How can you tell your skin type? Sensitive skin reddens easily and stings or burns when you apply most products. For the other types, the condition of your T Zone (across your forehead and a straight line down your chin) will help you identify which category you fit in. At the end of the day, examine the area. A matte surface means dry skin, a greasy or shiny zone translates to oily, and if your face is just slightly slick, you have normal or combination skin.
