Oily skin is a common skin type characterised by the production of excess oil on the skin’s surface. This can lead to clogged pores, acne, and a shiny or greasy appearance. Some common causes of oily skin include genetics, hormone imbalances, and certain medications. It is important to cleanse the skin regularly using sebum-controlling cleansers. Additionally, you can try using toners and astringents to help control oil production, and consider using a clay mask or other products designed to absorb excess oil. Finally, use sunscreen to protect your skin from the sun’s harmful rays.
