A childcare worker who notices recurring redness, cracking, or infected skin on their hands after months of nappy changing, handwashing, and glove use is not simply unlucky. They are experiencing one of the most common and consistently underreported occupational skin conditions in the care sector. The pattern is recognisable: skin that starts out slightly dry, progresses to cracking and soreness, and eventually becomes vulnerable to bacterial or fungal infection on a near-weekly basis. Understanding why this happens, what makes it worse, and what genuinely helps is the first step toward stopping the cycle.

What wet work actually does to the skin barrier

Healthy skin has a lipid-rich outer layer that acts as a physical barrier against microorganisms, irritants, and moisture loss. Wet work — defined in occupational health as having wet or gloved hands for more than two hours per day, or washing hands more than twenty times per shift — degrades this barrier progressively. Water itself, when exposure is prolonged, swells the outer skin cells and then strips natural oils as the skin dries out. Repeated cycles of wetting and drying are more damaging than continuous immersion.

Childcare workers face this cycle constantly. Nappy changing involves direct contact with biological material, followed by handwashing, followed by application of alcohol-based gel, followed by glove use, followed by further handwashing. Each step in that sequence has its own drying or sensitising effect. Soap removes lipids. Alcohol-based gels, used repeatedly on already-dry skin, cause stinging and further lipid loss. Disposable gloves — while essential for infection control — create a warm, moist environment inside the glove that further weakens already-compromised skin. Over a full working day, a childcare worker in a busy nursery may go through this cycle forty to sixty times.

Why infections keep coming back

Once the skin barrier is disrupted, even superficially, pathways open for microorganisms that would not ordinarily penetrate intact skin. The hands of workers in childcare settings carry high loads of both common and resistant bacteria — Staphylococcus aureus, including community-associated strains — as well as fungal organisms such as Candida. Cracked skin around the fingertips and knuckles, nail folds, and between the fingers creates entry points. Small splits that the worker barely notices become infected, clear partially with treatment, and then recur because the underlying skin damage has not been repaired between episodes.

This is why a worker may report that antibiotics or antifungal creams work briefly but the problem keeps coming back. The infection is not the root problem; it is the consequence of structural skin damage driven by occupational exposure. Treating only the infection without addressing the wet work cycle is like patching a leak without turning off the water supply.

Early signs and how they progress if ignored

The early signs of occupational contact dermatitis from wet work are easy to dismiss: mild dryness, a slight tightening feeling after handwashing, occasional itching between the fingers. At this stage, many workers assume they simply have dry skin and apply hand cream sporadically. Without systematic skin protection, these early signs typically progress within weeks to months into visible redness, scaling, and thickened skin on the backs of the hands and fingers. Painful cracks — fissures — develop at the fingertip creases and around the nails. At this stage the skin is bleeding, frequently infected, and interfering with the worker's ability to grip, change nappies, fasten clothing, and carry out fine motor care tasks.

In some workers, repeated exposure to wet work triggers allergic contact dermatitis rather than, or in addition to, the irritant form. Rubber accelerants in latex or nitrile gloves, fragrances in soap, and preservatives in hand creams are all recognised allergens in this occupational group. Allergic reactions tend to be more intense, spread beyond the area of direct contact, and persist even on days off. If a worker notices that their skin reaction is worsening despite switching products, or that it involves swelling and blistering disproportionate to the exposure, allergic sensitisation should be suspected and assessed by an occupational health professional or dermatologist.

What employers are required to do

In most jurisdictions, employers have a legal duty to assess and control occupational skin exposure before it causes harm, not after a worker has already developed a problem. For childcare settings, this means conducting a formal skin assessment as part of routine health and safety management, identifying which tasks involve wet work, estimating the daily duration of exposure, and evaluating whether current control measures are adequate.

