Final answer:
Differences in the T-zone compared to other facial areas, such as an oily T-zone and drier cheeks, signify combination skin, requiring targeted skincare strategies.
Step-by-step explanation:
The differences in the T-zone (the region of the forehead and nose) from other areas of the face, such as drier cheeks, are characteristic of combination skin. People with combination skin often experience an oily T-zone, where there is a higher concentration of oil-producing glands, while other parts of the face may be normal or dry. This requires specific skincare strategies to balance the differing needs of these areas, often involving the use of various products to target the distinct characteristics of the T-zone and the other facial regions.
