10 NICU Skin-Care Principles That Matter at the Bedside

Neonatal skin care can look deceptively simple.

We bathe babies. We change diapers. We apply barriers. We secure devices. We prep the skin before procedures. We remove adhesives. We assess wounds.

But in the NICU, every one of those routine actions happens on skin that may be thinner, more permeable, and far more fragile than the skin of an older child or adult.

That is especially true for premature and extremely low birth weight infants.

Skin care is connected to thermoregulation, infection prevention, pain, fluid balance, developmental care, device safety, and family participation. A product that is appropriate for one baby may be completely inappropriate for another. A cleansing technique that seems harmless can create friction and injury. A dressing that protects a line can also damage the skin underneath it.

And one of the most important lessons is this:

Good neonatal skin care is rarely about finding the “best” product. It is about knowing what you are trying to accomplish and choosing the safest way to accomplish it.

After several weeks of focusing on neonatal skin care, these are the 10 principles I think matter most at the bedside.

1. Protect the skin barrier from day one

Premature skin has very little margin for error.

The more premature the infant, the less mature the stratum corneum and the greater the risk of transepidermal water loss, heat loss, irritation, and injury. Topical products may also be absorbed more readily through immature skin.

For an extremely premature infant, protecting the skin barrier begins immediately.

That means thinking about much more than whether the skin is technically “intact.”

Every adhesive matters.

Every wipe matters.

Every device touching the skin matters.

Every time we expose the baby, reposition them, cleanse the skin, or prepare for a procedure, we have an opportunity either to protect the barrier or add another source of stress.

Humidity, temperature management, gentle handling, careful adhesive use, and minimizing unnecessary friction are all part of skin care.

The goal is not to avoid touching the skin. The goal is to make every interaction intentional.

2. More bathing is not always better

Bathing is one of the clearest examples of why neonatal care should not become task-driven.

A bath may be listed as due, but that does not automatically mean a traditional bath is the right intervention for that baby today.

Before bathing, consider:

• Gestational age

• Postnatal age

• Skin maturity

• Use of humidity

• Temperature stability

• Respiratory and physiologic stability

• Number of devices in place

• How much handling and stimulation the infant can tolerate

For some extremely premature or ELBW infants, a gentle wipe-down with sterile water may be more appropriate than a traditional bath while the skin barrier continues to mature.

This does not mean cleansing has no value.

A bath or modified wipe-down can provide a wonderful opportunity for parents to participate in caregiving. It can also allow the nurse to perform a more complete skin assessment, look behind the ears and under the neck, assess skin folds, check beneath devices, and remove dried blood, stool, adhesive residue, or procedural debris.

Bathing should have a purpose.

The question is not simply, “Is the bath due?”

The better question is:

What type of cleansing does this baby need today?

3. Know what every product is actually for

The number of products used on neonatal skin can become overwhelming.

The easiest way to simplify the decision is to stop thinking first about brand names and start thinking about product categories.

Ask:

What am I trying to accomplish?

A routine cleanser is intended to remove visible soil during bathing.

A moisturizer or emollient is intended to reduce dryness and support the skin barrier.

A moisture barrier, such as Critic-Aid or another institution-approved barrier product, is designed to protect the skin from urine, stool, moisture, and friction.

A wound cleanser, such as a hypochlorous-acid product like Vashe, is intended to cleanse damaged or open skin.

An antiseptic bathing product is used to reduce skin organisms in a specifically approved population.

A procedural antiseptic, such as chlorhexidine or povidone-iodine, is used to prepare the skin before an invasive procedure.

These products may all sit in the same supply room, but they do not do the same job.

A wound cleanser is not automatically a better bath product.

A moisture barrier is not a moisturizer.

A routine baby wash is not an antiseptic.

And a product that is safe for intact skin may not be appropriate for damaged skin.

Understanding the purpose of the product makes almost every skin-care decision easier.

4. Use the least traumatic cleansing method possible

Sometimes the problem is not what we put on neonatal skin.

It is how aggressively we try to remove it.

Repeated wiping creates friction. Friction can damage an already immature barrier. This becomes especially important in the diaper area, around adhesives, and anywhere the skin is already irritated.

Gentle cleansing usually means:

• Dabbing rather than scrubbing

• Using only the amount of pressure needed to remove visible soil

• Avoiding repeated passes over the same area

• Allowing products designed to remain on the skin to remain there

• Using approved adhesive-removal techniques rather than pulling quickly

• Avoiding unnecessary cleansing simply because the skin does not look completely “clean”

There is a difference between removing contamination and trying to make the skin look product-free.

The goal should always be clean enough while causing the least possible trauma.

5. Do not scrub off all the barrier cream

This is one of the simplest bedside changes that can make a big difference.

Barrier cream is meant to stay on the skin.

When a baby stools, especially if they are stooling frequently, the goal is to remove the stool and the visibly contaminated outer layer of product while preserving the clean barrier underneath when appropriate.

Repeatedly scrubbing the skin until every trace of cream is gone creates friction and removes the protection just before the next exposure to stool or urine.

Then we apply more barrier.

Then we scrub it off again a few hours later.

That cycle can become part of the problem.

Instead, gently lift or dab away stool, restore the barrier where coverage is missing, and follow a consistent plan.

For babies with increasing irritation, the type of barrier may need to change. Some infants may benefit from a clear moisture barrier, while others may need a thicker zinc-based paste or another approved product.

The exact product matters less than having a clear plan that everyone follows.

If every nurse uses something different, applies it differently, or removes it differently, it becomes difficult to know whether the skin is actually improving.

