In general terms, dry skinitchy, tingling and itching, especially in the arms and legs, can be caused by several factors.
Causes of dry skin
First of all, the loss of water from the stratum corneum, the most superficial one of the skin. A dehydration of 10% is enough, because the skin becomes less elastic.
The second factor is the acceleration of cell turnover linked to irritation from ultraviolet rays. Or even from substances that can induce allergies, when obviously these stimuli are maintained over time.
The third factor, more important from a dermatological point of view, is related to lipid reduction that make up the skin. When this phenomenon occurs, the epidermis can no longer hold water and becomes drier. In these cases, the skin tends to become dull, grayish, rough to the touch and to undergo a more or less intense flaking. Above all, it becomes less elastic and less soft.
Dry skin, how to prevent it
At the level of therapies, the dermatologist must indicate the right therapy. But on the prevention front, it must be remembered that wind, cold and excess sun are enemies of the skin. But there are apparently healthy habits that can cause problems for some people. For example, frequent baths and showers with hot water, aggressive soaps, degreasing shampoos are not particularly suitable. Some attention should be paid to clothing, as synthetic clothing can exacerbate problems for those who are sensitive.
In some cases, dry skin can result from drug treatments. There are drugs based on retinoids, which are used for the treatment of acne, those that fight intestinal spasms, diuretics to control blood pressure can have the onset of this disorder as a side effect.
Dry skin, a symptom of disease
Dry skin can also be symptom of diseases affecting other bodies. For example, in case of renal insufficiency, thyroid disorders or when there are skin diseases, such as psoriasis and atopic dermatitis.
