The best moisturizer for oily skin is one that is lightweight, non-comedogenic (which means it won't clog your pores) and oil-free. Those thick, heavy creams aren't designed with oily skin in mind. A light, oil-free formula won't fight blemishes, but it won't cause breakouts, either. Additionally, some moisturizers also contain ingredients such as talc to control shine, and if you want your lotion to help control acne flare-ups, look for one with anti-bacterial agents. There's a moisturizer out there for every skin type -- it just might take some trial and error to figure out which one works the best for you.
