As the seasons change, so does your skin. A good rule of thumb is to match your face moisturizer to your wardrobe. In warmer months, a lightweight moisturizer will generally do the trick. The dry, blustery days of fall and winter can be more trying on the skin, so you may want to switch to a skin moisturizer that's more hydrating. Rich balm or cream formulas are excellent choices for day creams in winter, while gel creams or fluids may be better for your skin in summer.
