Neonatal skin care for the very preterm infant

Very preterm infants enter the world with skin that is structurally and functionally immature. The epidermal barrier is thin, transepidermal water loss is high, and the skin can be easily damaged by friction, adhesive products, cleansing agents, and repeated handling. Care that seems gentle for a full-term newborn may still cause injury in an infant born at 24 or 26 weeks’ gestation.

A well-designed neonatal skin-care routine protects the barrier while supporting respiratory care, monitoring, nutrition, infection prevention, and family bonding. It should be individualized according to gestational age, postnatal age, skin condition, humidity, clinical stability, and the devices required for treatment.

Perinatal teams can also place these practices within the wider context of neonatal research and education. The FAOPS 2020 archive provides historical access to a congress centered on perinatal and neonatal medicine, scientific programs, and related clinical exchange.

Why immature skin needs special protection

The stratum corneum of an extremely preterm infant contains fewer and less mature cell layers than that of a term newborn. This creates a weak barrier against water loss and environmental irritants. High transepidermal water loss can contribute to dehydration, electrolyte imbalance, heat loss, and increased energy expenditure.

The skin also has limited mechanical strength. Removing a monitoring electrode or dressing may strip the superficial epidermis, especially when the product has strong adhesion or has been left in place for too long. Small injuries can become painful entry points for microorganisms and may complicate the placement of intravenous lines, respiratory interfaces, or feeding equipment.

Skin maturity changes rapidly during the first weeks of life. A very preterm infant may require high humidity in an incubator early on, followed by gradual adjustment as the barrier develops. Nurses and medical staff should document trends rather than treating skin care as a fixed protocol that applies equally throughout hospitalization.

Creating a protective bedside environment

Thermal stability is a central part of neonatal dermatology. An incubator or radiant warmer should be managed according to the infant’s temperature, humidity needs, respiratory condition, and local unit policy. Excessive exposure during procedures increases evaporative and radiant heat loss, so care should be clustered when clinically appropriate and the infant should be covered during short interventions.

Humidity can reduce transepidermal water loss in the earliest days, particularly for infants at the lowest gestational ages. It must be monitored carefully because excessive moisture around the neck, axillae, groin, or skin folds can cause maceration and promote microbial growth. Humidification equipment requires consistent cleaning and maintenance.

The bedside should also reduce unnecessary contact. Warm hands, soft linens, smooth positioning aids, and organized tubing help prevent friction and shear. A developmentally supportive position can protect pressure points while limiting the number of times the infant must be repositioned for routine tasks.

Cleansing, bathing, and emollient use

Routine bathing is usually unnecessary during the first days of life. When cleansing is required, use warm water and a soft, sterile or clean material according to the neonatal unit’s infection-control policy. The process should be brief, with special attention to drying rather than rubbing. Blood, meconium, antiseptic residue, and milk should be removed promptly because prolonged contact can irritate the skin.

Mild, fragrance-free products may be considered when water alone is insufficient, but every cleanser should be evaluated for pH, preservatives, surfactants, and potential toxicity. Adult soaps, perfumed wipes, essential oils, talc, and products containing alcohol should not be used on fragile preterm skin.

Emollients can reduce water loss and support barrier function in selected infants, yet their use should follow local guidance and the infant’s clinical status. A thin layer of a product with a well-established safety profile may be applied to intact, dry skin. Avoid routine application over infected, broken, or heavily occluded areas unless directed by the neonatal team. Product containers should be handled hygienically, and shared jars should be avoided to reduce contamination.

Protecting skin from adhesives and devices

Medical adhesives are among the most common causes of neonatal skin injury. Before applying an electrode, sensor, tube holder, or dressing, clinicians should confirm that the product is essential, select the least aggressive suitable material, and place it on intact skin whenever possible. The smallest effective adhesive area is preferable.

Removal should be slow and parallel to the skin, while supporting the surrounding tissue. A silicone-based adhesive remover may be appropriate in some units, but it should be used only according to product instructions and institutional policy. Pulling upward, removing tape rapidly, or repeatedly repositioning the same device can cause epidermal stripping.

