Like the “Bare Face Method” after you cleanse and pat down your face, wait around 20 - 30 minutes without applying any skincare. Now apply a blotting sheet or a tissue on the following areas; your forehead, nose, cheeks, and chin. Carefully observe the amount of oils that the blotting sheet picked up, or if the blotting sheets stuck to your skin in certain areas.
If barely any oils were transferred onto the sheet, you most likely have dry skin. If the blotting sheets were able to stick all over your face, and a decent amount of oils was transferred onto the sheet, you most likely have oily skin.
On the other hand, if the blotting paper picks up more oils in some areas (usually the T-zone; forehead, nose and chin) and nearly none in other areas (usually the cheeks) of your skin you have combination skin.
Finally, if your skin did not produce too many oils but wasn't left feeling dry and flaky you have normal skin.
