There are a few reasons why your face might be oily. One of the most common reasons is genetics. If your parents have oily skin, you are more likely to have oily skin as well. Another reason could be your hormones. Your hormones can affect the amount of oil your skin produces. Finally, if you are not cleansing your face properly, or if you are using products that are too harsh for your skin, this can also lead to an oily complexion. To help reduce oiliness, you can try using a gentle cleanser and using oil-free products on your face. You can also try using a toner or astringent to help remove excess oil.
