Normal skin is balanced feeling neither dry nor oily. It is not prone to breakouts, flakiness, feeling slick or tight. Pores are generally small, the skin's texture is smooth, and it is less likely to be prone to sensitivity or blemishes.
Dry skin is typically dull and may become rough, flaky or even scaly. It often feels tight or less
Oily skin produces an excess of sebum that causes the skin to appear shiny and feel greasy-especially throughout the T-Zone (forehead, nose and chin). If you have oily skin, you may be more likely to have enlarged pores, develop acne blemishes and be more prone to acne breakouts.
Combination skin includes areas that are dry as well as oily with the T-Zone commonly being oily, and the cheeks being either dry or normal.
