Use a humidifier to moisturize the air in your home and apply shea butter or Vaseline on your
lips. You can also use a homemade ointment mixed from 1 tsp
glycerine, 1 tsp lemon juice and 1 tsp castor oil. Spread on lips overnight, refrigerating the leftovers for future use.
Eat foods high in calcium, magnesium and flaxseed oil. If a week of compresses and emollients don't do the trick, you can add over-the-counter 1 percent hydrocortisone ointment to your regimen.
