Skin Health: Sesame oil is rich in zinc, which is one of the most important minerals in the body for your skin. It can increase skin elasticity and smoothness, helping to reduce the appearance of age spots and eliminate skin conditions, including premature aging. Sesame oil can also be used as a sunscreen because it creates a protective layer on the skin, which is another way of protecting the body from foreign substances or toxins that get in through the skin. In some cultures, sesame oil has even been used to treat fungal diseases on the skin.
