Celebrity cosmetologist Dr Monica Kapoor says, “Oily Skin or a combination type, ages slowly as compared to skin that’s dry. That’s because the oil (sebum) produced by the oil (sebaceous) glands serve to keep the skin lubricated, nourished, and moisturised, preventing fine lines and wrinkles.” Sebaceous glands produce sebum to keep your skin soft and moisturised. When too much sebum is produced, skin appears oily and this oily skin can also lead to acne and other skin problems. Hormones and genetics are the main factors for oily skin.