Specific employer duties in this setting typically include: providing alcohol-based hand rub as a partial alternative to soap-and-water washing where clinically appropriate, so that the number of soap washes is reduced; supplying appropriate gloves with a known low-allergen profile and replacing them regularly during shifts; providing an emollient-based skin conditioning cream for use before work, during breaks, and at end of shift; and ensuring workers have adequate time to complete handwashing and skin care properly rather than rushing. Pre-placement and periodic skin surveillance — visual checks of workers' hands by a trained person, with referral criteria — should be part of the setting's health monitoring programme.

An employer who provides gloves but no moisturiser, or who supplies a moisturiser but leaves workers without time to apply it, has not met their duty. Control measures only work as a system.

Practical controls, in order of effectiveness

The most effective control is reducing the frequency and duration of skin exposure to water, soap, and biological material. In a childcare setting, complete elimination is not possible, but exposure can be rationalised. Using alcohol-based hand rub instead of soap for routine hand hygiene between nappy changes — where hands are not visibly contaminated — significantly reduces the number of soap washes per shift. Soap should be used when hands are visibly soiled, and the soap selected should be pH-neutral and fragrance-free.

Gloves are the next control, but glove type matters. Nitrile gloves are preferred for most workers because latex carries a higher sensitisation risk. Gloves should fit properly — too tight a fit causes friction and sweat retention; too loose a fit allows biological material to enter at the cuff. Gloves should be changed between nappy changes, not worn continuously for extended periods. Cotton liner gloves worn under nitrile gloves during extended tasks can reduce sweat accumulation and friction, though this is impractical during direct care tasks.

Skin conditioning is not optional at this level of wet work exposure. A fragrance-free, preservative-free emollient applied before the first glove of the day, at every break, and at the end of the shift materially slows barrier degradation. Workers should not use their own choice of moisturiser at random; the employer should select products and make them available at every handwashing station. Thin, water-based lotions have very limited protective effect; barrier creams and thicker emollients are more effective.

Protective gloves for domestic tasks at home — cleaning, dishwashing — should be recommended for affected workers, because home wet work adds to the total exposure burden and prevents recovery of the skin barrier overnight.

What a worker should do if already affected

A childcare worker who has progressed beyond mild dryness to persistent cracking, pain, or repeated infections should not wait to see whether it improves on its own. They should report the problem to their employer or line manager promptly, because early intervention produces faster resolution and reduces the risk of permanent sensitisation. Occupational health services can assess the skin, identify whether the condition is irritant or allergic, and recommend appropriate treatment and work modification.

Where an infection is present, a healthcare provider should assess whether topical or oral treatment is needed. Attempting to self-treat repeated infections with over-the-counter products while continuing unmodified work exposure is unlikely to succeed. The worker may also need short-term modification of tasks — temporarily reducing direct nappy-changing duties while the skin barrier recovers — which the employer should accommodate where possible.

Workers should not use any steroid cream obtained informally or without guidance. Inappropriate steroid use on infected skin, or long-term unsupervised use, carries its own risks. A structured treatment plan from a clinician, combined with improved workplace skin protection, is more effective than either alone.

What people commonly get wrong about this condition

The most common misunderstanding is that frequent handwashing is protective and therefore cannot be the problem. In infection control terms, handwashing is essential. But in occupational dermatology terms, handwashing is also a significant irritant — and the two facts coexist. The solution is not to wash hands less, but to use the mildest effective product, supplement washing with alcohol-based rub where appropriate, and actively restore the skin barrier through moisturisation.

A second misunderstanding is that the problem is personal — a sign that the worker has sensitive skin and should perhaps consider a different career. Occupational contact dermatitis from wet work affects workers across the full range of skin types and is caused by the exposure, not a personal deficiency. With correct controls in place, most workers can continue in childcare without permanent skin damage. The failure to control it is an employer failure, not a worker failure.

Health at Work supports employers in childcare and care settings to design and implement skin protection programmes, conduct periodic skin health surveillance, and manage workers who have already developed occupational skin conditions. Early engagement with occupational health services produces better outcomes than waiting until a problem has become severe and recurring.
