Final answer:
Combination skin typically features an oily T-zone and dry cheeks, with acne common in oily areas due to hormonal changes. Eczema can also occur in dry areas of combination skin.
Step-by-step explanation:
The most common characteristics of a combination skin type are having areas that are both oily and dry. Typically, the T-zone (forehead, nose, and chin) tends to be oily, while the cheeks and eye areas may remain dry. This skin type may experience acne primarily in the oily areas due to the overproduction of sebum, a natural skin oil, which is known to be more prevalent among teenagers and young adults due to hormonal changes.
Conditions such as eczema, which presents as a red, flaky rash, can also occur in the drier regions of combination skin. Regardless of skin type, it's important to follow a skincare routine that manages both oiliness and dryness effectively, taking into consideration that some skin conditions might resolve without treatment.
