Baby Skincare: What Newborn Skin Actually Needs (Less Than You Think)

The baby skincare market is vast, fragrant, and largely unnecessary. Walk into a pharmacy and you will find entire ranges of products — cleansers, toners, lotions, oils, barrier creams — all presented as essentials for your newborn. In reality, healthy newborn skin needs very little. Understanding what is genuinely useful and what to avoid will save you money and, more importantly, protect your baby's developing skin barrier.

What Newborn Skin Is Like

A newborn's skin is covered in vernix — a white, waxy coating that serves as a natural moisturiser and barrier. The NHS recommends leaving vernix on the skin and allowing it to absorb naturally. Bathing it all off immediately after birth removes this natural protection.

Newborn skin is around 30 per cent thinner than adult skin. The skin barrier — the outermost layer that prevents water loss and keeps irritants out — is immature and developing during the first few months of life. This makes newborn skin more permeable: substances applied to it are absorbed more readily, and water is lost from it more easily.

This is precisely why less is more. Every product you apply has the potential to disrupt the developing skin barrier. For babies with a family history of eczema, atopic conditions, or sensitive skin, the argument for a minimalist approach is even stronger.

Bathing: How Often and What to Use

In the first few weeks, top-and-tail washing — a warm, damp cloth to wipe the face, neck folds, hands, and nappy area — is sufficient. Full baths two to three times a week is plenty for most babies. Daily baths are not necessary and can dry out the skin.

Water alone is the safest option for bathing newborns. The NHS recommends using plain water for at least the first month. If you want to use a product, choose one specifically formulated for newborns, fragrance-free, and ideally with a neutral or slightly acidic pH that matches baby skin.

What to avoid in bath products:

• Fragrance (labelled as "parfum" in ingredient lists): even natural fragrances are common skin sensitisers and can contribute to eczema development
• Sodium lauryl sulphate (SLS) and sodium laureth sulphate (SLES): harsh surfactants that strip the natural skin barrier
• Antibacterial ingredients (triclosan, chlorhexidine in routine washes): unnecessary for healthy skin and potentially disruptive to the skin microbiome
• Parabens: preservatives that some parents prefer to avoid, though current evidence does not confirm harm at the concentrations used in cosmetics
• Alcohol (ethanol): drying and irritating

What is acceptable in baby bath products:

• Mild surfactants such as cocamidopropyl betaine or decyl glucoside
• Glycerin as a humectant
• Simple emollient ingredients

Moisturiser: When and What

Healthy newborn skin does not routinely need moisturiser. If your baby's skin looks and feels normal, there is no evidence that applying a daily moisturiser prevents eczema or improves skin health — some research has actually suggested that routine emollient use in all babies may increase eczema risk in some populations, possibly by altering the skin microbiome.

If your baby has dry, flaky, or rough patches — or if they have a family history of eczema — a fragrance-free, simple emollient can be helpful. Options recommended by dermatologists and the NHS for sensitive or eczema-prone skin include:

• Diprobase cream or ointment
• Cetraben cream
• Hydromol ointment
• Doublebase gel

These are unfussy, inexpensive, and available from pharmacies. Avoid products labelled "baby lotion" that contain fragrances or complex ingredient lists.

Baby Oil: Is It Safe?

Pure mineral oil (such as Johnson's Baby Oil, original formulation) has a long safety record and is non-sensitising for most babies. Olive oil, which was previously recommended, has been shown in research to disrupt the skin barrier and is no longer recommended by UK dermatologists for routine baby skincare. Sunflower oil appears safer in this regard, but for a baby who is not dry or eczema-prone, oils in general are not necessary.

Nappy Area Care

The nappy area deserves its own approach because it is constantly exposed to moisture, urine, and faeces — all of which can break down the skin barrier and cause nappy rash.

Change nappies frequently. Clean the area thoroughly at each change with plain warm water or unscented baby wipes (water-based wipes are gentler than those containing alcohol or fragrance). Pat dry rather than rubbing.

A barrier cream — applied thinly at each change — helps protect the skin. White soft paraffin (petroleum jelly) is the simplest and most effective option. Zinc oxide-based creams such as Sudocrem are also widely used and effective.

Nappy rash that does not clear with barrier cream within a few days, or which appears bright red and raw with satellite spots, may be a fungal infection and warrants assessment by a GP or health visitor.

Sun Protection

Babies under six months old should not be in direct sunlight. Keep them in the shade, use a pram hood or sunshade, and use lightweight, covering clothing. Sunscreen is not recommended for babies under six months.

For babies over six months, use a sunscreen with SPF 30 or higher and broad-spectrum UVA/UVB protection. Choose a mineral-based formula (zinc oxide or titanium dioxide) rather than chemical UV filters if your baby has sensitive skin.

The Minimalist Approach

Healthy newborn skin: plain water for bathing, no products needed. For dry patches: a simple, fragrance-free emollient. Nappy area: barrier cream at every change. That is genuinely all that most babies need. Save the elaborate skincare routines for later — or skip them altogether.
