Alcohol dries the skin.
Cut down your use of soap in general. Sometimes when suffering from dry itchy skin, the static electricity between the sheets in bed can be uncomfortable. You can reduce the static electricity by changing only one sheet at a time. Mention your dry skin concerns to your health professional. You can't turn back the hands of time.
