Do your skin's hydration needs change with the seasons? What might work best in the hot, humid summer months may not tame oil production effectively during the colder, dryer wintertime. Depending on the temperature and humidity, you might need to scale back or bump up your moisturizing needs. Also, don't shy away from trying different products during different seasons. Stick with lightweight lotions, and use only as much as you need, which may be less on certain days or certain times of the year.
And it's not just the seasons that have an effect on how oily or dry your skin may be. Watch out for flare-ups from hormonal changes, certain medications (such as steroids) and even the frames of your glasses or the chin strap of your bike helmet (the pressure from the glasses on the bridge of your nose or strap on your chin can be irritating for some oily-faces).
