Too much soapy water, exposure to harsh chemicals, the normal aging process and certain types of skin
diseases are some of the causes of decreased amounts of protective skin
oils which in turn causes dry skin.
The mainstay of management is liberal use of moisturizers after washing with luke warm water. Soap should be used minimally. Moisturizers should be reapplied liberally during the day. You can also use a topical cortisone (steroid) cream or ointment like dermacort(hydrocortisone).
