Oily skin is a common skin type that is characterized by excess sebum production. Sebum is a natural oil that helps to keep the skin moisturized, but too much sebum can lead to a greasy, shiny appearance, and clogged pores.
There are a number of factors that can contribute to oily skin, including genetics, hormones, and diet. Oily skin is often associated with acne, as the excess sebum can provide a breeding ground for bacteria. However, there are a number of things that can be done to combat oily skin and improve its appearance.
