Oily skin is a common skin type characterized by an overproduction of sebum, which is a natural oil produced by the sebaceous glands. This excess oil can lead to a shiny appearance, enlarged pores, and increased acne or blemishes. To manage oily skin, it's essential to maintain a consistent skincare routine that includes cleansing, exfoliating, and moisturizing with oil-free products. Additionally, consider using oil-absorbing sheets, blotting papers, and avoiding heavy makeup or products that may further exacerbate the oiliness.