Devices should be checked at every assessment for pressure, moisture, redness, swelling, blistering, and impaired circulation. Pulse oximeter probes and respiratory interfaces require regular site rotation when clinically feasible. Nasal prongs and masks should be positioned to avoid pressure on the septum and nares, with protective dressings used only when they fit safely and do not conceal early tissue damage.

Preventing diaper and moisture-associated dermatitis

The perineal area is exposed to urine, stool, digestive enzymes, friction, and occlusion. Very preterm infants may develop erythema or erosions quickly, especially during antibiotic treatment, diarrhea, or frequent stooling. Prevention begins with prompt diaper changes and gentle cleaning that removes irritants without repeated vigorous wiping.

A thin protective barrier may be applied when the skin is exposed to frequent stool or moisture. The product should be compatible with the unit’s assessment practices and should not make it difficult to observe worsening redness, ulceration, or infection. If a barrier is already present, excessive scrubbing to remove every trace can cause more harm than leaving a clean, thin layer in place.

Persistent rash requires clinical review. Candidal dermatitis, irritant dermatitis, pressure injury, and early bacterial infection may appear similar at first but require different management. Open lesions, spreading redness, unusual drainage, bleeding, or a sudden change in skin appearance should be reported promptly.

Recognizing injury and responding early

A structured skin assessment should occur at admission, during routine care, after procedures, and whenever the infant’s condition changes. Examine the scalp, face, trunk, extremities, skin folds, diaper area, and all sites covered by equipment. Record color, integrity, moisture, temperature, bruising, edema, pressure marks, and the location and size of any lesion.

The Neonatal Skin Condition Score or a comparable validated tool can improve communication between caregivers. Documentation should identify the suspected cause, such as adhesive trauma, pressure, moisture, extravasation, or friction. A photograph may support monitoring when permitted by institutional policy and parental consent procedures.

Management depends on the injury. Remove or reposition the offending device when safe, reduce pressure and moisture, use an appropriate dressing, and obtain medical review for deeper wounds or suspected infection. Extravasation, burns, rapidly spreading erythema, necrosis, and lesions associated with systemic instability require urgent escalation rather than routine observation.

Supporting comfort, bonding, and family participation

Skin care is a sensory experience for a fragile infant. Handling should be slow, predictable, and coordinated with the infant’s behavioral cues. Containment, facilitated tucking, non-nutritive sucking, reduced noise, and appropriate pauses can lower stress during cleansing, dressing changes, and device replacement.

Parents can participate in hand hygiene, gentle containment, diaper care, and skin-to-skin contact when the infant is stable and the clinical team approves. Kangaroo care supports bonding and may help with temperature regulation and physiologic stability, although tubing, lines, and respiratory support must be secured before transfer.

Families should receive clear explanations about why the infant’s skin looks different, why bathing may be delayed, and why some products are avoided. Teaching should include signs that need immediate attention: increasing redness, blisters, bleeding, discharge, a persistent pressure mark, or a change in skin color. Consistent communication helps parents become confident partners in daily neonatal care.

Practical priorities for neonatal teams

Effective practice depends on shared routines, appropriate supplies, and regular review. Every member of the team should know which adhesives, cleansers, emollients, barriers, and dressings are approved for very preterm infants. Products should be selected for safety and necessity rather than convenience.

The following priorities help translate neonatal skin research into bedside care:

• Assess skin systematically and document changes at every relevant care episode.
• Minimize friction, shear, pressure, adhesive exposure, and unnecessary handling.
• Maintain appropriate thermal and humidity conditions while watching for maceration.
• Use gentle cleansing, prompt diaper care, and approved protective products sparingly.
• Involve parents in safe skin-to-skin contact and basic care under staff guidance.

A prevention-focused approach is especially valuable in the first two weeks, when the barrier is most vulnerable. It should then evolve as the infant grows, the skin matures, humidity decreases, and medical devices are removed. Regular review prevents outdated routines from continuing after the infant’s needs have changed.

Safe skin care is a clinical responsibility shared by nurses, neonatologists, respiratory therapists, pharmacists, infection-prevention staff, and families. Apply these principles at the bedside, audit skin-injury patterns in the unit, and use each assessment to refine care for the next very preterm infant.
