What type of skin condition is characterized by an increase in pore size?

The correct answer is oily skin, as this condition is frequently associated with enlarged pores. Oily skin tends to produce excess sebum due to overactive sebaceous glands. This increased production of oil can lead to clogged pores, which subsequently stretch and appear larger. The visibility of pores is often more pronounced in individuals with oily skin because the accumulation of oil, dead skin cells, and debris contributes to their size.

Sensitive skin, while it can exhibit various reactions and discomfort, does not specifically correlate with pore size. Combination skin features both oily and dry areas, but the characteristics of pore size primarily reflect the oily regions rather than an overall increase across the skin. Normal skin is characterized by a balanced production of oil and moisture, which typically results in a smaller appearance of pores. Therefore, oily skin stands out as the correct choice due to its direct relationship with increased pore size.
