A combined skin is characterized in that the t-zone (forehead, nose and garden) is a bit more greasy than the skin in the rest of the face. The T-zone often also tends to get impurities and clogged pores because our sebum production is more active in this area. Much of the skin's condition lies in the genes, but many find that their skin can sometimes be combined. This can be caused by seasonal shifts or lifestyles. If the skin is very combined, that is, very fat in the t-zone, and extra dry around the cheeks, it may be necessary to use skin care for two skin types. But usually you can find products that can be used throughout the face and help to normalize the skin condition. Over time, our sebum production will slow down, and this can make the skin condition completely stabilized. But otherwise, just make sure to find some products that match the skin type and give a good feeling. It may be that you should pay extra attention to exfoliating the skin in the greasy area, and perhaps just use skintonic in this area, or at least use one that is good for oily skin. A lot of people have a combined skin, which is why it is the most common skin type.
