This type of skin loses its barrier (or protective) function, making it easy for microorganisms and irritant substances to enter it, and increasing the possibility of having an infection and allergic reactions. It is a delicate skin that needs more care to fight dryness, roughness and its usual appearance.
Sometimes, it is referred to as irritated skin instead of sensitive, but these terms are synonymous and there are no dermatological differences between them.
Dry skin signs and symptoms may vary depending on different factors such as age, health status or their cause. It is generally characterized by a feeling of tightness and roughness. It may also acquire an ashy gray color, with occurrence of desquamation, itching, redness and small cracks. Cracked skin is usually observed in very dry skin and presents small cracks, which, in more serious cases, may be deeper and even bleed.
Atopic skin is a skin disease characterized by dry skin that leads to desquamation and irritation and causes upsetting symptoms, such as itching. The main cause is genetic predisposition, although other factors may trigger its occurrence or aggravate the condition as well, which may be environmental, allergic, related with food and even with some clothes.
