Winter Skin Care News Cold winter air is far less humid than warm air, which means skin will be drier in the winter months. Harsh winds make conditions worse by causing moisture to evaporate more quickly from the skin. According to dermatologists, indoor conditions in the winter can be just as bad for complexion. Indoor heating is abusive for the skin. It pulls the moisture out of the air, which is dehydrating. The older one gets, the drier the skin gets. The glands in skin get smaller and begin vanishing. This diminishes their ability to hydrate. The consequence is drier skin. <br> <br>
