Hello,my name is dr Dorina Gurabardhi. Often dry skin is caused by environmental factors, such as cold weather and frequent bathing, and by medical conditions, such as atopic dermatitis and malnutrition. Dry skin develops due to a decrease in the natural oils in the outer layer of skin, which makes the skin lose water. Dry skin is caused by a number of environmental factors including: -Low humidity -Frequent bathing -Harsh soaps Dry skin is caused by several medical conditions including: -Ichthyosis -Atopic dermatitis -Diabetes -Hypothyroidism -Malnutrition Some advices are: -Take a bath or shower only once daily. More frequent bathing can make the skin lose water (dehydrate). -Use lukewarm (not hot) water. -Limit bath time to 15 minutes. -Avoid harsh deodorant soaps (or limit their use to armpits, groin, and feet). -Use non-soap cleansers. -Pat (don t rub) the skin dry after bathing. -Apply moisturizer immediately after bathing, while the skin is still moist. -When choosing a moisturizer, look for oil-based creams and ointments, which work better than water-based lotions. -Creams containing urea -Over-the-counter cortisone cream (if the areas are itchy) -Topical antibiotics applied immediately to any cracks in the skin to help prevent infection.If it gets worse visit a dermatologyst. Hope my answer was helpful,thanks!
