The easiest way is to wash your skin with a gentle, non-foaming cleanser and then wait 30 minutes. If there’s shine and visible pores in the T-zone with normal or dry cheeks, you have combination skin. This is the most common skin-type, affecting around 2/3 of us. If there is oil all over, your skin type is (unsurprisingly) oily. If your skin is comfortable, your skin type is normal. If it’s tight or flaky, it’s dry.
