What is the atopic dermatitis?

Atopic dermatitis is a skin disorder that causes redness and itching. ANDIt's more common in children, but it can occur at any age. It is usually lasting or chronic, but it remits for some periods and then it is exacerbated.

It is believed that this disease currently affects approximately 20% of children worldwide. It is a little more frequent in the developed countries of the northern hemisphere, but it takes place all over the planet. Between 3 and 5% of children who have atopic dermatitis will continue to suffer until adulthood.
