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