Young skin looks and functions differently to adult skin. The self-protection mechanisms prevalent in healthy adult skin are less developed and, as a result, babies and children need special care to keep their skin feeling and looking healthy.

Understanding baby skin

Baby skin is thinner and more delicate than adult skin. It reacts more sensitively to external aggressors and needs extra special care and protection against environmental stressors that cause dryness.

A baby’s skin needs special care, as it is only one-fifth the thickness of adult skin.
Baby skin is less resistant, prone to drying out and more sensitive to UV rays.

Baby skin has the same number of layers as adult skin but each layer is considerably thinner. Overall baby skin is just one-fifth of the thickness of adult skin.

As a result, the moisture barrier function is limited: 

  • Baby skin is less resistant than adult skin and especially sensitive to chemical, physical and microbial influences: Substances that come in to contact with baby skin are absorbed more easily and penetrate into deeper skin layers.
  • Baby skin is prone to drying out.
  • Baby skin is more sensitive to UV rays than adult skin.

Sensitivity to UV is further enhanced by low pigmentation in baby skin. Melanocytes (the cells responsible for melanin production) are present, but less active.

How does skin change during childhood?

Until the age of 6, a child’s skin is thinner and weaker than adult skin.
Male and female skin has similar characteristics until puberty.

As children mature, so does their skin. From birth to the approximate age of 6:

  • Skin is still thinner and has less pigmentation than adult skin.
  • Sweat and sebaceous glands are still less active so the hydrolipid film and protective acid mantle are still relatively weak.

By the approximate age of 6, the structure of skin and its appendages is fully matured and corresponds to that of an adult.

Sebaceous gland activity does not increase until the hormonal changes of puberty, which occur at the approximate age of 12. These hormonal changes also bring about differences between the structure and behaviour of boys and girls skin, which, up until then, has been the same.

Childhood skin conditions

Atopic Dermatitis

Atopic Dermatitis (also known as Atopic Eczema) is one of the most common skin diseases of childhood and affects between 10 and 20% of children globally. In a third of these cases the disease fades out during childhood but, for others, it can continue into adulthood.

A non-contagious but distressing and sometimes painful condition, Atopic Dermatitis typically goes through 2 phases. An inactive phase, where skin is very dry, irritable and flaky and needs to be moisturized on a daily basis and an active phase (or ‘flare-up’) where skin needs to be treated with topical medications to calm inflammation and alleviate itching.

What are the causes and triggers?
Atopic Dermatitis is thought to be genetic. There is a known link between Atopic Dermatitis, hay fever and asthma and evidence shows that if either or both parents suffer from these conditions, their children will be more prone to Atopic Dermatitis. Research has also shown that children from developed countries living in urban areas where the intensity of pollutants is higher, as well as those living in cold climates, are more likely to develop the condition.

Once affected, there are a number of reasons why symptoms get worse or flare-ups occur. Sufferers are known to have a deficiency of important lipids and Natural Moisturising Factors (“NMFs” such as Urea and amino acids). As a result their skin’s moisture barrier function is weakened, moisture loss is increased and they are prone to dryness. A compromised moisture barrier function means that harmful substances like allergens and irritants can penetrate and skin becomes infected more easily. Sufferers are also known to have an irregular immune function (known as atopy), which makes their skin more reactive to the environment and susceptible to inflammation.

Problems are often caused when the child scratches an itch and disturbs their already fragile skin barrier. This causes bacteria called Staphylococcus Aureus to multiply and infect the skin. The infection causes inflammation, which causes itching which further worsens the condition: a vicious process known as the Atopic Skin Cycle. Read more in Atopic Dermatitis.

Babies can develop eczema on their face, scalp, knees and elbows.
Symptoms usually start with a rash that has itchy, scaly patches.

What are the symptoms in babies?
Atopic Dermatitis is rare in infants under 3 months. Symptoms typically develop after a baby has been weaned: a rash appears suddenly making skin inflamed and itchy. In flare-up phases, infected skin may ooze fluid. Babies typically get Atopic Dermatitis on their face – particularly the cheeks - and scalp (also known as ‘cradle cap’), the knees and elbows. It is very rare for babies to develop atopic skin in the nappy area. Although nappy rash may look similar, it is too moist an area for Atopic Dermatitis to develop. 

What are the symptoms in children?
Children who develop the disease later in life (between the ages of 2 and puberty) usually start with a rash on the body, which is dry with itchy, scaly patches. Skin tends to be bumpy, thickened and leathery. Common areas affected are the creases of the elbows or knees, neck, wrists, ankles and/or the creases between the buttocks and legs. 

Due to the fact that symptoms often persist for more than 3 months (the medical definition of a chronic disease), the skin in the inflamed areas can thicken. This is known as lichenification.

Caring for baby and children’s skin

Young skin needs particular care:

  • Use mild cleansers: Alkaline soaps are aggressive on skin, remove lipids and dry it out.
  • Limit bath time: Hot water and long baths remove lipids from skin. Reduce time and use warm, rather than hot, water.
  • Care: Regular moisturisation with products tested on, and proven to be compatible with, sensitive skin will help to keep young skin hydrated and healthy looking. Care products should also be used to target and treat specific concerns and conditions. 
  • Protect: Young skin needs particular protection from harmful UV rays.
