Skin types are generally divided into five main categories: normal, dry, oily, combination and sensitive skin. Normal skin, which has a balanced oil and moisture ratio, does not require much care. Dry skin, which can be tight and flaky due to lack of moisture, can make fine lines and wrinkles more visible. Oily skin, which has a shiny and oily appearance due to excess sebum production, can be prone to large pores and acne. In combination skin, the T-zone of the face, namely the forehead, nose and chin, is usually oily, while other areas are dry or normal. Sensitive skin, which can be easily irritated, can show reactions such as redness and itching. Determining your skin type is extremely important in terms of choosing the right products and applying the right skin care.
