Dry skin can occur in a short amount of time (sudden onset) or it can happen over long periods of time, becoming dryer and dryer over months or years. The dry skin can be scaly, cracked, itchy, irritated or painful and can even occur around the mouth, lips, nails, elbows and heels of the feet. Due to the long-term dryness of the skin, it can be left susceptible to infection, rash, itchiness or eczema, on top of the simple dryness. These symptoms can come and go, be mild or serious, and all depends on the individual’s certain condition.
