Xerosis is an abnormal dryness of the skin or mucous membranes. It is also called a dry skin condition. Xerosis is usually a long-term problem that recurs often, especially in the winter. This is most common during the winter months, when heating systems dry the air. Bathing with hot water, spending extended periods of time in the hot sun, and the skin's natural aging process also remove moisture and oils from the skin. During the winter, dry skin, or xerosis, occurs in more than 75% of persons who live north of the 37th parallel in the United States. There are different types of xerosis:
- Corynebacterium xerosis
- Corneal xerosis
- C xerosis
Cold winter weather can be hard on skin because the amount of moisture is less than the amount of moisture in warm air. When this oil layer is gone, evaporation of water from the skin occurs and the skin dries and cracks like mud in the desert. When the humidity is high less evaporation occurs, but during times of low humidity evaporation proceeds rapidly and xerosis becomes more prominent. Diseases that can cause dry skin and mild generalized pruritus include end-stage renal disease, obstructive hepatobiliary disorders, diabetes, thyroid disease, hyperparathyroidism, and Hodgkin's disease.
The symptoms of dry skin include itching, flaking, and fine lines. Xerosis of the foot is common in patients withdiabetes and can lead to severe complications, such as ulcers, infections, and cracks in the skin.
Dry skin is not a very big problem we can treat it home if possible eat a balanced diet. Do exercise daily and drinking plenty of water contribute to healthy, supple skin? If you like to outside in the sunny place then wear a sunscreen with a sun protection factor of 15 or higher.
Severe xerosis, as in diabetic patients, is treated with a prescription medicated lotion. In some cases, xerosis can cause severe complications in diabetic patients, requiring amputation of the foot. Skin needs to be hydrated from the inside, too, to feel comfortable and stay in good condition. Remember to drink plenty of water; keep a water bottle in your backpack, to remind you to drink plenty throughout the day.
Reduce how often you bath or shower, using lukewarm water. Showers are better than baths. Replace standard soap with a substitute such as a synthetic detergent, water-miscible emollient, bath oil, anti-pruritic tar oil, etc. Apply an emollient liberally and often, particularly after bathing, and when itchy.
