When selecting makeup for oily skin, which factor is most important?

When selecting makeup for oily skin, the use of matte-finish products is the most important factor. Oily skin typically produces excess sebum, which can lead to shine and make makeup appear less polished over time. Matte-finish products help to absorb this excess oil and provide a more velvety appearance, minimizing shine throughout the day. They are formulated to reduce the reflective properties that can be accentuated by oily skin, ensuring that the makeup lasts longer and maintains a refined look.

In contrast, heavy oil-based formulas can exacerbate oiliness and lead to a greasy finish, while hydrating ingredients may make the skin feel more comfortable but could potentially contribute to additional shine. The choice of bright and vibrant colors is more about aesthetic preference than addressing the specific needs of oily skin, making it less critical in the selection process.
