,000 people, found that after 2 hours a day in gloves, the odds of hand eczema rose to about 3.19 times for women and 1.82 times for men. Risk rose significantly from around 30 minutes a day on average, and the authors suggest the 2-hour threshold may need to come down.

Why gloves that keep water out make hands “wet”

Waterproof gloves don’t let air through, so sweat can’t evaporate and the inside gets hot and damp. Skin that sits in that for long becomes irritated. A 2025 study citing the ESCD guideline sums it up: occlusive gloves themselves cause or worsen hand dermatoses, especially when worn for long periods together with soaps or detergents.

A 2021 trial in 30 people with chronic hand eczema had them wear a vinyl glove on the worse hand for 2 hours, take a 30-minute break, then wear a new glove for 2 more hours. Staphylococcus aureus on the eczema increased significantly, while unaffected skin showed no increase. The authors think this may prolong the disease, and call for more research on wear time and glove liners.

Gloves are essential protection, but every minute in a glove counts as a minute of “wet” hands. Keep it short and line them with cotton.

Gloving over 10 minutes: cotton liner underneath, swapped when damp

How to use cotton liners

The ESCD 2022 guideline and the German guideline from 2023 recommend textile liners whenever occlusive gloves are worn for more than 10 minutes. Cotton can only absorb so much sweat, so it has to be swapped for a dry pair once it is damp or soaked. The American Academy of Dermatology (AAD) gives the same advice for wet work: 100% cotton gloves under waterproof ones.

Wash your hands and dry them completely before gloving (WHO advises hands be fully dry before putting on gloves).
Put the cotton gloves on first, then the waterproof gloves over them.
When the cotton gets damp, change to a fresh pair. Sweat-soaked cotton is like wrapping your hands in a wet cloth.
Take gloves off during breaks so your skin can dry.
Use single-use waterproof gloves once, then throw them away.
If you are gloving against chemicals or nail gel, cotton doesn’t stop chemicals. Choose the outer glove for the job; see Gloves for gel work.

Example: a nail technician’s day, over the line?

Say you wear nitrile gloves in three work blocks and wash your hands during the day.

Morning 50 minutes, afternoon 45 minutes, evening 40 minutes.
Total: 50 + 45 + 40 = 135 minutes = 2 hours 15 minutes. That is over the 2-hour mark, so today counts as wet work, even though your hands never touched water.
Hand washes: 14. Under 20, but it still adds to the load on your skin.
Every block is longer than 10 minutes, so each needs liners. If the cotton needs changing about once per block, you need at least 6 pairs of liners a day (3 pairs to start + 3 mid-block swaps).
Cut soap washes: when your hands aren’t dirty or exposed to chemicals, alcohol rub will do. Why, in Alcohol hand rub is gentler than soap.

Common mistakes

Putting gloves on damp hands. You trap water inside from the start.
One pair for a whole block with no break. Moisture keeps building.
Keeping sweat-damp liners on. Wet cotton against skin is worse than none.
Not counting glove time. Thinking that dry hands mean it isn’t wet work.
Gloving over flaring eczema for hours without asking a doctor how to look after it.

Look after the basics too: fragrance-free hand cream after washing and after taking gloves off, lukewarm rather than hot water, and rings off before washing. More in Hand and skin care basics.

When to see a dermatologist

Hand eczema that lasts more than 3 months, or comes back 2 or more times in a year. The ESCD guideline counts that as chronic hand eczema, which should be investigated.
You’re not sure what you’re reacting to: gloves, cleaning products or things you handle at work. A dermatologist may arrange patch testing.
Cracks that hurt or bleed, blisters, swelling, or a rash spreading beyond the hands.
The rash stops you working.
