Baby's skin

In babies, their skin is characterized by being thinner and more predisposed to suffer irritation.

The skin of the baby is very different from that of the adult. It is thinner, with less hair, produces less sweat and also a smaller amount of sebaceous secretions. These differences are even more evident in premature babies.

Atopic dermatitis of the infant

One in ten babies can suffer from this disease during the first three months of life. This type of dermatitis usually appears on the cheeks, neck and arms.

It is relatively common in newborns and they suffer between 2 and 5% of the babies disappearing at 8 months although later, during adolescence, it may reappear in the form of dandruff. Many new parents are scared but usually it is nothing to scare and with proper products disappears.

It can occur for different reasons such as carrying the diaper dirty of urine and feces for a long time, the friction of the diapers very tight with the natural movement of the child or even because the skin of the baby is sensitive to certain products or substances that make up the diaper as well as certain laundry detergents, soaps, wet wipes …

On the other hand, the plastic that covers the diaper prevents the correct circulation of air in the area, which facilitates the proliferation of fungi and eruptions. If we see that the irritation lasts more than three days, it may be due to the appearance of the candida albicans fungus that causes red eruptions bulging so we should visit the pediatrician.
