Xeroderma Underlying Cause

The skin contains sebaceous glands, which produce oils for the skin surface. The oil helps the skin retain water in the cells, making the skin waterproof. Oil production decreases with age. Conditions that reduce the amount of oil or cause evaporation of water from the skin can cause dryness.

Additional causes of dry skin include:

  • Bathing in hot water
  • Bathing with strong soap
  • Forced air heating
  • Sun bathing
  • Hair dryer
  • Winter season
