As soon as the cold weather hits and the heat gets turned on, skin gets drier more quickly! You may have a moisturizer that works well for spring and summer, but as the cold temperatures bring on the indoor heat (whether it's wood, oil or gas) the moisture content in the air drops. During the winter use an oil-based (rather than water based) oil. It will create a protective layer on the skin that retains more moisture than a cream or lotion. Choose your oils with care because not all oils are appropriate for the face. Look for non-clogging oils like avocado oil, mineral oil, primrose oil or almond oil. Find a moisturizer that contains a humectant (like glycerine, sorbitol and/or alpha-hydroxyl acids) because they attract moisture to your skin.
