Normal Skin: Some consider normal skin to be combination skin, but it is not. If your skin is oily in the "T zone" and your nose while dry and taut on the cheeks, it is considered normal. It's also considered normal if it changes with seasons (dryer in winter, oilier in summer). Normal skins can also be 'Normal-To's' as in normal to oily or normal to dry.
Treatment: Wash your face with cleansers that are designed for your normal/normal-to skin type. Wipe an alcohol free, hydrating toner all over the face. Apply moisturizer more frequently to dry skin.
