Oily skin is characterized by an overproduction of sebum, a natural oil produced by the sebaceous glands. This excess oil can lead to a shiny complexion, enlarged pores, and a higher likelihood of developing acne and blackheads. Factors contributing to oily skin include genetics, hormonal fluctuations, diet, and inappropriate skincare products. Managing oily skin involves using gentle, foaming cleansers, oil-free moisturizers, and products containing ingredients like salicylic acid, benzoyl peroxide, or retinoids to control oil production and prevent breakouts. Regular exfoliation can also help to keep the skin clear and balanced.
