Squalene, an unsaturated oil found in foods like wheat germ, tuna, rice bran, and olive oil is proven to be beneficial to the skin and overall health. Squalene is similar to vitamin A, and research has found the oil works to naturally soften dry skin, treat dermatitis, smooth out wrinkles, and fight against cancer.

Squalene is available in food sources and is also produced naturally in the liver. Studies have found that squalene deficiency is associated to dry, scaly skin and premature aging. Adding squalene to your diet will slow down signs of aging and give your skin a healthy glow.

Squalene was discovered in the early 1900s, but extensive research of the oil didn't begin until 1930 after researchers found that sharks—who produce high quantities of squalene in their livers—do not develop cancer or tumors.

Further studies have revealed that squalene controls cholesterol and triglyceride levels, restores oxygen in cells increasing metabolism at a cellular level, works as an antioxidant, detoxifies the body, and guards against substances that threaten the immune system.

In addition, preliminary research has shown squalene helps prevent against skin cancer, chemically induced cancers, and weakens existing tumors.
