Which of the following is NOT a characteristic of oily skin?

Flaky texture is not a characteristic typically associated with oily skin. Oily skin tends to produce excess sebum, which keeps the skin moist and can result in a shiny or greasy appearance. This excess oil can lead to clogged pores, contributing to issues like pustules and spots. On the other hand, flaky texture is generally indicative of dry or dehydrated skin rather than oily skin. Therefore, individuals with oily skin usually do not experience the dryness and flakiness that defines other skin types, making flaky texture an anomaly in this context.
