For combination skin
Most of us have combination skin. Combination skin tends to have oilier areas on the forehead, nose and chin ("T-zone") and dry areas on cheeks and around the mouth and eyes. In the T-zone area, the pores are slightly enlarged. Here there can be an oversupply of sebum, which can lead to impurities. Combination skin is very sensitive to changes in weather and temperature.
