This is easy, but it’s important - using the incorrect product on your skin may aggravate problems. Poor cleansing of combination skin may make it seem oilier than it really is. Using astringent preparations on normal skin may make it dry.
Here’s what to do: wash your face, then wait for an hour, without applying any skin care product to it. Then press a tissue to each of the following areas of your face: your nose, cheeks, chin and forehead.
