Oily skin tends to produce an excess of sebum, leading to a shiny appearance and sometimes contributing to acne and other skin issues. For individuals with oily skin, using oil-free products is essential. These products help to maintain the skin's balance without adding extra oil, which can aggravate oiliness and exacerbate acne. Oil-free formulations, including cleansers, moisturizers, and makeup, are specifically designed to provide hydration and nourishment without overwhelming the skin with additional oils that can lead to clogged pores.

The other statements do not accurately represent the typical characteristics of oily skin. While oily skin can occur frequently, it is not universally the most common skin type, as skin types can vary widely among individuals. Oily skin can also be sensitive, but this is not a definitive characteristic; not all individuals with oily skin experience sensitivity. Lastly, oily skin appears shiny and may have enlarged pores, making it the opposite of dry skin, which would typically have a lack of oil and a dull appearance.
