Olive oil is a natural oil extracted from olives, which is the fruit of the olive tree. It is considered a major part of the Mediterranean diet since it contains monounsaturated fatty acids, which are known to be healthy. Apart from reducing your risk of chronic diseases, olive oil is also great for the skin. Research suggests that the oil is naturally high in squalene, an oil that mimics your skin’s natural sebum, which leaves your skin feeling smooth and soft. Olive oil is full of antioxidants that prevent cellular damage and help fight environmental skin damage. Apart from being great for the skin, olive oil can also do wonders for your hair.
