Newborn skin is thinner, more permeable, and less effective as a barrier than adult skin. What you put on your baby's skin matters more than most parents realise — especially in the first few months.
Why Baby Skin Is Different
Newborn skin has a higher pH than adult skin (less acidic) and a thinner stratum corneum (the outer protective layer). The skin microbiome is not yet established. This makes newborn skin more vulnerable to irritants, allergens, and infections than adult skin.
Ingredients to Avoid
| Ingredient | Risk | Where Found |
|---|---|---|
| Fragrance / parfum | Contact dermatitis, allergic sensitisation | Most 'baby' lotions |
| Essential oils | Highly concentrated plant extracts — irritants and allergens | 'Natural' baby products |
| Propylene glycol | Potential irritant and penetration enhancer | Creams, lotions |
| Sodium lauryl sulphate | Stripping detergent — disrupts skin barrier | Baby wash, shampoo |
| Parabens | Endocrine disruption concerns (at high concentrations) | Preservatives |
| Methylisothiazolinone (MI/MCI) | Common sensitiser — causes allergic contact dermatitis | Rinse-off products |
The Less-Is-More Approach
Many dermatologists recommend using as few products as possible on newborn skin for the first 4–6 weeks. Plain water for bathing, a plain emollient for dry skin if needed, and nothing else. This approach prevents unnecessary sensitisation.
What Is Generally Safe
- Fragrance-free, dye-free baby wash and shampoo
- White soft paraffin (Vaseline) or plain zinc cream for the nappy area
- Simple, fragrance-free emollients like Cetaphil, QV, or Aveeno fragrance-free for dry skin
- No baby oil in the first weeks — oils on dry skin can actually worsen barrier function
Singapore climate
Singapore's high humidity means baby skin is rarely as dry as in temperate climates. Less moisturiser is often needed. Prickly heat (miliaria) is more common — avoid heavy creams that block sweat glands.
