Oily skin: Oily skin can produce enlarged pores, a dull or shiny look, thick-looking complexion, blackheads, pimples, or other blemishes. Oiliness can change depending upon the time of year or the weather. Oily skin can be caused or made worse by hormonal imbalances, stress, exposure to heat or too much humidity.
Combination skin: A combination skin type can be dry or normal in some areas and oily in others, such as the T-zone (nose, forehead, and chin). Combination skin can produce overly dilated pores, blackheads, and shiny skin in the oilier areas; however, it often has no severe sensitivity, barely visible pores in drier areas, and an overall radiant complexion.
Dry skin: Almost invisible pores, dull, rough complexion, red patches, less elasticity, more visible lines. When exposed to drying factors, skin can crack, peel, or become itchy, irritated, or inflamed. If your skin is very dry, it can become rough and scaly.
