This skin is neither too dry nor too oily. It has regular texture, no imperfections and a clean, soft appearance, and does not need special care.
Sensitive skin is more prone to react to stimuli to which normal skin has no reaction. It is a fragile skin, usually accompanied by feelings of discomfort, such as heat, tightness, redness or itching.
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 In many cases, dry skin is caused by external factors such as the weather, low air humidity and immersion in hot water, and it is usually temporary. However, for some people it may occur more often and even be a lifelong condition. Since dry skin can crack leaving it more exposed to bacteria, although in general this is not serious, it may cause other skin disorders, such as eczema, or be more prone to infections if not properly managed.
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.
Oily skin has a porous, humid and bright appearance. It is caused by excessive fat production by sebaceous glands, and usually determined by genetic and/or hormonal causes. It is frequent in adolescents and young people under 30 years old, and usually related with the occurrence of acne.
Based on its location, it presents characteristics of both dry and oily skin since the distribution of sebaceous and sweat glands is not homogeneous. The area with more oil is usually the T- zone (forehead, nose, and chin), while the skin on the cheeks is normal or dry.
