Dry skin is thought due to a deficiency in the oily film on the skin surface, rather it is also due to primary loss of water from the outer layers of the skin. The moisture in the air is actually good for skin. If you live in a low-humidity climate or you are around furnaces in the winter, invest in a humidifier. Your skin needs more than 30 percent humidity to stay properly moisturized. A room heated by a furnace can have as little as 10 percent moisture. In the winter, consider sleeping with a humidifier in your bedroom. Keep doors closed so the moist air doesn’t escape the room.