6. If a device touches the skin, look underneath it

NICU babies are surrounded by equipment.

Respiratory interfaces, temperature probes, ECG leads, splints, diapers, line dressings, securement devices, feeding tubes, identification bands, tubing, and positioning devices can all create pressure, moisture, friction, or adhesive-related injury.

The difficult part is that the skin injury may develop where we cannot easily see it.

The monitor can look perfect while the skin underneath the device is becoming increasingly compromised.

A good skin assessment therefore cannot only include the areas that are immediately visible.

Look:

• Behind the ears

• Under the neck

• In the axillae

• Within the groin and other skin folds

• Beneath respiratory interfaces

• Around the edges of adhesive dressings

• Under splints and securement devices

• Along tubing that rests against the infant

• Beneath the baby when repositioning

• Around old adhesive or IV sites

This assessment does not necessarily have to happen all at once.

For a fragile infant, it may be safer to complete the full assessment over several care opportunities rather than disturb a stable baby just to check a box.

The important part is knowing what you have not yet seen and making a plan to see it.

7. Your chlorhexidine policy should be easy to understand

Chlorhexidine is an important infection-prevention tool, but neonatal use requires careful thought.

The question should never simply be:

“Do we use CHG in our NICU?”

The better questions are:

• Which infants are eligible?

• Is eligibility based on gestational age, postnatal age, weight, or a combination?

• Is the skin intact?

• What concentration and formulation are being used?

• Is the CHG being used for bathing or for procedural skin preparation?

• Where on the body can it be used?

• What areas should be avoided?

• Does it need to be removed afterward?

• How will pooling be prevented?

This is one area where a clear unit policy can make bedside practice significantly safer.

Nurses should not have to independently interpret the literature every time a line needs to be placed.

A well-designed policy should clearly tell the team when chlorhexidine is appropriate and when another antiseptic, such as povidone-iodine, should be considered.

The exact thresholds may differ between organizations.

What should not differ is the need for a clear, evidence-informed, interdisciplinary plan.

8. Prevent pooling during procedural skin preparation

One of the biggest risks with procedural antiseptics is not necessarily the product itself.

It is prolonged exposure.

Antiseptic solution can run underneath the infant, become trapped beneath linens or drapes, collect in skin folds, or remain against the skin beneath a device.

For very premature infants, that prolonged exposure can contribute to significant skin injury.

When preparing neonatal skin for an invasive procedure:

Use only the amount needed to cover the intended area.

Pay attention to where excess solution is going.

Do not allow saturated materials to remain underneath the infant.

Be particularly careful in the neck, axillae, groin, and other areas where fluid can collect.

Follow the manufacturer's instructions and your unit policy regarding drying, removal, or rinsing.

And reassess the skin afterward.

Procedural antisepsis should reduce infection risk without creating a second problem.

9. Before adding another product, find the cause

Skin breakdown often triggers the same first question:

“What should we put on it?”

Sometimes that is not the best place to start.

First ask:

Why is this happening?

Is the skin exposed to repeated moisture?

Is stooling frequent?

Is there pressure from a device?

Is an adhesive pulling against the skin?

Is there friction?

Is something too tight?

Is the skin being cleaned too aggressively?

Could an antiseptic or topical product be contributing?

Is there a wound that needs a different level of assessment?

A cream cannot fix pressure from an incorrectly fitted device.

A moisture barrier cannot correct adhesive-related skin stripping.

A wound cleanser cannot solve repeated friction.

A stronger product is not always the answer.

Treat the skin, but also identify and reduce the cause whenever possible.

This is where nursing assessment becomes more important than simply knowing the name of every product in the supply room.

10. Describe it, document it, and follow it

Finding the skin problem is only the beginning.

The next step is making sure the team can understand what you saw and determine whether the plan is working.

“Skin breakdown noted” is rarely enough.

Describe:

• The exact location

• Size when appropriate

• Whether the skin is intact or open

• Color and appearance

• Blistering, peeling, bleeding, drainage, or denudement

• Condition of the surrounding skin

• The suspected cause

• Any device involved

• Products or dressings already being used

• Whether the area is improving, unchanged, or worsening

Use hospital-approved clinical photography when appropriate.

Notify the appropriate team.

That may include the provider, wound-care team, vascular-access team, CNS, educator, respiratory therapist, or another specialist depending on the problem.

Then create a follow-up plan.

When will the skin be reassessed?

What change would trigger escalation?

Who is responsible for following it?

Does this event also need to be entered into the hospital's safety-reporting system?

Clear documentation gives the next nurse something to compare against. Without it, each shift is essentially starting over.

Skin care is bedside clinical judgment

The longer I work in the NICU, the more I think some of our most important nursing skills are hidden inside tasks that look routine.

A diaper change is an opportunity to protect the skin barrier.

A bath is an opportunity to decide whether the baby is stable enough for additional handling.

Removing an adhesive requires thinking about the maturity of the skin underneath it.

Preparing for a procedure means balancing infection prevention with the risk of chemical injury.

Noticing redness beneath a device means asking whether the treatment itself is creating a new problem.

Good neonatal skin care does not require memorizing every product.

It requires knowing what you are trying to accomplish, choosing the least traumatic way to accomplish it, understanding the infant in front of you, and recognizing when the current plan is no longer working.

Before you reach for the next product, ask:

What is the purpose?

Why is the skin changing?

Is the current plan helping?

Then protect the barrier, document what you see, reassess, and escalate when needed.

That is not just skin care.

That is NICU nursing.
