Skin type can be determined by looking in the mirror:
Normal skin – pores are virtually invisible. Skin looks smooth and even.
Oily skin – enlarged, visible pores. Sebum secretion with very few wrinkles. Some oily parts of the skin look shiny.
Combination skin – oily skin in some areas of your face and dry skin in other areas. Usually, the T-zone (the center of the face) is oily and other parts of the face are dry or normal.
Dry skin – shows a tendency for wrinkles. Pores are virtually invisible. Skin lacks moisture and feels tight and uncomfortable.
