Combination skin
It is typical for combination skin that some areas show symptoms of dry skin and other areas show symptoms of oily skin. The forehead, nose and chin (known as the T-zone) are usually shiny and oily, and may even be blemished, while the cheeks are dry, dull and flaky. The T-zone usually tends to suffer from seborrhoea, i.e. an overproduction of sebum. On the cheeks and sometimes in the area around the eyes, too little sebum is produced.
Factors that can lead to combination skin include hormones, stress, diet or incorrect care. In this case, you are causing the dry or oily areas yourself. Care products that are too harsh or aggressive can dry out areas of the face while simultaneously stimulating oil production in other areas.
Combination skin needs moisture and it may also make sense to use different products on the individual zones.
