There’s a growing children’s skincare market that ranges from the genuinely useful to the completely unnecessary. Baby toners, infant serums, and children’s “age-defying” products exist, and they’re being bought. Meanwhile, what children’s skin actually needs is much simpler than the product shelves suggest.
Most children have naturally healthy skin that requires minimal intervention. When problems do appear, knowing what they are and what helps makes much more sense than reaching for an unnecessarily complex product.
What children’s skin is actually like
Children’s skin is genuinely different from adult skin, particularly in the first few years of life. Infant skin has a thinner stratum corneum (the outermost layer), a higher skin surface pH than adults, and a less mature skin microbiome. These differences mean infant skin is more permeable to topical substances, more reactive to environmental changes, and more prone to dryness and irritation.
By around two to three years of age, most of these differences have resolved and children’s skin functions much like adult skin, just without the hormonal influences, UV accumulation, and lifestyle factors that affect adult skin over time.
Children do not produce sebum at adult levels until puberty, which means they generally don’t have the oiliness issues that drive a lot of adult skincare. Their skin barrier, when intact, is effective. When it’s compromised, it needs support, not a twelve-step routine.
When children don’t need skincare products
A healthy child with no skin conditions, no particular dryness, no atopic tendencies, and no exposure to extreme environmental conditions does not need a dedicated skincare routine. A gentle wash and moisturiser applied if skin looks dry is genuinely enough.
Children don’t need toners, essences, serums, masks, or any active-ingredient products. Active ingredients like retinoids, alpha hydroxy acids, strong vitamin C, and niacinamide at high concentrations are designed for adult skin problems and are not appropriate for children. The safety data on most cosmetic actives simply doesn’t include children as a tested population.
The most important skincare habit to establish in children is daily sunscreen application. UV damage accumulates from birth, and the damage done in childhood and adolescence contributes to skin cancer risk and premature ageing decades later. Teaching children to wear SPF is one of the highest-impact skin health habits there is.
When children genuinely need skincare support
The most common reason children benefit from skincare products is atopic dermatitis (eczema). Around one in five children in developed countries have eczema, making it one of the most prevalent childhood skin conditions. Children with eczema have a compromised skin barrier that allows moisture to escape and irritants to penetrate, causing the characteristic dry, itchy, inflamed skin.
For eczema-prone children, regular moisturising is not optional, it’s therapeutic. Research consistently shows that frequent application of emollient moisturisers reduces the frequency and severity of eczema flares and may reduce sensitisation to allergens. Starting daily emollient use from birth in high-risk infants (those with a family history of eczema) has been studied as a preventive measure, with mixed but somewhat promising results.
The moisturiser for eczema-prone children should be fragrance-free, free of common allergens, and rich in emollient ingredients. For babies and young children, a natural baby cream made without synthetic fragrances, parabens, or potentially sensitising ingredients is the right approach. Coconut oil-based formulations have good evidence for maintaining skin barrier function in eczema-prone infant skin.
Other conditions where skincare support genuinely helps in children include dry skin from cold climate exposure (common in northern Europe), cradle cap (seborrhoeic dermatitis of the scalp), and contact dermatitis from irritant exposure.
What to avoid in children’s skincare
Fragrance is the most important thing to avoid. Fragrance is the leading cause of contact allergic dermatitis in children, and early sensitisation to fragrance compounds can cause lifelong fragrance allergy. Many products marketed for children still contain synthetic fragrance. Read ingredient lists rather than trusting “baby” or “gentle” on the label.
Essential oils are often used as natural fragrance alternatives but can be equally sensitising. Lavender oil, for example, is commonly used in baby products but contains linalool and linalyl acetate, which are known sensitisers. Some essential oils, including eucalyptus, peppermint, and camphor, are not safe for use on or near young children at all.
Methylisothiazolinone (MI) and methylchloroisothiazolinone (MCI), preservatives that have caused widespread contact allergy problems in adults, are particularly problematic in children’s products. They’ve been restricted in leave-on cosmetics in the EU, but check labels on rinse-off products too.
Products with long ingredient lists of unknowns, particularly in rinse-off formats like shampoos and bath washes, have more opportunity to cause reactions. Simpler formulations with recognisable ingredients are better for children.
Building good habits without building complexity
The goal with children’s skincare is to establish a few genuinely healthy habits without creating anxiety about skin or a dependency on multiple products. Daily sunscreen, a gentle cleanser, and an unscented moisturiser when needed covers what most children require.
Teaching children to enjoy caring for their skin as a simple, pleasant part of their day, rather than a complicated ritual or a response to problems, sets a healthy relationship with skincare for life. Less is genuinely more here. The most important thing is what you leave out of their routine, not what you put in.
