Use a moisturizer every morning and night. There are many cream like or lotion like moisturizers in drugstores. But if your skin is really dry, using a facial oil is better, such as jojoba oil or camellia oil. I've used both oils and prefer camellia, because it's more moisturizing than jojoba. Best of all, the Silkia camellia oil I used helped tremendously with plumping up my pitted acne scars.
