An oily skin type can have enlarged pores, shiny texture, and blemishes such as blackheads and pimples. Our skin produces natural oil in the sebaceous glands, known as sebum. This natural oil is crucial for keeping the skin healthy as it helps to lubricate the skin, preventing it from drying out or becoming irritated. It is very common for us to have a certain amount of natural oil as it keeps our skin supple and moisturised. The prime factors responsible for oily skin are genetics, gender, age, diet, and weather conditions.
