Use a humidifier to increase air moisture. This helps to stop skin dryness or becoming chapped.
In winter, remember to moisturize the skin frequently. Oily skin moisturizers will be more effective, as they can better prevent moisture loss.
As for hot and sweaty skin areas, avoid using ointment skin moisturizers, as they contain lots of oils.
Before going outside, use oily skin moisturizers plus sunscreen, this can protect face, neck and hands.
Put on gloves, since the winter air is cold and humidity is low. Cotton mitten and woolen mitten can help to keep the hands warm and comfortable.
