1) Moisturize more frequently. Colder weather removes essential moisture from your skin. Apply moisturizers more frequently and look for products that contain hyaluronic acid which helps to attract and lock-in moisture.
2) Exfoliate. Unwanted, dead skin cells sit on the surface and can block the absorption of moisturizing ingredients, so exfoliate more frequently with an exfoliator that is GENTLE and non-irritating. Avoid harsher exfoliants that contain walnut shells or astringent acids.
