Cleanse your face thoroughly with a mild cleanser and gently pat dry. Leave skin bare (and do not apply any additional moisturizers, serums or treatments). After 30 minutes, examine your cheeks, chin, nose and forehead for any shine. After another 30 minutes, evaluate whether your skin feels parched, especially if you smile or make any other facial expressions. If your skin feels tight, your skin is likely dry. If there is noticeable shine on your nose and forehead, your skin is mostly likely normal/combination. If there is shine on your cheeks in addition to your forehead and nose, you most likely have oily skin.
