Cold winds: If the skin is exposed to the chilly winds outside for a long time, it loses moisture.
Skin Barrier Damage: If the skin barrier is damaged, it stops locking in the moisture and the skin becomes dull and dry.
Indoor heaters and fireplaces: Prolonged exposure to heat makes the skin retain less water.
